This is the structure of the data file to provide to the FDIC information related to each customer who has an account or sub-account reported in the deposit data or sweep/automated credit account file. If data or information are not maintained or do not apply, a null value in the appropriate field should be indicated. The file will be in a tab-or pipe-delimited ASCII format. Each file name will contain the institution's FDIC Certificate Number, an indication that it is a customer file type and the date of the extract. The files will be encrypted using an FDIC-supplied algorithm. The FDIC will transmit the encryption algorithm over FDICconnect.

Note: Each record must contain the customer's name and permanent legal address. Fields 4-12 relate to the customer name for individuals only. Fields 13-14 relate to the customer name for entities other than individuals. Some systems provide for separate fields for name, street address, city, state, ZIP, and country, all of which are parsed out. Others systems may simply provide multiple lines for name, street address, city, state, ZIP, with no distinction. In this case, certain name and address data elements must be parsed and provided in the appropriate fields.
