The CP 575 Form is a notice sent by the Internal Revenue Service (IRS) to confirm that an organization has been assigned an Employer Identification Number (EIN). Officially titled “Notice CP 575”, this document is typically mailed within 4–6 weeks after an EIN application is approved.
It is not a form you fill out, but rather a confirmation letter issued by the IRS. It contains vital information such as your EIN, legal business name, and filing requirements - making it an important document for banking, licensing, payroll, and tax purposes.

Key Facts
- Sent Automatically by the IRS: It’s mailed to the business address listed on the EIN application (Form SS-4) once the EIN is issued.
- Includes Your Official EIN: The CP 575 confirms the unique 9-digit Employer Identification Number used for tax filing and business identification.
- Needed for Key Business Activities: Many banks, vendors, and government agencies require a copy of CP 575 when opening business accounts, applying for licenses, or enrolling in payroll services.
- Not Reissued If Lost: The IRS does not send a second CP 575. If it’s lost, businesses must request an EIN Verification Letter (Form 147C) instead.
- Applies to All Types of Entities: Corporations, LLCs, nonprofits, and sole proprietors can all receive a CP 575 after applying for an EIN.
- Usually One Page Long: The letter contains the legal business name, EIN, responsible party, tax forms required, and filing deadlines.
1. What is the CP 575 form used for?
It confirms that the IRS has officially issued your EIN and includes your business's legal name and filing obligations. It's often required to open bank accounts or establish business credit.
2. How do I get a copy of the CP 575 form?
You don’t “get” it by request - it’s automatically sent by the IRS after you successfully apply for an EIN (via Form SS-4).
3. What if I lost my CP 575 letter?
The IRS won’t reissue it. Instead, you can call the IRS and request an EIN Verification Letter (Form 147C), which is accepted in place of the CP 575.
4. Is the CP 575 required to open a business bank account?
In many cases, yes. Banks often require the CP 575 or a 147C letter as proof of EIN assignment for regulatory compliance.
5. Can I receive the CP 575 electronically?
No. The IRS sends it by mail only to the physical address listed on your EIN application. If you applied online, you may get immediate EIN confirmation, but the CP 575 still arrives by post.
