I lost my EIN letter – how can I get a new one?
It’s important to note that the CP-575 cannot be reissued if lost. If you need official proof of your EIN after the letter has been lost, you must request a 147C letter. This letter is only issued after the original EIN letter has been lost or never received. Similar to the CP-575, the 147C states your business name, your official EIN, your business address, and a statement confirming your EIN is active.
You can request the 147C letter by calling the IRS Business & Specialty Tax Line toll-free at 1-800-829-4933. If you are calling from outside the United States, instead, you can dial 267-941-1099. These lines are usually available between 7:00 AM and 7:00 PM EST. Be prepared to verify your identity and confirm you’re authorized to receive the document. Once verified, the IRS agent will ask you if you’d like to receive your 147C letter via physical mail or fax. Fax is immediate, while mail will take 4-6 weeks.
