International EIN phone number: +1-267-941-1099 Call +1-267-941-1099, Monday through Friday, 6:00 a.m. to 11:00 p.m. Eastern time. The number is not toll-free. It is for an eligible principal business created or organized outside the United States and U.S. territories—not a foreign-owned U.S. LLC.

Who can use the international EIN phone number?

Under the current SS-4 telephone instructions, the phone option requires the applicant to have no legal residence, principal place of business, or principal office or agency in the United States or U.S. territories. The IRS March 2026 processing update adds the operational classification test: the principal business must be created or organized outside the United States and U.S. territories.

A U.S.-organized LLC cannot use this phone route A Delaware, Wyoming or other state-organized LLC is a domestic case even when its responsible party and operations are abroad. IRS personnel are instructed to direct that caller to another EIN application method. Use the fax or mail route that matches the current public instructions.

Prepare the complete form before calling

  • Entity legal name and trade name, if any.
  • Mailing address, physical address and principal business location.
  • Responsible party’s full name and the correct line 7b entry.
  • LLC member count and U.S.-organization answer on lines 8a–8c.
  • Entity type on line 9a and the real reason for applying on line 10.
  • Start date, accounting-year closing month, employee estimates and principal activity.
  • Prior-EIN answer on line 18.

The IRS recommends completing Form SS-4 first because its representative uses the form information to establish the account and assign the number.

Who should make the call?

The caller must be authorized to receive the EIN and answer questions about Form SS-4. The responsible party can call. A third party can call only with valid authorization through the completed Third Party Designee section and signature area.

The SS-4 instructions say a third-party designee’s authority ends when the EIN is assigned and released to that designee. It is not continuing authority over the entity’s tax account.

What happens during and after the call

  1. The representative asks for the information from Form SS-4 and may clarify entries.
  2. If an EIN is assigned, write it in the upper-right corner of your form.
  3. Sign and date the retained form and keep it in the entity’s permanent records.
  4. If the representative asks for it, send the signed Form SS-4—including third-party authorization—by the address or fax number provided within 24 hours.

These are the steps stated in the IRS Instructions for Form SS-4. Assignment depends on the information supplied and IRS processing; this guide cannot guarantee an EIN during a call.

Keep a requested 24-hour SS-4 handoff on track

If the IRS requests your signed SS-4, keep the destination and 24-hour handoff together. This is a follow-up to an eligible international telephone application, not an invitation to apply again. A U.S.-organized LLC cannot use this telephone application route.

1. Before ending the call

Note whether an EIN was actually assigned. If the representative requests the signed form, write down the exact destination and sending method they provide. Read the instructions back and clarify anything you did not hear.

2. Hand over the request

The IRS instructions say to mail or fax the signed SS-4, including any third-party designee authorization, within 24 hours if requested. Give the person handling it the request time with its time zone, the destination and a clear deadline. Do not treat 24 hours as a business-day allowance.

3. Keep the record together

If an EIN was assigned, write it in the upper-right corner of the form, sign and date it, and keep the copy. Our additional recordkeeping suggestion: keep the request notes and sending evidence with that copy. Sending evidence does not prove IRS receipt or processing.

A fictional handoff across time zones

An authorized caller for an eligible business organized outside the U.S. receives a request at 16:10 UTC on Wednesday, November 4. A 24-hour interval ends at 16:10 UTC on Thursday, November 5. Both people record that same instant and convert it to their own calendar time; the sender aims to act earlier. This is a coordination example, not an IRS extension or a definition of when a filing is considered received.

The caller passes along the representative’s actual destination, the signed SS-4 and any designee authorization. The sender returns the sending evidence. No sample EIN, address or fax destination is supplied here to copy accidentally.

No form requested? The 24-hour instruction is conditional. Do not send an extra SS-4 merely because you read this checklist. If the call ends with assignment or instructions unclear, keep that uncertainty in your notes and clarify it through the IRS before treating the application as completed or starting another one.

Open the private phone handoff record (TXT). Save and complete it in your own records; do not send it to EINForeigner. It is our optional coordination aid, not an IRS form or authorization.

Section added November 4, 2026. IRS requirements checked against the SS-4 telephone instructions on that date. Read-back, shared time-zone notes and sending-evidence organization are our practical suggestions.

Five avoidable call problems

  • Calling without a fully prepared SS-4.
  • Using an unauthorized assistant who cannot legally receive the number.
  • Guessing line 9a tax classification during the call.
  • Confusing a registered-agent address with the principal place of business.
  • Calling repeatedly or applying through another method for the same entity.

One EIN per responsible party per day

The IRS limits issuance to one EIN per responsible party per day across online, telephone, fax and mail applications. The limit is not reset by changing the application method.

If phone is not practical

An international applicant can also submit Form SS-4 by fax or mail. The current IRS page lists 855-215-1627 when the international-route fax is sent within the United States and 304-707-9471 when sent from outside the United States. Recheck routing before filing and use only one method for the entity.

International EIN phone questions

Is 267-941-1099 toll-free or open on weekends?

No. The IRS lists this as a non-toll-free number, available Monday through Friday from 6:00 a.m. to 11:00 p.m. Eastern time. Use Eastern time, not your local time abroad, when planning the call.

Can I call to apply again if I already faxed Form SS-4?

Do not start a second application to work around a delay. The IRS says to use only one application method per entity. Follow the faxed SS-4 status checklist and resolve whether an EIN was already assigned before changing methods.

Can a foreign owner call for a Delaware or Wyoming LLC?

Not to obtain an EIN through this telephone application route. The IRS March 2026 update treats a U.S.-organized LLC as a domestic case even if its owner is abroad. Check the Form SS-4 fax routing guide for the applicable alternative.

Official IRS sources Phone conditions, hours, authorization and after-call instructions come from the Instructions for Form SS-4. The U.S.-organized entity restriction appears in the March 2026 IRS procedural update. The number and alternate routes are also listed on the IRS Employer identification number page.
