# Comparison of alphabetic country codes

This is a comparison of the IOC, FIFA, and ISO 3166-1 three-letter codes, combined into one table for easy reference. Highlighted rows indicate those entries in which the three-letter codes differ from column to column. The last column indicates the number of codes present followed by letters to indicate which codes are present (O for Olympic, F for FIFA, and I for ISO) and dashes when a code is absent; capital letters indicate codes which match; lower case letters indicate codes which differ.

## Ambiguities

Currently, the only ambiguous trigraph between IOC, FIFA and ISO codes is:
* BRN - IOC code for Bahrain and ISO code for Brunei
Historically, ambiguous trigraphs include:
* ANT - IOC code for Antigua and Barbuda, and historical ISO and FIFA code for the Netherlands Antilles (until 2010)
* BUR - IOC code for Burkina Faso (since 1984), and historical ISO and FIFA code for Burma (until 1989)
In the following cases, a code for a historical country or territory matches a modern code of the country it merged into:
* VNM - historical IOC and ISO code for South Vietnam, became the ISO code for unified Vietnam
* YEM - historical ISO code for the North Yemen, became the generally accepted code for unified Yemen
Including other lists of country three-letter-codes increases the number of ambiguities. For example:
* AUS - IOC, FIFA and ISO code for Australia, but UNDP code for Austria (Australia is AUL there)

## List

This list only includes nations or territories that have been assigned at least one of these three types of country codes. For a more complete list of countries, see list of countries.
