Apply Online
This Internet EIN (I-EIN) application opens another avenue for customers to apply for and obtain an employer identification number.  Once you have completed all necessary fields on the online form, preliminary validation is performed and will alert you to information IRS needs that you may not have included. An EIN will be issued after the successful submission of the completed Form SS-4 online. Please note that not all business entity types may use this method.

Apply by Mail or Telephone (Tele-TIN)
Use Form SS-4 (PDF) to apply for an EIN either by mail or by telephone. You can get an EIN within minutes by calling the Tele-TIN phone number for your state, or you can send the completed Form SS-4 to your local IRS service center to get your EIN by mail. You need a completed Form SS-4 to apply for an EIN by either method.

Other Important Information

• 3rd Party Authorization
  A 3rd Party designee must fill out the SEC. 6103(c) disclosure information at the bottom of the Form SS-4. The Form SS-4 must also be signed by the taxpayer for the 3rd Party designee authorization to be valid. The Form SS-4 must be mailed or faxed to the appropriate service center. A 3rd Party designee may call for an EIN, however a faxed Form SS-4 is still required. IRS assistors will take the information over the phone from the 3rd Party designee and ask the 3rd Party designee to fax the completed Form SS-4 to them (to the IRS assistor's attention) at an administrative fax number. After receiving the faxed Form SS-4, the EIN will be assigned and faxed back to the 3rd Party designee. The 3rd Party designee's authority terminates at the time the EIN is assigned and released to the designee.
• Consolidated Form SS-4 Applications by Fiduciaries
  A fiduciary representing 10 or more estates or trusts may submit a single Form SS-4 requesting a block of EINs. However, the trusts or estates must not be subject to employment or excise taxes. For more information, refer to Revenue Procedure 89-37, 1989-1.
• Taxpayer Representative Authorizations
  IRS can't issue EINs to third parties unless we have received Form 2848, Power of Attorney , at your local service center. Taxpayer representatives can get an EIN for their clients by sending (by FAX or mail) a completed Form SS-4 with Form 2848 attached, to the local IRS Service Center. IRS will contact the authorized taxpayer representative by phone or mail with the client's EIN. The Form 2848 applies only to releasing the EIN to the authorized taxpayer representative.
