The SS-4 Letter, or the IRS confirmation associated with an Employer Identification Number (EIN) application, serves as official proof of a business’s tax identification. If the original letter is lost or needs to be reissued, knowing the right process helps owners and administrators verify their EIN quickly and accurately. This guide explains how to obtain a copy, what information you’ll need, and what to expect during the request.
What Is The SS-4 Letter
The SS-4 Letter is the formal document you receive from the Internal Revenue Service after submitting Form SS-4 to obtain an Employer Identification Number. This letter confirms your business’s EIN and provides essential details tied to the account, such as the legal name, tax classification, and filing requirements. For many U.S. businesses, the SS-4 Letter or its corresponding EIN verification letter (often labeled as CP 575 or CP 575A) is the primary proof of identity for banking, vendor contracts, payroll, and tax filings. As a durable source of identification, it’s common to need a copy if the original is misplaced or if a lender or partner requires updated documentation.
Reasons To Get A Copy Of The SS-4 Letter
- Opening a business bank account that requires EIN verification
- Completing vendor or contractor onboarding and tax forms
- Filing tax returns or payroll reports with accurate EIN information
- Replacing a lost or damaged confirmation letter for records
- Resolving discrepancies in business records or with the IRS
How To Request A Copy Of The SS-4 Letter
There are several ways to obtain a copy of the SS-4 Letter or the EIN verification letter, depending on your circumstances and the information you have available. The IRS provides options designed for quick access and security.
Call The IRS Business & Specialty Tax Line
For many taxpayers, calling the IRS is the fastest route. The Business & Specialty Tax Line can help verify your EIN and provide a copy of the confirmation letter or an updated verification letter. Have the following ready: legal business name, trade name (if applicable), complete address, the responsible party’s name, and the EIN you believe to be correct. Expect identity verification steps to protect sensitive data. The typical process involves confirming identifying details and requesting a replacement letter or a verified copy of the EIN confirmation.
Submit A Written Request By Mail
If phone access is not convenient, a written request sent to the IRS can also work. Include the business’s legal name, current and previous addresses, the EIN (if known), and a clear statement requesting a copy of the SS-4 Letter or EIN verification letter. Do not send highly sensitive information in unsecured methods; consider a secure mailing option if available and keep copies for your records. Processing times may be longer than a phone request.
Use The IRS Online Resources
Some EIN-related information can be accessed via online IRS portals for businesses. While not every account offers a direct download of the SS-4 Letter, certain online services provide verification letters or status updates for existing EINs. If you already maintain an IRS online account for your business, log in to verify what documents are available for download and print a copy as needed. This option is especially helpful for quick access from anywhere with internet connectivity.
What If You No Longer Have Access To The Email Or Account On File
In cases where account access is compromised, contact the IRS to verify identity through alternative methods. A phone call with the appropriate verification steps can reestablish access and allow you to request a replacement letter. Accurate corporate details and a consistent business address can streamline the process.
What To Prepare Before Requesting A Copy
- Legal business name and any DBA to ensure correct matching
- Physical address and mailing address on file with the IRS
- Employer Identification Number (EIN) if known
- Responsible party’s information such as owner or principal officer
- Proof of identity for authorized representatives, if required
Processing Times And Delivery
Processing times vary by method. Phone-based requests often yield faster results, sometimes the same day, while mail requests may take several weeks depending on IRS workload and security checks. Online access can provide near-immediate documentation if the portal supports a downloadable letter. For urgent needs, prioritize a phone request and confirm any anticipated delivery timeline with the representative. Always request an electronic copy when possible to minimize delays and ensure you have a durable digital record.
Tips For A Smooth Experience
- Ask for an EIN verification letter if the exact “SS-4 Letter” term isn’t used by the IRS in your communications.
- Double-check the business name, address, and EIN against internal records to prevent mismatches.
- Keep a secure digital copy and print a physical version for filing cabinets and lender requirements.
- Document the date of the request and the name of the IRS representative for future reference.
- If you still cannot obtain a copy, consider consulting a tax professional for guidance on alternative proof of EIN.
