Each registering FI will be given a FATCA ID that will be used for purposes of establishing and accessing the FI’s online FATCA account. For all FIs other than Member FIs, the FATCA ID is a randomly generated six character alphanumeric string. These 6 characters are upper case letters excluding the letter O, or numbers, or a combination of both. For Member FIs, the FATCA ID will be comprised of 12 characters: the first 6 characters will be the Lead FI’s FATCA ID, followed by a period, and the last 5 characters will be alphanumeric and assigned sequentially to each Member FI. The FATCA ID is not the same as the GIIN.
