Can two airlines have the same IATA code?
Unfortunately it is true that two airlines can have the same IATA code. The airlines are generally in different regions. Controlled duplicates are issued to regional airlines whose destinations are not likely to overlap, so that the same code is shared by two airlines.
Does IATA and ICAO have the same standards?
In short: ICAO codes are four-letter codes used by a appendant body of the United Nations to designate international flights and govern the standards of air travel. IATA codes are three-letter codes used by a non-governmental trade organization to efficiently identify airports, airlines, and flight paths for consumers.

How are IATA codes assigned?
IATA code assigned to the airport by IATA consists of 3 letters and created through the airport and city names. Codes are mostly generated with the letters chosen from a city’s name. 2-character codes of airports are given in 1930 for the first time. Then three-character codes started to be used.
How are airport codes decided?
The three-letter code is determined by first ensuring that it’s unique and not in use by any other entity. The code might be assigned based on the name of the airport, the name of the city, or some other meaningful and relevant identifier if those letters are already taken.

Why do two airlines have the same IATA code?
Controlled duplicates are issued to regional airlines whose destinations are not likely to overlap, so that the same code is shared by two airlines. This happens because IATA uses a 2-letter code for for airlines which has a limited range of available codes.
Are there airports that do not have an ICAO code?
In some cases, smaller general aviation airports or private airfields do not have an ICAO code, nor an IATA code. Illinois, for example, has a great number of “general aviation” and public-use airports that do not have EITHER code assigned — or, they have an ICAO code but not an IATA code. Or vice versa.
What does a controlled duplicate IATA code mean?
Controlled duplicates are issued to regional airlines whose destinations are not likely to overlap, so that the same code is shared by two airlines. The controlled duplicate is denoted here, and in IATA literature, with an asterisk (*). My working theory is that possibly Heli France has shutdown?
How many letters are in an IATA code?
IATA codes consist of a three-letter code that is usually related to the city or region served by the airport or the name of the aerodrome that existed before the creation of the airport.
