Editing National identification number (section)

=== Chile ===
In [[Chile]] the National Identification Number is called RUN ''(Rol Único Nacional)'' but is usually called RUT ''(Rol Único Tributario)'' since the number is the same as the one used for tax purposes. The main difference between them is that a RUN is only assigned to natural persons, while [[juristic person]]s can only get a RUT number.

In the case of natural persons, the RUN/RUT number is used as a national identification number, as a taxpayer number, as a social insurance number, as a driver's license number, for employment, etc. It is also commonly used as a customer number in banks, retailers, insurance companies, airlines, etc. Until the end of August 2013, the RUN was also used as the passport number. After this date, Chilean passports have had unique numbers.

Since well before 1990, every baby born is given a RUN number; it was previously assigned when applying to get an ID card. Non-Chilean residents also get a RUN and an identification card. Every company or organization also must have a RUT for taxation purposes.

The RUN or RUT has 7 or 8 digits (for people alive today; in the past, there were persons with a 5- or 6-digit one) plus a [[check digit]] or letter (xx.xxx.xxx-z, z is {0-9, K}).
