An '''N11 code''' (pronounced ''Enn-one-one'') is a three-digit dialing code used in [[abbreviated dialing]] in the [[North American Numbering Plan]] (NANP). The mnemonic ''N'' stands for the digits ''2'' through ''9'' and thus the syntax stands for the codes ''211'', ''311'', ''411'', ''511'', ''611'', ''711'', ''811'', and ''911''. These dialing codes provide access to special local services, such as ''911'' for emergency services, which is a facility mandated by law in the United States. The (FCC) in CC Docket 92-105, specified how the N11 codes of 211, 311, 511, 711 and 811 codes would be used for various types of public information under NANP.<ref>{{cite web |url=https://www.fcc.gov/document/use-n11-codes-and-other-abbreviated-dialing-arrangementsclas-no |url-access= |title=The Use of N11 Codes and Other Abbreviated Dialing Arrangements(Clas No. 920485) |author=Staff writer |date=May 6, 1992 |department= |website=www.fcc.gov |agency=FCC |location= |arxiv= |asin= |bibcode= |doi= |doi-broken-date= |isbn= |issn= |jfm= |jstor= |lccn= |mr= |oclc= |ol= |osti= |pmc= |pmid= |rfc= |ssrn= |zbl= |id= |access-date=May 16, 2024 |url-status= |archive-url= |archive-date= |quote= }}</ref><ref>{{cite web |url=https://www.federalregister.gov/documents/2004/06/08/04-12830/the-use-of-n11-codes-and-other-abbreviated-dialing-arrangements |url-access= |title=Proposed RuleThe Use of N11 Codes and Other Abbreviated Dialing Arrangements |author=Staff writer |date=June 8, 2004 |department= |website=www.federalregister.gov |agency=Office of the Federal Register |arxiv= |asin= |bibcode= |doi= |doi-broken-date= |isbn= |issn= |jfm= |jstor= |lccn= |mr= |oclc= |ol= |osti= |pmc= |pmid= |rfc= |ssrn= |zbl= |id= |access-date=May 16, 2024 |url-status= |archive-url= |archive-date= |quote= }}</ref>

==Services==
N11-numbers provide access to special services. For example,
[[File:MUTCD D12-5.svg|thumb|upright|This US road sign reminds drivers and passengers about [[5-1-1]] service.]]
*[[2-1-1|211]]: [[Community]] services and information
*[[3-1-1|311]]: [[Municipality|Municipal government]] services, non-emergency number
*[[4-1-1|411]]: [[Directory assistance]]
*[[5-1-1|511]]: [[Traffic reporting|Traffic information]] or police non-emergency services
*[[6-1-1|611]]: [[Telephone company|Telephone company (telco)]] [[customer service]] and repair
*[[7-1-1|711]]: [[Telecommunications device for the deaf|TDD]] and [[Telecommunications relay service|Relay]] Services for the [[Hearing loss|deaf and hard of hearing]]
*[[8-1-1|811]]: Underground public [[utility location]] (United States);<ref>See Federal Communications Commission [http://fjallfoss.fcc.gov/edocs_public/attachmatch/DOC-257293A1.doc Document No. 92-105]</ref> non-emergency health information and services (Canada)
*[[911 (emergency telephone number)|911]]: [[Emergency service]]s ([[police]], [[fire department|fire]], [[Emergency medical services|ambulance]] and [[rescue]] services)

411 and 611 are commonly used in the United States, but not officially assigned by the [[Federal Communications Commission]].

The designation for special use in the NANP prevents their use as [[area code]]s and [[central office code|central office prefix]]es, eliminating about 8 million telephone numbers from assignment.

The assigned use of each N11 code may vary for the various countries, US states, and Canadian provinces of the NANP, but 911 is mandated in the [[United States]] and [[Canada]], 711 and 911 access is mandated by [[law]] in the United States, even within private networks (PBX, enterprise and cellular systems).

411 and 611 are supported by the service provider for the calling phone, but not all carriers provide these services. 411 and 611 (formerly 811) are typically blocked within enterprise or [[Business telephone system#Private branch exchange|private branch exchange]] (PBX) systems, including cellular telephone service purchased for an enterprise system, since 411 calls generally incur a fee and the service is now readily accessible by other means, and 611 services are managed by the enterprise in which the phone resides.

Other community services are provided through 211, but only if a [[nonprofit organization]], such as [[United Way of America]], or the local government operates it locally. Likewise, local, state or provincial government may, but do not uniformly, operate traffic information using 511. 811 was made mandatory in the United States in 2007; however, it has not been universally implemented. 711 is funded through the [[Telecommunications relay service|TRS Fund]], which telephone companies are mandated to maintain to provide Relay Services for the Deaf and Hearing Impaired.

==011==
Within the NANP, a leading digit of 0 or 1 indicates special dialing arrangements. ''1'' is the toll-dialing prefix, or ''trunk prefix''. [[List of international call prefixes|011]] is the international calling prefix, dialed before a [[country code]] to call internationally.
