9.0 SIN Usability File

As part of ongoing efforts to ensure program integrity, the beneficiary and holder SIN information will be verified monthly with the SIR. As a result of this monthly SIN validation, certain beneficiary and holder SINs will be identified (flagged) by SIR as "SIN is not useable". As well, a beneficiary or holder SIN may have a status of “SIN is useable’. This is a result of SIR re-activating (un-flagging) a beneficiary or holder SIN.

In order to help issuers identify the usability of beneficiary and holder SINs, the CDSP system will be sending out a new file to issuers called the SIN Usability File (SUR) each month. This file will contain a new record type called the RT 921 - SIN usability record consisting of:

  • A header record - type "001"
  • A series of SIN usability records - type "921"
  • A trailer record - type "999".

PURPOSE: The record type “921” reports SIN usability issues to the authorized agent.
