For DB28 Carrier’s World Area Code – OAI adds this to identify the carrier’s country - This three-digit code specifies the area of the world a CARRIER is headquartered. The first digit represents a major geographic area. “010” is the WAC for the United States – which is actually 010 but looks like 10 in the data. A Carrier WAC beginning with “4” is a carrier based out of Europe, etc.  The last two digits represent a subdivision of the area, such as a state or a country.  Contact the Office of Airline Information at the address listed on the cover for a complete list of these area codes.
