ITIN vs SSN vs EIN

ITIN, SSN, and EIN are three different US tax IDs. Most non-resident Wyoming LLC owners need EIN only. This guide clarifies each.

Answer

SSN (Social Security Number) is for US citizens and lawful US workers. ITIN (Individual Tax Identification Number) is for non-residents who need to file US personal taxes. EIN (Employer Identification Number) is for business entities. Non-resident Wyoming LLC owners need EIN (for their LLC). They typically do NOT need SSN (you cannot get one as a non-resident anyway) or ITIN (only needed for PayPal personal verification or filing personal US Form 1040-NR).
