An inquiry of the Securities File should include type, serial number, and denomination. Issuer should be included for securities other than U.S. Treasury issues and currency. When all of this information is not available, an inquiry may be made by owner, by owner and type, by owner and originating agency case number, or by Social Security Number only. Inquiries may be made using the NIC Number only, if available. “BEARER,” “BLANK,” “UNKNOWN,” “UNK,” and “UNKN” are not to be used as names of owners for purposes of inquiry. Such inquiries will be rejected. An inquiry on a security gives access to single as well as group records in the Securities File.
