In an effort to limit fraudulent claims, the Social Security Administration will impose tighter identity-proofing measures, requiring millions of recipients and applicants to visit agency field offices rather than over the phone.

Beginning March 31, New Yorkers will no longer be able to verify their identity to the SSA over the phone, and those who cannot properly verify their identity over the agency’s “My Social Security” online service will be required to visit an agency field office in person to complete the verification process.

The change will apply to new Social Security applicants and existing recipients who want to change their direct deposit information.

Retiree advocates warn that the change will negatively impact those with disabilities, who live far from SSA offices and have limited internet access.

The plan also comes as Elon Musk’s Department of Government Efficiency directed the agency to shutter dozens of Social Security offices throughout the country and lay off thousands of workers.
