South Carolina EIN Lookup

South Carolina only allows its search on its own site, so this opens in a new tab. It finds the company, not usually its EIN.

South Carolina 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 | South Carolina Secretary of State | entity ID |
| State income tax withholding | South Carolina Department of Revenue | Withholding account number, 9 digits |
| Unemployment insurance | South Carolina Department of Employment and Workforce | Employer Account Number (EAN) |
| Sales tax | South Carolina Department of Revenue | Retail license |
Finding your own South Carolina 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 South Carolina 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 South Carolina 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.
South Carolina EIN lookup questions
Does South Carolina have an EIN lookup?
The EIN is federal, so the IRS issues it and South Carolina does not. South Carolina Business Entities Online finds a company by business name. Do not count on it for the federal number. The reliable sources are the company itself, on a Form W-9, or your own IRS paperwork if the company is yours.
Is my South Carolina entity ID my EIN?
No. The entity ID comes from the South Carolina Secretary of State 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 South Carolina 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.
