A CP 575 Form is an Internal Revenue Service (IRS) notice confirming that the IRS has assigned an Employer Identification Number (EIN) to a business or other organization. The EIN is the organization’s nine-digit federal identification number, while the CP 575 is written evidence of the assignment. The notice identifies the entity associated with that number and can be requested when a bank or another institution needs to verify the EIN. It is commonly relevant to businesses that file federal tax returns or have employees. The original CP 575 notice is not the same as Form SS-4, which is the application used to request an EIN. Nor does having a CP 575 establish that an organization has completed every state or local registration it may need.

What Does a Cp 575 Confirm?
The CP 575 confirms that the IRS assigned the EIN shown on the notice to the entity identified there. The EIN is used to identify an organization for federal tax filing and reporting. It is not the notice itself. For a broader explanation of this identifying number, see a Tax Identification Number (TIN).
Check the legal name and EIN on the notice against the organization’s records before using it. A mismatch can create problems when information is supplied to a bank or entered on a federal tax document. Use the EIN exactly as displayed. If the entity’s legal name or responsible-party information has changed, check the applicable IRS process rather than assuming the notice has been updated automatically.
The notice confirms an EIN assignment. It is not a business license or tax return. It also does not, by itself, demonstrate that state or local tax accounts have been opened or that the organization has met every obligation connected with hiring workers.
How Is a Cp 575 Issued?
An organization applies for an EIN using IRS Form SS-4. Once the IRS assigns the number, it issues an EIN assignment notice. The application and the notice serve different purposes: Form SS-4 requests the EIN, while the CP 575 confirms the assignment. The IRS explains that an EIN is a nine-digit number assigned to entities for tax filing and reporting purposes.
Depending on how the EIN application is completed, the applicant may be able to save or print the assignment notice when the EIN is issued. Keep the notice with important business and tax records. The IRS recommends retaining the digital notice in permanent records and using the EIN on relevant submissions to the IRS and Social Security Administration.
For current guidance on the notice and access through an IRS Business Tax Account, consult the IRS page about understanding a CP 575 notice. Availability of online account features may depend on the entity and account access. Protect the notice because it contains information that can be used to identify the organization.
When Might an Organization Need It?
A bank or other institution may ask for the CP 575 when an organization opens an account or seeks a business service. An employer may also need to provide evidence of its EIN during payroll onboarding. The institution making the request determines which documents it accepts, so confirm whether it needs the CP 575 specifically or will accept another official EIN verification document.
In payroll, the EIN helps identify the employer on relevant federal tax records. It is distinct from payroll tax, which refers to the taxes associated with paying employees. The CP 575 can help a payroll administrator confirm that the employer’s name and EIN match the IRS assignment. It does not submit returns, make tax deposits, or replace other payroll activities.
For example, an employer setting up payroll may be asked to provide its EIN confirmation while completing provider records. That confirmation helps establish which entity’s EIN belongs on federal filings, such as a Quarterly Federal Tax Return. The employer may still need separate state tax or unemployment account information depending on where work is performed and which rules apply.
How Is It Different from Other Ein Documents?
The CP 575 is the IRS’s notice confirming the EIN assignment. Form SS-4 is the application submitted to obtain an EIN. An EIN is the nine-digit number itself. Keeping these distinctions clear helps prevent an application or a number recorded in internal files from being mistaken for an IRS-issued confirmation notice.
Letter 147C is another IRS document used to verify an EIN that was previously assigned. The IRS says its digital CP 575 can serve as a substitute for the original CP 575A-J notice series and Letter 147C. A bank or other institution may still specify which form of evidence it will accept, so check its requirements before sending documents.
Neither the CP 575 nor an EIN alone proves that an organization is registered for every tax or employment program that may apply. Federal employer obligations can include employer payroll taxes and FUTA. State requirements may involve separate registrations, including State Unemployment Insurance (SUI). Applicable duties depend on the organization and the work location.
What If the Cp 575 Is Missing?
First, check the organization’s permanent records and any files created when the EIN was obtained. If the notice is unavailable, do not apply for another EIN simply to replace the document. Contact the IRS to ask about EIN verification. The IRS states that the original CP 575A-J notice cannot be duplicated or recreated. Its guidance describes a digital CP 575 as a substitute that eligible users can access through Business Tax Account.
IRS verification is subject to its identity and authorization procedures. Only an authorized person should seek or share confidential business tax information. If the IRS verification document is not immediately available, ask the requesting bank or other institution what alternative evidence it accepts. Acceptance rules can differ by institution.
Store the CP 575 or other accepted confirmation securely and limit access to people who need it for legitimate business purposes. During contingent workforce program setup, having the correct employer identity and EIN available can help payroll administrators maintain consistent employer records. It is still important to confirm which organization is responsible for paying the workers and reporting the related taxes. The notice verifies an EIN; it does not decide the employment or payroll responsibilities of the parties involved.
