IATA codes are abbreviations that the International Air Transport Association (IATA) publishes to facilitate air travel. They are typically 1, 2, 3, or 4 character combinations (referred to as unigrams, digrams, trigrams, or tetragrams, respectively) that uniquely identify locations, equipment, companies, and times to standardize international flight operations. All codes within each group follow a pattern (same number of characters, and using either all letters or letter/digit combinations) to reduce the potential for error.
Aircraft type designators
- code XU is used to specify part of Russia east of (but not including) the Ural Mountains.

IATA timezone codes
- ISO 3166-1 alpha-2 country code is always used as first and second characters of time zone code.
- If country is not divided into separate time zones - no more characters added. Just 2 characters used.
- If country is divided into time zones - 3rd character of time zone code is a digit - number of time zone in country. Note: Russia is divided into 11 timezones, so number of time zone in country is specified by 2 digits - RU01, RU02, ... RU11.
- If some territories have the same local time, but different rules on Daylight saving time, - a letter can be added as 4th character to make unique codes for all such territories.
Example: Time zone code AU2 is used for Australian states New South Wales and Victoria (local time is UTC + 10 hours, DST begins at end of October). Time zone code AU2A is used for Tasmania (local time is UTC + 10 hours, DST begins at end of September). Time zone code AU2B is used for Queensland (local time is UTC + 10 hours, no DST).
