=== Bahrain ===
In [[Bahrain]] every citizen and resident must hold an [[National ID card|Identification Card]] ({{langx|ar|بطاقة الهوية}}) and thus has a Personal Number ({{langx|ar|الرقم الشخصي}}) which consists of 8 digits followed by a [[check digit]] (Total: 9 digits). In general, it has the following format: YYMMNNNNC, where YYMM is the year and month of birth, NNNN is a random number, C is the [[check digit]]. However, a minority of citizens and residents have Personal Numbers that do not follow that format.

It is possible to obtain a Distinctive Personal Number ({{langx|ar|الرقم الشخصي المميز}}), only for newborn infants and it is optional and not compulsory, for a fee (US$130, 200, or 260 depending on the category).

Another local name for the Personal number is Central Population Registration (CPR) Number ({{langx|ar|الرقم السكاني}}) which was used before the inception of the Central Informatics Organization (CIO) ({{langx|ar|الجهاز المركزي للمعلومات}}).

=== Bangladesh ===
{{main|Bangladeshi national identity card}}
In [[Bangladesh]] the National Identity card is issued by National Identity Registration Wing of the Election Commission. The National Identity card or NID card is a compulsory identity document issued to every Bangladeshi citizen upon turning 16 years of age. The NID is a government issued photo ID just like the Bangladeshi Driver's licence, which is also a biometric, microchip embedded, smart identity card. The NID is required by Bangladeshi citizens for multiple essential public services, such as obtaining utility connections, as well as private services, such as opening bank accounts, in Bangladesh. Initially paper based laminated NID cards were issued since 2006. Then the paper based laminated NID cards were replaced by biometric and microchip embedded Smart NID cards for all adult citizens in Bangladesh from 2016 onwards. The Smart NID card contains the card holder's ID number. The government provides the Smart NID card free of charge to all adult citizens of Bangladesh.<ref>{{Cite news|url=http://www.dhakatribune.com/bangladesh/2016/10/02/19424/|title=PM launches smart ID cards distribution {{!}} Dhaka Tribune|date=2016-10-02|newspaper=Dhaka Tribune|language=en-US|access-date=2017-02-04|archive-date=2017-05-04|archive-url=https://web.archive.org/web/20170504132308/http://www.dhakatribune.com/bangladesh/2016/10/02/19424/|url-status=live}}</ref><ref>{{Cite news|url=http://bdnews24.com/bangladesh/2016/10/02/distribution-of-machine-readable-nid-cards-for-bangladeshi-citizens-inaugurated|title=Distribution of 'smart' NID cards for Bangladesh citizens inaugurated|newspaper=bdnews24.com|access-date=2017-02-04|archive-date=2016-11-21|archive-url=https://web.archive.org/web/20161121074058/http://bdnews24.com/bangladesh/2016/10/02/distribution-of-machine-readable-nid-cards-for-bangladeshi-citizens-inaugurated|url-status=live}}</ref>

=== China ===
{{Main|Resident Identity Card#Identity card number}}
In [[China]], an ID card is mandatory for all citizens who are over 16&nbsp;years old (Except for overseas citizens without registered residence in the country). The ID number has 18 digits and is in the format RRRRRRYYYYMMDDSSSC, which is the sole and exclusive identification code for the holder (an old ID card only has 15 digits in the format RRRRRRYYMMDDIII). RRRRRR is a standard code for the [[Administrative divisions of the People's Republic of China|administrative division]] where the holder is born (county or a district of a city), YYYYMMDD is the birth date of the holder, and SSS is a sequential code for distinguishing people with identical birthdates and birthplaces. The sequential code is odd for males and even for females. The final character, C, is a checksum value over the first 17 digits. To calculate the checksum, each digit in order is multiplied by a weight in the ordered set [7 9 10 5 8 4 2 1 6 3 7 9 10 5 8 4 2] and summed together. The sum modulus 11 is used as an index into the ordered set [1 0 X 9 8 7 6 5 4 3 2], with the first index being zero. The indexed value is the checksum digit. In 15 digit IDs, III is an identification number created through certain mathematical methods (the last digit might be an English letter, such as X). The ID card is used for residential registration, army enrollment registration, registration of marriage/divorce, going abroad, taking part in national exams, and other social or civil matters.

=== Hong Kong ===
In [[Hong Kong]], a [[Hong Kong Identity Card]] (HKID) is mandatory for all residents aged over 11, subject to limited exceptions. HKID cards contain the bearer's HKID number, of which the standard format is X123456(A). X represents one or two letters of the alphabet. The numerals may represent any Arabic number. A is the [[check digit]], which has 11 possible values from 0 to 9 and A. The letters and numbers are not assigned arbitrarily. Additionally, one can view the international securities identification numbers organization that helps assign ISIN codes to securities.

=== India ===

On 28 January 2009, the Indian Government established an Authority called the [[Unique Identification Authority of India]] (UIDAI) to issue a ''Unique Identification Number'' to all residents of India. It is the biggest biometric ID programme in the world due to the large population of India.<ref name="Shankar 2015">{{cite web | last=Shankar | first=Besta | title=Aadhaar Becomes World's Biggest Biometric ID Programme | website=International Business Times, India Edition | date=27 April 2015 | url=http://www.ibtimes.co.in/aadhaar-becomes-worlds-biggest-biometric-id-programme-630499 | access-date=24 April 2016 | archive-date=6 May 2016 | archive-url=https://web.archive.org/web/20160506015334/http://www.ibtimes.co.in/aadhaar-becomes-worlds-biggest-biometric-id-programme-630499 | url-status=live }}</ref> UIDAI's [[Aadhaar|Aadhaar card]] project gives each eligible Indian resident a unique 12 digit identification number, along with recording their biometrics such as iris scan and fingerprints on a UIDAI database and the card is being rolled out to all such residents.<ref name="Parameshwari Ramaswamy">{{cite web | last=Ramaswamy | first=Parameshwari | title=Understanding the UID Aadhaar project and IT's role in its success | website=ComputerWeekly | date=September 2011 | url=http://www.computerweekly.com/tutorial/Understanding-the-UID-Aadhaar-project-and-ITs-role-in-its-success | access-date=24 April 2016 | archive-date=14 January 2017 | archive-url=https://web.archive.org/web/20170114211955/http://www.computerweekly.com/tutorial/Understanding-the-UID-Aadhaar-project-and-ITs-role-in-its-success | url-status=live }}</ref> Though contrary to popular belief Aadhaar is not a proof for citizenship.

Before Aadhaar, the closest India has come to this is the [[Permanent account number]] (PAN), issued by the Income Tax Office, for purposes of tracking income and income taxes. It has gained use as a means of identification for activities like getting a phone connection. A total of 24.37 crore (243.7 million) PANs have been allotted as of 24 February 2016.<ref name="Times of India 2016">{{cite web | last=PTI | first=From | title=Over 24.37 crore PAN cards {{sic|allo|ted|nolink=y}} in country, I-T department says | website=The Times of India | date=24 February 2016 | url=http://timesofindia.indiatimes.com/business/india-business/Over-24-37-crore-PAN-cards-alloted-in-country-I-T-department-says/articleshow/51124182.cms | access-date=24 April 2016 | archive-date=27 April 2016 | archive-url=https://web.archive.org/web/20160427231541/http://timesofindia.indiatimes.com/business/india-business/Over-24-37-crore-PAN-cards-alloted-in-country-I-T-department-says/articleshow/51124182.cms | url-status=live }}</ref>

=== Indonesia ===
In [[Indonesia]], each citizen is issued a unique 16 digit number known as a ''Nomor Induk Kependudukan''. The number is given to all Indonesian citizens. The format is PPRRSSDDMMYYXXXX where PP is a two digit [[Administrative divisions of Indonesia|province]] code, RR is a two digit regency or city code, SS is a two digit district code, DDMMYY is the date of birth (DD is added by 40 for females), and XXXX is a four digit randomized number. The number is stated on the [[Indonesian identity card]].

Since 2012, the [[Government of Indonesia|government]] rolled out the e-KTP (''Elektronik Kartu Tanda Penduduk'', "Electronic Citizen ID Card") which is an RFID card containing encrypted information of a citizen's electronic signature, scans of a citizen's [[Iris (anatomy)|irises]] and ten fingerprints, and a high-resolution photograph.

=== Iran ===

All Iranian citizens aged 15 or older are required to apply for an [[Iranian national identity card]] (کارت ملی/kart-e-meli). The card includes the holder's 10-digit National Identification Number, formatted as follows: XXX-XXXXXX-X.

=== Iraq, Republic of ===
{{Main|Iraq National Card}}

Every [[Iraqi people|Iraqi]] citizen must have a Nationality Certificate (شهادة الجنسية) and a civil Identification Document (هوية الأحوال المدنية). In 2016, both documents were replaced with [[Iraq National Card|National Card]] (البطاقة الوطنية), a [[Biometrics|biometric]] ID card.

=== Israel ===
An ''Identity Number'' ({{langx|he|מספר זהות|Mispar Zehut}}) is issued to all Israeli citizens at birth by the [[Ministry of Interior (Israel)|
Ministry of the Interior]]. It is composed of nine digits: a one-digit prefix, seven digits, and a final [[check digit]]. Blocks of numbers are distributed to hospitals, and individual numbers are issued to babies upon discharge from hospital. Temporary residents (category A-5) are assigned a number when they receive temporary resident status.

An Identity Card, (Hebrew: ''[[Teudat Zehut]]''), bearing an Identity Number, is issued to all residents over 16&nbsp;years old who have legal temporary or permanent residence status, including non-citizens.

=== Japan ===
[[Individual Number|Japan's national identification number system]], known within the country as "My Number" ({{langx|ja|マイナンバー}}), went into effect from 2016. The number consists of 12 digits, and one is assigned to each resident of Japan, including non-Japanese long-term residents with valid residency permits.

=== Kazakhstan ===
In [[Kazakhstan]] there is a 12-digit Individual Identification Number for natural persons (abbreviated in {{langx|kk|ЖСН}}, ''ZhSN''; in {{langx|ru|ИИН}}, ''IIN'', with first six digits representing person's date of birth in the YYMMDD format) and a 12-digit Business Identification Number for legal entities (companies).

Until its abolishment on 1 January 2013, the 12-digit Taxpayer's Registration Number ({{langx|kk|Салық төлеушінің тіркеу нөмірі}}; {{langx|ru|Регистрационный номер налогоплательщика}}, usually abbreviated as РНН, ''RNN'') was more popular in dealings with authorities as well as with businesses.

=== Kuwait ===
In Kuwait, the 12-digit national identification number is the Civil Number ({{langx|ar|الرقم المدني}}). It follows the format NYYMMDDNNNNN and is issued and put on the Civil ID and managed by the Public Agency for Civil Information (PACI) {{langx|ar|الهيئة العامة للمعلومات المدنية}}.

The Civil ID contains the holder's name in Arabic and English, a photo, gender, date of birth, current address, and a digital memory.

The Civil Number is issued for citizens and residents, and it is used for tasks such as opening a bank account, getting free medical care, or even taking some tests like the [[IELTS]] exam. Passports can be used instead for those who don't have Civil IDs, such as tourists.

=== Macau ===
In Macau, there are two types of ID cards: Permanent Resident Identity Card (BIRP) and Non-Permanent Resident Identity Card (BIRNP). The identification number has 8-digit standard format: NNNNNNN(N), where N is a numeric digit 0–9. The first numeric digit N has special meaning, and it can be one of the following digits: '1', '5' or '7'.

* '1': The first-time date of issuance of ID card to the bearer was 1992 or later.
* '5': The predecessor of the ID card was the Portuguese National Identity Card (BI), issued by Macau Civil Authority.
* '7': The predecessor of the ID card is Macau Identity Card, issued by Macau Public Security Police.

During Portuguese rule, Macau had no unified identification system, and several departments had the authority to issue identity cards to Macau citizens and residents. Since 1992, the Identification Department (once known as SIM, now called DSI) has become the unitary authority to issue identity cards. It has adopted the above-mentioned numbering policy.

Macau's Finance Department has also adopted identification number as a tax reporting number, for tax filing purposes.

=== Malaysia ===
{{Main|National Registration Identity Card Number (Malaysia)}}

In [[Malaysia]], a 12-digit number (format: YYMMDD-SS-###G, since 1991) known as the National Registration Identification Card Number (NRIC No.) is issued to citizens and permanent residents on a MyKad. Prior to 1 January 2004, a separate social security (''[[SOCSO]]'') number (also the old IC number in format 'S#########', S denotes state of birth or country of origin (alphabet or number), # is a 9-digit serial number) was used for social security-related affairs.

The first group of numbers (YYMMDD) are the date of birth. The second group of numbers (SS) represents the place of birth of the holder - the states (01–13), the federal territories (14–16) or the country of origin (60–85). The last group of numbers (###G) is a serial number in an unidentified pattern which is randomly generated. The last digit (G) is an odd number for a male, while an even number is given for a female.

=== Nepal===
Nepal is soon introducing National Identification Card. It is a Bio-metric smart card which will hold all the important details of an individual. A department level central body under the Ministry of Home Affairs named National ID Management Center has been established on 2011-07-17 AD, pursuant to the decision of 2010-06-30 AD of Nepal Government.

=== Pakistan ===
{{Main|National Database and Registration Authority}}
After the [[Partition of India|independence]] of [[Pakistan]], [[Prime Minister of Pakistan|Prime Minister]] [[Liaquat Ali Khan]] launched the [[Personal Identity System]] (PIS) program to issue national identification cards to the citizens of Pakistan and Muslim refugees settling in Pakistan. Since the 1960s, [[Pakistan]] has been issuing National Identity Card (commonly known by the acronym, NIC) numbers to its citizens. These numbers are assigned at birth when the parents complete the child's birth registration form (B-Form), and then a National Identity Card (NIC) with the same number is issued at the age of 18. Until, 2001 NIC numbers were 11 digits long. In 2001–2002, the [[National Database and Registration Authority]] (NADRA), started issuing 13-digit NIC numbers along with their new biometric ID cards. The first 5 digits are based on the applicant's locality, the next 7 are serial numbers, and the last digit is a check digit. The last digit also indicates the gender of the applicant; an even number indicates a female and an odd number indicates a male. The old numbers are invalid as of 2004.

As of 2012, NADRA has started to issue SMART ID cards which include an encrypted chip. The SMART card plan is to be extended to disburse social benefits as well as to allow the heirs of the card to get life insurance at the death of the card holder. This also allow citizens verify their card status through Citizen Verification Service offered by NADRA which enable citizens to verify their own status in NADRA database.

Every citizen has an NIC number for activities such as registering as a voter, voting in the general elections, paying taxes, opening a bank account, getting a utility connection (phone, cell phone, gas, electricity) purchasing or renting property, completing secondary education, acquiring higher education or applying for a job in most cases. However, since a majority of births in the country are not registered, and a large number of Pakistanis do not conduct any of the activities described above, most do not have ID cards. Obtaining an NIC card costs 100 rupees (US$1.66 - almost the average daily income), and this reduces the number of people who can afford it. In 2006, NADRA announced that it had issued 50&nbsp;million CNIC (the C standing for Computerized) numbers, which is approximately one-third of the population. In June 2008, the federal government announced it would start issuing CNIC cards for free.

In addition to NIC/CNIC companies and individuals in business and employment with taxable income are required to register with [[Federal Board of Revenue]] (FBR) and have their National Tax Number (commonly known as NTN). The tax number is mainly used only for taxation purposes and is rarely used otherwise as compared to other countries. New NTN certificates are being issued with computerized NIC numbers and old NTN certificates bearing old NIC numbers will become invalid.<ref>{{cite web |url=http://www.fbr.gov.pk/newntn/ |title= Federal Board of Revenue!

=== Singapore ===
In [[Singapore]] the [[National Registration Identity Card]] (NRIC) is issued to Singapore citizens and permanent residents. Permanent residents (PR) are issued with NRIC number similar to citizens.

The NRIC contains a unique number that identifies the person holding it, and is used for almost all identification purposes in Singapore, including authentication when accessing the Singapore government's web portal. Citizens and permanent residents are issued with identity number starts with prefix S (born before 2000) and T (born in or after year 2000), followed with a 7-digit number and a checksum alphabet. For citizens and permanent residents born after 1968, the first two digits of the 7-digit number indicate their birth year.

Long-term pass holders (e.g. people holding work permits, employment passes or student passes) are issued a similarly formatted Foreign Identification Number (FIN) on their long-term passes, with prefix F (registered before year 2000) and G (registered in or after year 2000).

=== South Korea ===
{{Main|Resident registration number}}
In South Korea, every Korean resident is assigned a Resident's Registration Number (주민등록번호), which has the form 000000–0000000. The first six digits is their birthday in the format YYMMDD. The first digit of the last seven digits is determined by the century of birth and the gender as follows:

* 1: males, holding Korean nationality, born 1900–1999
* 2: females, holding Korean nationality, born 1900–1999
* 3: males, holding Korean nationality, born 2000–2099
* 4: females, holding Korean nationality, born 2000–2099
* 5: male foreigners sojourn in Korea, born 1900–1999
* 6: female foreigners sojourn in Korea, born 1900–1999
* 7: male foreigners sojourn in Korea, born 2000–2099
* 8: female foreigners sojourn in Korea, born 2000–2099
* 9: males, holding Korean nationality, born before 1900
* 0: females, holding Korean nationality, born before 1900

(For example, a male citizen who was born on 27 May 2001 is assigned the number 010527‒3******, and a female citizen which was born on 24 March 1975 is assigned the number 750324‒2******.)

The next four digits mean the region of his/her birth registration, and the next 1 digit is a serial number of registration within the date and the region. The last digit is a [[check digit]].

=== Sri Lanka ===
In [[Sri Lanka]], all citizens over the age of 15 need to apply for a [[National identity card (Sri Lanka)|National Identity Card]] (NIC).

NICs issued before 1 January 2016, each NIC has a unique 9 digit number and one letter, in the format 000000000A (where 0 is a digit and A is a letter). The first two digits of the number are the holder's year of birth (e.g.: 91xxxxxxxx for someone born in 1991). The next three digits contain the number of days in the year of the person's birth. For females, 500 is added to the number of days. The next three digits are serial number of the issued day. The next digit is the check digit. The final letter is generally a 'V' which indicates that the holder is eligible to vote in the area. In some cases the final letter can be 'X' which usually indicates the holder is not eligible to vote; possibly because they were not permanent residents of Sri Lanka when applying for an NIC.

From 1 January 2016, each new NIC has a unique 12 digit number. The first four digits of the number are the holder's year of birth (e.g.: 197419202757 for someone born in 1974). The next three digits contain the number of days in the year of the person's birth. For females, 500 is added to the number of days. The next four digits are the serial number. The last digit is the check digit.

=== Republic of China (Taiwan) ===
In Taiwan, an [[Republic of China National Identification Card|ID card]] is mandatory for all citizens who are over 14&nbsp;years old. Every citizen has a unique ID number. The ID card has been uniformly numbered since 1965. A valid National Identification number consists of one letter and nine-digits, in the format A########C. The letter ("A") records the card holder's first [[Administrative divisions of the Republic of China|location]] of household registration, which is usually where they were born. The first digit depends on [[gender]]; 1 for male, 2 for female. The last digit ("C") is a [[checksum]]. Thus the total number of IDs is 208,000,000.<ref name="jidanni">{{cite web |url=http://jidanni.org/comp/checksums/taiwanidchecksum |title=Compute Taiwan citizen and resident identification number checksums |publisher=Jidanni.org |access-date=2014-03-09 |archive-date=2013-10-29 |archive-url=https://web.archive.org/web/20131029202938/http://jidanni.org/comp/checksums/taiwanidchecksum |url-status=live }}</ref>

It consists of a 13-digit string in the format N-NNNN-NNNNN-NN-N, which is assigned at birth or upon receiving citizenship. The first digit signifies type of citizenship, the second to fifth the office where the number was issued, the sixth to twelfth are group and sequence numbers, and the last digit acts as a check digit.
