How the IRS Issues and Recognizes Tax Exempt Numbers
The IRS assigns an Employer Identification Number to almost all new nonprofits immediately upon application. This EIN serves as the primary tax exempt number for most organizations, even before final exemption determination.
If your organization applies for 501(c)(3) status, the IRS sends a separate tax exempt number on the approval letter once your application is granted. This number usually starts with 9 and is linked specifically to your federal exemption status.
Understand that the EIN alone does not prove charitable status, while the 1023 tax exempt number confirms that the IRS has reviewed and accepted your application.
Verify Your Tax Exempt Status with Official IRS Resources
Start by checking the IRS Tax Exempt Organization Search using your organization name or EIN to confirm active status and view your tax exempt number.
Download copies of your determination letter and business documents that display your tax exempt number clearly for records and for presenting to banks or donors.
Contact the IRS Business and Specialty Tax Line when you need help interpreting which number to use on specific forms or if you see mismatched information.
State and Local Requirements for Tax IDs and Exemptions
Many states require a state tax ID or registration number before you can receive tax exempt treatment on state purchases or sales.
Review state specific forms carefully because the display format and labeling of the tax exempt number can differ significantly from the federal EIN or exemption number.
Verify rules for charitable resale certificates, property tax exemptions, and sales tax collection responsibilities using your state revenue agency resources.
Common Uses and Practical Management of Your Tax Exempt Number
Use your tax exempt number when opening bank accounts, contracting with vendors, filing annual returns, and applying for grants or funding.
Train staff to store the number securely, limit public posting of the full number when unnecessary, and update records promptly when information changes.
- Confirm the correct number on all official documents before submission.
- Keep copies of determination letters and renewal notices in a secure location.
- Check database listings regularly to ensure your organization remains visible and accurate.
- Use the federal EIN for general business purposes and the specific tax exempt number where exemptions are legally required.

FAQ
Reader questions
What do I do if my tax exempt number is not showing up in the IRS search?
Double check the exact legal name and apply for a new EIN if necessary, then contact the IRS for assistance in locating your exemption record.
Can I use my EIN instead of the 1023 number when applying for grants?
Yes, many grant applications accept the EIN, but foundations that require proof of federal tax exempt status will specifically ask for the 1023 tax exempt number.
Why does my state tax ID look different from my federal tax exempt number? States use their own numbering format and issue separate identifiers for state tax purposes, which appear distinct from the federal EIN or exemption number. Do employees need to know the full tax exempt number for daily tasks?
Share the EIN for routine business use and restrict access to sensitive exemption numbers while training staff on when each identifier is required.
