The CP 575 Confirmation Letter

The CP 575 is the official IRS letter confirming your EIN assignment. It contains your EIN, entity legal name, and assignment date. This is your primary proof of EIN for banking and tax filing.

Important: The IRS Does Not Reissue CP 575s

If you lose your CP 575, the IRS will not send a replacement. Request a 147C verification letter instead by calling 1-800-829-4933 (domestic) or 267-941-1099 (international).
