Where to look in Pennsylvania
- Pennsylvania Department of State business search. Search by entity name or entity number.
- Sales tax license open data. Lists active licenses by legal name, trade name and address. Part of each license number is masked to reduce fraud, and there is no federal EIN column.
Pennsylvania numbers that get mistaken for an EIN
None of these is the nine-digit federal number unless the table says so. A bank, payroll company or client asking for your EIN wants the one the IRS issued.
| Used for | Issued by | The number |
|---|---|---|
| Company formation | Pennsylvania Department of State, Bureau of Corporations and Charitable Organizations | entity number |
| State income tax withholding | Pennsylvania Department of Revenue | Withholding ID, 8 digits (myPATH also shows an 11-digit Account ID) |
| Unemployment insurance | Pennsylvania Department of Labor and Industry | UC Employer Account Number, 7 digits |
| Sales tax | Pennsylvania Department of Revenue | Sales, Use and Hotel Occupancy Tax License |
Finding your own Pennsylvania company’s EIN
Start with the CP 575 letter the IRS sent when the number was issued, then a past federal return, your bank’s account paperwork and your payroll provider. If none of those has it, the responsible party can call the IRS and ask for a 147C letter. Do not apply again to replace a lost number: a second application creates a second EIN for the same company.
Finding another Pennsylvania company’s EIN
If you pay them, ask for a Form W-9: it is the normal way to get the number, and you need it for a 1099 anyway. Nonprofits are in the IRS Tax Exempt Organization Search, and public companies print theirs on SEC filings. For a private Pennsylvania company with no reason to give it to you, there is no free public source that is complete. To check a number you were given, see how to verify an EIN.
Pennsylvania EIN lookup questions
Does Pennsylvania have an EIN lookup?
The EIN is federal, so the IRS issues it and Pennsylvania does not. The Department of State says businesses are not indexed by tax or Federal I.D. number, and that its records do not reflect any tax information.
Is my Pennsylvania entity number my EIN?
No. The entity number comes from the Pennsylvania Department of State, Bureau of Corporations and Charitable Organizations and identifies your company in state records. The EIN comes from the IRS, and a bank or payroll company asking for one will not accept the state number.
I formed my Pennsylvania company but never got an EIN. What now?
Forming the company does not create an EIN. You apply separately with the IRS on Form SS-4, or a service like ours prepares and files it for you. If you might already have one, check first: applying again gives the same company a second number.
