Faxing Form SS-4 is the fastest method for non-residents without an SSN or ITIN to obtain an EIN. Processing typically takes 1-2 weeks compared to 4-6 weeks for mail applications.
Complete Form SS-4 accurately, then fax it to the IRS at (855) 641-6935 if submitting from within the US, or (304) 707-9471 if faxing from outside the US.
The IRS will process your application and fax back your EIN assignment notice (Form CP 575) to the fax number you provide on Line 4 of Form SS-4.
Within US: (855) 641-6935. Outside US: (304) 707-9471. Using the correct number ensures proper routing and faster processing.
Expect 1-2 weeks for fax applications. Significantly faster than mail processing which takes 4-6 weeks.
Include a valid fax number on Line 4 where the IRS can send your EIN confirmation. This can be your fax number or a service number.
The IRS will fax back Form CP 575, your official EIN confirmation letter. This serves as proof of your EIN assignment.
