Michigan EIN Lookup
Last updated November 5, 2026 · Written by the EIN Registration filing team
Look up a Michigan company
Michigan only allows its search on its own site, so this opens in a new tab. It finds the company, not usually its EIN.
No EIN yet for your Michigan business?
We file the SS-4 for you. EIN typically emailed in 2 to 4 business days (about 11 by fax).
Where to look in Michigan
- LARA Corporations Division business entity search. Search by entity name, individual name, ID number or filing number.
- Michigan Treasury works the other way round: its forms use the nine-digit FEIN, or a Treasury-issued TR number, as the Business Account Number. So your own Treasury paperwork is a good place to find your EIN, even though LARA's records are not.
Michigan 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 | Michigan Department of Licensing and Regulatory Affairs (LARA), Corporations Division | customer ID number |
| State income tax withholding | Michigan Department of Treasury | Your federal EIN (Treasury business account number) |
| Unemployment insurance | Michigan Unemployment Insurance Agency | Employer Account Number (EAN) |
| Sales tax | Michigan Department of Treasury | Sales tax license |
Finding your own Michigan 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 Michigan 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 Michigan 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.
Michigan EIN lookup questions
Does Michigan have an EIN lookup?
The EIN is federal, so the IRS issues it and Michigan does not. LARA's own Michigan Business Roadmap says EINs should not be provided to the Corporations Division, and the ID number it assigns is not a federal tax number.
Is my Michigan customer ID number my EIN?
No. The customer ID number comes from the Michigan Department of Licensing and Regulatory Affairs (LARA), Corporations Division 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 Michigan 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.
