Is Your EIN Active?
An Employer Identification Number (EIN) is a unique nine-digit number issued by the IRS to businesses for purposes like tax reporting. Applying for an EIN directly through the IRS is typical, and there is no cost to apply. An EIN becomes the permanent federal taxpayer identification number for that business once assigned.
Businesses require EINs for:
- Paying taxes
- Establishing business credit
- Opening business bank accounts
An EIN does not expire and cannot be reused, even if the business closes temporarily or the EIN is not used for returns. The IRS cannot cancel an EIN, but you can request the IRS to close the account if it’s no longer needed, making the number "inactive."
How to Verify Your EIN
To check if an EIN is valid, call the IRS at 800-829-4933. All business EINs are public information. To verify a company’s EIN:
- Search SEC filings. The EIN is listed under the title "I.R.S. Employer Identification Number" on recent 10-Q or 10K forms.
- Ask the company directly.
Businesses located in the US can apply for an EIN online, restricted to one EIN per responsible party per day. Your application may be denied if your business name closely resembles another.
EIN Longevity
Once issued by the IRS, an EIN does not expire and remains with the entity forever. To close an EIN account, contact the IRS and provide a reason for the closure. Include a copy of the EIN Assignment Notice. Business owners typically need an EIN to file tax returns, apply for business permits and licenses, and conduct other official business activities.
