To find your payroll number, check the header at the top of your most recent pay stub, open your profile in your employer’s payroll portal, or look at Box d on your W-2. It’s a short alphanumeric code your employer uses to identify you in its own records, and one of those three places almost always has it.
What You’re Looking For
A payroll number is an internal identifier assigned by your employer. Depending on the software your company uses, it may be labeled “Employee ID,” “File Number,” “Staff Number,” “Works Number,” or “Payroll ID.” It’s unique within your organization and has no meaning outside it.
It is not your Social Security number, and it is not the company’s Employer Identification Number. The SSN is your lifetime government identifier. The EIN is a nine-digit number the IRS assigns to the employer itself.1Internal Revenue Service.

On Your Pay Stub
Look at the top of the stub, in the same block that shows your name, address, pay period, and pay date. That’s where the payroll number sits.2Consumer Financial Protection Bureau. How to Read a Pay Stub – Building Blocks Student Handout The label varies by provider. ADP tends to use “File Number.” Gusto uses “Employee ID.” Whatever the wording, you’re scanning for a short alphanumeric code near your name.
Skip the earnings and deductions sections in the middle and bottom of the stub. Those cover gross pay, taxes, and net pay. The identifier lives in the administrative header. Your SSN may appear there too, but on modern stubs it’s usually partially masked, so a fully visible short code near your name is almost certainly the payroll number.
In Your Payroll Portal
If your employer uses a cloud platform like ADP, Workday, or Gusto, log in and open your profile. The tab is usually labeled “Personal Information,” “Profile,” or “My Info.” Your payroll number appears on the main profile screen near your name and job title. In Workday, it shows up under Profile then Personal Data, listed with your work contact information.
Every recent digital pay statement in the portal also carries the number in the same header position it would occupy on a printed stub. If the profile page isn’t obvious, open a pay statement instead.
On the mobile app, tap your profile icon or avatar and look for personal details. The ID is usually on the first screen rather than in a submenu. These platforms will ask you to complete multi-factor authentication before showing anything sensitive, so keep your verification method within reach.
On Your W-2
Your W-2 has a dedicated field for this: Box d, labeled “Control number.” The IRS instructions describe it plainly: “You may use this box to identify individual Forms W-2. You do not have to use this box.”3IRS.gov. 2026 General Instructions for Forms W-2 and W-3 Because it’s optional, some employers leave Box d blank and others fill it with your payroll or employee ID.
Don’t grab the number from Box a. That box holds your Social Security number, not your payroll identifier.3IRS.gov. 2026 General Instructions for Forms W-2 and W-3 Employers must issue a W-2 to any employee paid $600 or more in a year, or any amount if income, Social Security, or Medicare tax was withheld,4Internal Revenue Service. About Form W-2, Wage and Tax Statement so most employees will have this document to fall back on.
Other Places It May Appear
Your original offer letter or employment contract sometimes includes the payroll number, particularly when it was needed to set up direct deposit or benefits enrollment. Some employers also print it on physical ID badges used for building access or time clocks.
One document that won’t help is the Form I-9. It collects your legal name, date of birth, Social Security number, and immigration status, but it does not record any internal payroll identifier.5U.S. Citizenship and Immigration Services. 3.0 Completing Section 1 – Employee Information and Attestation
If You Still Can’t Find It, Ask HR
Contact your HR or payroll department through corporate email, an HR ticketing system, or your internal chat platform. Be ready to verify your identity with your full legal name, department, and often the last four digits of your Social Security number. Requesting a payroll number is routine, and payroll staff answer this question regularly.
Make Sure the Number Is Right
Once you have it, do a quick check. Compare the payroll number on your pay stub to the one on your W-2 at year-end. If they don’t match, or if Box d is blank when it wasn’t in previous years, flag it with payroll before the W-2 filing deadline. Errors in how your employer tracks your earnings can affect the record the Social Security Administration keeps under your name and SSN, and gaps in that record can reduce future retirement or disability benefits.6Social Security Administration.
