IRS Form Examples
BreezyBilling requires a copy of the CP 575 (also called SS-4) to authenticate a practice and confirm business details.
If the CP 575 is unavailable, the IRS 147C letter can serve as an alternative — a letter generated by the IRS to confirm your EIN.
If you lost or cannot find your CP 575, you can request a 147C by calling the IRS Business and Specialty Tax line at 1-800-829-4933.
