If you’re filling out a tax form, applying for a loan, or opening a bank account, you may be asked:
“Where can I find my Tax Identification Number (TIN)?”
A Tax Identification Number (TIN) is a unique number used by the IRS to track your personal or business tax obligations. Depending on your situation, your TIN might be your Social Security Number (SSN), Employer Identification Number (EIN), or Individual Taxpayer Identification Number (ITIN).
Common Types of Tax Identification Numbers
Here’s a breakdown of the most common types of TINs:
- SSN (Social Security Number) – for individuals
- EIN (Employer Identification Number) – for businesses
- ITIN (Individual Taxpayer Identification Number) – for non-U.S. residents or those not eligible for an SSN
Where Can I Find My TIN?
1. On Tax Documents
Your TIN can usually be found on documents like:
- IRS tax returns (Form 1040, 1120, etc.)
- W-2 or 1099 forms
- IRS Notices or Letters
- EIN confirmation letter (for businesses)
2. On Financial Documents
You might also find your TIN on:
- Payroll documents
- Bank statements
- Official business registration paperwork
How to Find Your TIN Based on Type
For Individuals (SSN):
- Check your Social Security card
- Look on your W-2 or tax return
- Contact the Social Security Administration (SSA) if lost
For Businesses (EIN):
- Refer to your IRS EIN confirmation letter
- Look at your business tax filings
- Call the IRS Business & Specialty Tax Line at 800-829-4933
For Non-U.S. Residents (ITIN):
- Find it on your IRS ITIN approval letter
- Check past Form 1040 tax returns
- Contact the IRS if you’ve lost your ITIN documentation
What If I Still Can’t Find My TIN?
If you can’t locate your TIN through your documents:
- Individuals should call the SSA (for SSN) or IRS (for ITIN)
- Businesses can call the IRS for a copy of their EIN (you may need to verify your identity)

Start by checking your tax returns, payroll forms, or IRS correspondence. If you’re still unsure, the IRS or SSA can help you retrieve it securely.
