Yes.

Residents of a few metros (New York City, Philadelphia, Orlando and the Twin Cities) must use a dedicated Social Security Card Center for card-only services.
Can I apply for replacement cards or retirement benefits online instead?
Yes. In most cases, U.S. citizens can request a replacement Social Security card, apply for retirement or disability benefits, and check benefit verification letters online at ssa.gov without visiting the Union office in person. SSA says the online route is the fastest way to get a replacement card; offices cannot print one on the spot.
