Where to look in New York
- New York Department of State business entity database. Search by entity name or DOS ID.
- Registered Sales Tax Vendor Lookup. Lets a seller check that a business giving it an exemption certificate is an active, registered sales tax vendor.
- New York's Tax Department says a business's federal EIN, or a temporary New York ID if it has none, appears on its sales tax Certificate of Authority, which must be displayed at each place of business. For a retailer, that certificate is the likeliest place to see the number in person.
New York 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 | New York Department of State, Division of Corporations | DOS ID number |
| State income tax withholding | New York State Department of Taxation and Finance | Your federal EIN (withholding identification number, your EIN plus any suffix and check digit) |
| Unemployment insurance | New York State Department of Labor | UI employer registration number, 8 digits (7 digits plus a check digit) |
| Sales tax | New York State Department of Taxation and Finance | Certificate of Authority |
Finding your own New York 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 New York 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 New York 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.
New York EIN lookup questions
Does New York have an EIN lookup?
The EIN is federal, so the IRS issues it and New York does not. The fields the Department of State publishes, and the state's open dataset of the same records, include no EIN or tax ID.
Is my New York DOS ID number my EIN?
No. The DOS ID number comes from the New York Department of State, Division of Corporations 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 New York 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.
