Can a non-resident get a US EIN without an SSN or ITIN?
Yes. A non-US resident can get an EIN for a US LLC without an SSN or ITIN. You file Form SS-4 with the IRS by fax or mail and leave the responsible party's SSN/ITIN field blank, because the online EIN tool is the only channel that requires one. The IRS states about four business days by fax, and about four weeks by post.
Why the online tool blocks you
The IRS online EIN assistant asks the responsible party for an SSN or ITIN and cannot be completed without one. That is a limitation of the web form, not of the law. Non-residents apply through the fax or mail channel instead, where the number is not required.
How to file Form SS-4
Complete Form SS-4 with the LLC's legal name, US registered address, and the responsible party's name and foreign address. Write 'Foreign' in the SSN/ITIN box. Fax it to the IRS number for international applicants; the IRS states about four business days for the EIN to come back by fax.
