Applying for an EIN Without an SSN or ITIN
If you have no SSN, no ITIN and your business is or will be located in the U.S., you can still apply for a business EIN. However, the process is more complicated because you are not allowed to apply for the EIN online. To get your business EIN as a foreign person, you need to fill out IRS Form SS-4, Application for Employer Identification Number (EIN). We have an entire blog post that provides step-by-step instructions for filling out Form SS-4.
You cannot file this form online (unless you have an ITIN, as discussed above). This means you'll need to choose whether you want to file the SS-4 form by phone, fax or mail. According to the IRS Form SS-4 instructions, you have to choose only one application method, and you cannot file the form by multiple methods.
Since each method is slightly different, you have to decide whether to apply by phone, fax or mail based on what will work for your situation.
Phone: Only international EIN applicants can receive a business EIN by phone. According to the IRS instructions for Form SS-4: "If you have NO legal residence, principal place of business, or principal office or agency in the U.S. or U.S. possessions, you may call 267-941-1099 (not a toll-free number), 6:00 a.m. to 11:00 p.m. (Eastern Time), Monday through Friday, to obtain an EIN."
Fax: There is a special fax number to use if you want to apply for your business EIN by fax. Send the relevant IRS form to this fax number: 304-707-9471. If you apply by fax, you will generally receive your business EIN within four business days.
Mail: If you prefer to file the IRS Form SS-4 by mail, use this address for international applicants (who do not have any legal residence, principal office or principal agency in any state or international U.S. territory):
Internal Revenue Service

If you apply by mail, it might take several weeks for your business EIN to arrive. You also have another option when it comes to obtaining an EIN as a foreign entity. Working with the IRS can be complicated, especially if you are based outside the U.S. This is why the IRS lets you have the option to work with a third-party designee on your behalf.
If you want a third-party designee (like an attorney) to be allowed to talk to the IRS on your behalf, you can designate this on the IRS SS-4 form. Your third-party designee will be allowed to receive your new business EIN on your behalf, which can be helpful in working through the IRS application process to avoid any errors or delays.
