If you applied and are waiting
| How you applied | When to expect it |
|---|---|
| Online | In the same session, on the confirmation screen |
| Fax | About 11 business days, sometimes longer |
| About 4 weeks |
Checking your EIN application status explains what to do if that time has passed. If you have the number but it does not work yet, see new EIN not active yet.
If you never had one
You apply on Form SS-4. How to apply for an EIN covers the checks and steps, and how to get an EIN for an LLC covers LLCs.
If you need someone else’s number
The IRS will not give out another business’s EIN. Ask them for a Form W-9, or try our free EIN lookup, which searches the public records where EINs appear.
Quick answers
Can I get my EIN number online?
Only if you are applying for a new one. The IRS has no online way to look up a number already issued, so a lost EIN means checking your records or calling.
Can the IRS give me my EIN over the phone?
Yes, once they confirm you are an authorized person for the business, such as the responsible party or an officer.
Who can call the IRS for my EIN?
An authorized person for the business, such as a sole proprietor, a partner, a corporate officer or a trust's fiduciary.
Is a 147C letter the same as a CP 575?
No. The CP 575 is issued once when the EIN is assigned. The 147C is the replacement letter that confirms the number later.
