Can the IRS Send a Duplicate EIN Letter? What to Expect
When you apply for an Employer Identification Number (EIN) you normally receive an official confirmation from the IRS that documents the assignment. That confirmation — often called a CP 575 or, when reissued, a 147C — is commonly requested by banks, lenders, state agencies and payroll providers as proof of your business’s tax identity. Losing the original EIN letter raises practical hurdles: you may be unable to open or update bank accounts, enroll in certain payroll or benefits services, or show proof of registration to partners. Understanding whether the IRS can issue a duplicate EIN letter, what documents they will accept in its place, and the steps to request a replacement helps you resolve these operational issues quickly.
What exactly is an EIN confirmation and why does it matter?
The EIN confirmation is the IRS’s official record that an EIN was assigned to a business entity. Historically, the IRS mailed a CP 575 Notice when an EIN was issued; today you might also see Letter 147C, which serves as an official EIN verification or replacement. Institutions that require proof of EIN—banks opening business accounts, payroll companies setting up withholding, and state agencies or vendors confirming tax identity—typically accept one of these IRS letters because they display both the legal name and the nine-digit number. Retaining a copy of the original CP 575 or a 147C speeds routine transactions and reduces friction when third parties request tax identification documentation.
Can the IRS send a duplicate EIN letter or verification?
Yes. The IRS can provide an official verification of your EIN if you’ve lost the original CP 575. The most commonly used replacement is Letter 147C, which confirms the EIN and the entity name. The IRS does not normally reissue the exact original CP 575; instead it issues a current verification letter that serves the same purpose for banks and agencies. Keep in mind that the IRS will only release this information to an authorized person—typically the responsible party (owner, principal officer, or someone with Power of Attorney) who can verify identity. The replacement is an administrative confirmation and does not change your EIN or the underlying tax records.
How to request a replacement EIN letter from the IRS
To request a duplicate or verification letter, gather information that proves you are authorized to receive EIN details: the business name as it appears on IRS records, the EIN if you know it, the responsible party’s Social Security number or ITIN, and the responsible party’s date of birth. Call the IRS Business & Specialty Tax Line and ask for an EIN verification (many advisers request a Letter 147C). During the call agents will verify identity and may mail or fax the verification to the business address on file. If you are calling on behalf of the business, be prepared to present a signed Form 2848 (Power of Attorney) or Form 8821 (Tax Information Authorization) to prove authorization. Expect the IRS to mail official documentation; in many cases the mailed 147C arrives within about two weeks, though agents can sometimes confirm the number by phone at the time of the call.
Other documents that banks and agencies accept as proof of EIN
When you need to prove your EIN but prefer not to wait for an IRS letter, several alternative documents are commonly accepted. These alternatives come from the original application, prior filings, or transactions where the EIN was used.
- Copy of the original Form SS-4 you submitted when applying for the EIN (if you retained it).
- Previously filed tax returns or payroll tax filings that display the EIN.
- Bank account paperwork or loan documents that show the EIN and business name.
- State registration or licensing documents that include the federal EIN.
- IRS notices or transcripts that reference your EIN (Form 147C is preferred when available).
Practical tips, timelines and what to expect when you call
Before contacting the IRS, confirm the business address and responsible party information on your records so the phone call proceeds smoothly. If someone else will request the letter for you, submit Form 2848 or Form 8821 in advance and allow processing time. The IRS routinely mails replacement letters; typical turnaround can be a week or two, though timelines vary by workload and whether additional verification is needed. When you receive the replacement, retain both digital and physical copies in secure locations and notify banks or vendors that may require the document. If you applied for your EIN online and downloaded a confirmation file at the time, make a habit of saving and backing it up immediately to avoid future delays.
