Note – First developed in 1970 by and for American local affiliate TV stations, the TV networks that serve the affiliates, and ad agencies, to distribute commercial television advertisements more efficiently. The ISCI coding system has been maintained and operated by the American Association of Advertising Agencies (AAAA) and the Association of National Advertisers (ANA) since 1992. Prior to then, ISCI was independently maintained by its users. An ISCI code is usually a set of 8 characters, the first four being alphabetic, and the remaining four being numeric, in the format ‘ABCD1234’ . The alphabetical characters usually represent the advertiser (some examples are QWAN for Wells Fargo Bank, KOCL (and more recently CL) for Coca-Cola, and PEMX for Pepsi), and the numeric characters usually represent the spot itself, with different numbers used for either different spots, or different versions of the same spot.
