do I have to call to schedule an appointment or can I do through here

You can walk in. You walk in to a kiosk, type your ss# and get a number. They DO NOT DO Social Security cards here. You must go to 123 William Street for a card. ( Bring photo ID) to both places. At 126th you can apply for a claim, check on a claim and get a free copy of your award letter. At the card center they confirm your identity and validate your mailing address and mail the card in 7-10 biz days.

I am trying to get a new card but I have gone there more. They gave me application and ask to mail it I. Its been 1 year and I still don't have a card what I do

I really don't know call and ask

Good question i don't know call and find out
