(a) The State unemployment compensation agency shall require, as a
condition of eligibility for unemployment benefits, that each claimant
for benefits furnish to the agency his/her social security number (or
numbers if he/she has more than one such number), and the agency shall
utilize such numbers in the administration of the unemployment
compensation program so as to associate the agency's records pertaining
to each claimant with the claimant's social security number(s).
(b) If the State agency determines that a claimant has refused or
failed to provide a Social Security Number, then that individual shall
be ineligible to participate in the unemployment compensation program.
(c) Any claimant held ineligible for not supplying a social security
number may become eligible upon providing the State agency with such
number retroactive to the extent permitted under State law. (Section
1137(a)(1)).
