# How can I obtain a copy of the IRS EIN Verification Letter (147C)?

If you lost your IRS EIN confirmation letter (CP 575), you can request an EIN verification letter called a **147C Letter** from the IRS. This letter is commonly accepted by banks, payment processors, and vendors as proof of your EIN.

## Information you should have ready
The IRS agent may ask for:

Only an authorized person (owner, officer, partner) can request it.

Fax is much faster.
