Section 37.11(c) of the DHS final rule allows states to accept several types of documents as proof of social security number: a social security card, a W-2 form, an SSA-1099 form, a non-SSA-1099 form, or a pay stub bearing the applicant's name and SSN. However, states are not required to verify the validity of these documents directly with their issuers (e.g. with the employer that issued a W-2 form or a pay stub). Instead, the DHS rule requires the states to verify the validity, and its match with the name given, of the social security number itself, via electronically querying the Social Security On-Line Verification (SSOLV) database managed by the Social Security Administration.
