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’ .
