The Social Security Administration is revising proposed changes that would have required some beneficiaries to prove their identity in-person when seeking services.

Officials said in a statement Wednesday that they are exempting people who apply for Medicare and disability benefits, as well as supplemental income help for the poor, from having to prove their identity in-person at a social security office if they are unable to use the agency’s online system.

They also announced they are pushing back the start of the new policy by two weeks, to April 14.

The new rules, which were first announced last week, were met with concerns from advocates for seniors and people with disabilities, as well as lawmakers. Dozens of Democratic members of Congress sent a letter to agency leaders last week asking them to reconsider the change because it would “create additional barriers” for people seeking services — “particularly for those who live far from an office.”
