Hawaii EIN Lookup
Last updated November 5, 2026 · Written by the EIN Registration filing team
Look up a Hawaii company
Hawaii 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 Hawaii 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 Hawaii
- Hawaii Business Express. Search by business name. Use it to confirm the company's exact name and status.
- Hawaii Tax Online: Search Tax Licenses. The Department of Taxation says it searches names, Hawaii Tax ID numbers and status for taxpayers with a permit, license or account. It reveals the Hawaii Tax ID, not the federal EIN.
- Hawaii Tax IDs start with a two-letter tax type code, as in GE-987-654-3210-01, so they are easy to tell apart from an EIN.
Hawaii 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 | Hawaii Department of Commerce and Consumer Affairs, Business Registration Division | file number |
| State income tax withholding | Hawaii Department of Taxation | Hawaii Tax ID, written WH-###-###-####-## for withholding |
| Unemployment insurance | Hawaii Department of Labor and Industrial Relations | UI account number |
| Sales tax | Hawaii Department of Taxation | General excise tax license |
Finding your own Hawaii 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 Hawaii 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 Hawaii 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.
Hawaii EIN lookup questions
Does Hawaii have an EIN lookup?
The EIN is federal, so the IRS issues it and Hawaii does not. Hawaii Business Express 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 Hawaii file number my EIN?
No. The file number comes from the Hawaii Department of Commerce and Consumer Affairs, Business Registration 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 Hawaii 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.
