Your employer’s EIN, when it appears on a pay stub, sits with the company’s identifying information — usually in the header near the business name and address, sometimes in a footer or tax-summary block. Look for a label such as FEIN, EIN, Federal Tax ID, Fed Tax ID, or Tax ID Number, followed by a nine-digit number in two-digit-hyphen-seven-digit format (for example, 12-3456789). Not every pay stub prints it, though. No federal law requires the employer’s EIN on every earnings statement, so if you can’t find it, you’ll need to check your W-2 or ask payroll.
What the Number Looks Like
The EIN always follows the same pattern: two digits, a hyphen, then seven digits (NN-NNNNNNN).1Internal Revenue Service. 21.7.13 Assigning Employer Identification Numbers (EINs) That format is your fastest visual cue. A Social Security number uses a three-two-four split (NNN-NN-NNNN), and state withholding account numbers vary by state and often mix in letters. If the nine-digit number you’re looking at breaks two-and-seven, it’s the EIN; if it breaks three-two-four, it isn’t.
The labels vary because payroll software varies. The most common abbreviation is FEIN (Federal Employer Identification Number), but the same number may appear as EIN, Federal Tax ID, Fed Tax ID, or simply Tax ID Number. All of these refer to the nine-digit number the IRS assigns to a business for tax reporting.2Internal Revenue Service. Employer Identification Number
Where To Look on the Pay Stub
Layouts differ, but the EIN is almost always grouped with the employer’s information rather than yours. Three common spots:
- The header, directly below or beside the employer’s legal name and business address. This is the most common location.
- The footer or tax-summary section, near the breakdown of federal income tax, Social Security, and Medicare withholdings.
- An employer information block — a boxed section that groups company name, address, phone number, and tax ID together, separated from your earnings data.
One quick check: if the nine-digit number is sitting in the section listing your personal details, it’s probably your Social Security number, not the employer’s EIN.
Telling the EIN Apart From Other Numbers on the Stub
A pay stub can carry several identification numbers, and the IRS recognizes several distinct Taxpayer Identification Numbers, each with its own format and purpose:3Internal Revenue Service. Taxpayer Identification Numbers (TIN)
- EIN: nine digits, NN-NNNNNNN. Identifies the business.
- SSN: nine digits, NNN-NN-NNNN. Identifies you.
- ITIN: nine digits, NNN-NN-NNNN, always starting with a 9. Used by certain nonresident and resident aliens who can’t obtain an SSN.
- State withholding account number: length and format vary by state and often include letters.
The two-seven split is the clean tell. Anything that breaks three-two-four is a personal identifier, not an employer identifier.
Why the EIN May Be Missing or Masked
Federal law doesn’t require the EIN on every pay stub. The Fair Labor Standards Act requires employers to keep records of your name, Social Security number, hours worked, pay rate, and deductions, but the employer’s EIN isn’t on that list.4U.S. Department of Labor. Fact Sheet #21: Recordkeeping Requirements Under the Fair Labor Standards Act (FLSA) Some state wage-statement laws add requirements, but many don’t specifically mandate the EIN. Whether the number appears on your stub depends largely on the payroll software your employer uses.
Even when it does appear, it may be partially hidden. IRS rules allow employers to truncate identification numbers on certain payee statements by replacing the first five digits with asterisks or Xs, leaving only the last four visible. Truncation is not permitted on Form W-2.5Internal Revenue Service. Truncated Taxpayer Identification Numbers (TTIN) So if your stub shows something like **-***4567, that’s a truncated EIN, and you’ll need the full number from another source.
Where Else To Find the EIN
If it’s not on the pay stub, or you can only see a masked version, these sources will have the full number.
Form W-2, Box b
The most reliable source is your Form W-2. Box b contains the employer’s full EIN in NN-NNNNNNN format, and employers can’t truncate it there.6Internal Revenue Service. 2026 General Instructions for Forms W-2 and W-3
Form 1099-NEC
If you’re an independent contractor rather than an employee, you won’t get a W-2. The payer’s EIN appears in the upper portion of Form 1099-NEC under “Payer’s TIN,” directly below the payer’s address and above your own taxpayer identification number.7IRS.gov. Form 1099-NEC (Rev. December 2026)
Your HR or Payroll Department
Often the fastest route. The EIN isn’t confidential — employers use it on publicly filed tax forms — and payroll staff can generally hand it over on request.
SEC EDGAR, if Your Employer Is Publicly Traded
For a publicly traded employer, the EIN appears on the cover page of the company’s annual 10-K under the heading “I.R.S. Employer Identification No.”8SEC.gov. Form 10-K You can search filings at sec.gov/edgar/search.
Common Reasons You’d Need It
Most people track down an employer’s EIN for one of these reasons:
- Filing a federal tax return. The W-2 already carries the EIN in Box b, but if you’re filing before the W-2 arrives or using a substitute form, you may need to pull it from a pay stub.
- Claiming the Child and Dependent Care Credit. If your child-care provider is an organization, you enter its EIN on Form 2441. If your employer furnished the care directly, you note the employer’s name and write “See W-2” instead.9IRS.gov. Instructions for Form 2441 – Child and Dependent Care Expenses
- Applying for a loan or financial aid, where lenders or aid offices sometimes ask for it to verify your income source.
- Confirming your employer’s legal identity, which matters if your company operates under a trade name different from its registered name.
If the EIN Turns Out To Be Wrong
An incorrect EIN on your W-2 can cause problems with your tax return and your Social Security earnings record. The IRS directs employees to start with the employer:10Internal Revenue Service. Topic No. 154, Form W-2 and Form 1099-R (What to Do if Incorrect or Not Received)
- Ask your employer to issue a corrected Form W-2c.
- If you haven’t received a corrected form by the end of February, call the IRS at 800-829-1040 with your name, address, Social Security number, and your employer’s name and address. The IRS will contact the employer on your behalf.
- If the corrected form doesn’t arrive in time to file, you can file using Form 4852, a substitute for Form W-2. You’ll estimate wages and withholdings, and a recent pay stub showing year-to-date totals or a prior year’s W-2 from the same employer can help you calculate them.11Internal Revenue Service. Using Form 4852 When Missing the Form W-2 or 1099-R
- If a corrected W-2 arrives later showing different amounts than what you filed, submit Form 1040-X to amend your return.
