On October 30, 2005, the Central Contractor Registration (CCR) began validating the Taxpayer Identification Number and Taxpayer Name of each new and updating CCR registrant with the Internal Revenue Service (IRS) records.

A Taxpayer Identification Number (TIN) is a nine-digit number, which is either an Employer Identification Number (EIN) assigned by the Internal Revenue Service (IRS) or a Social Security Number (SSN) assigned by the Social Security Administration (SSA).

The TIN matching process is a joint effort between the General Services Administration (GSA), Department of Defense (DoD), and the IRS to improve the quality of data in government acquisition systems. A notice has gone out to CCR registrants informing them of the IRS validation in CCR registration. In order to complete your CCR registration and qualify as a vendor eligible to bid for federal government contracts or apply for federal grants, the TIN and Taxpayer Name combination you provide in the IRS Consent Form must match exactly to the TIN and Taxpayer Name used in federal tax matters. It will take one to two business days to validate new and updated records prior to becoming active in CCR.

For a view of the new IRS Consent form from CCR Update, please see IRS Consent Form.
