Social Security says it will delay in-person ID verification. Advocates say that's not enough.

A new Social Security policy that requires in-person identity checks for millions of new and existing beneficiaries will delayed by two weeks, the agency said on Wednesday. 

The two-week delay to the policy, which had sparked a furor among seniors advocacy groups, lawmakers and beneficiaries, means  the in-person verification requirement will now begin on April 14, rather than March 31 as originally planned, the Social Security Administration said. 

In addition to delaying the policy by two weeks, the SSA also said it was exempting Medicare, disability and Supplemental Security Income applications from in-person ID verification. Supplemental Security Income is a program for low-income seniors and disabled people.
