Question about social security cards

Does anyone know if I needed my social security card right away and can’t find it… would I be able to go to social security office and order one and get proof or receipt that I have one on the way and use the proof or do I still have to wait to use it…

Depends on where you are trying to use it at, some places will accept the letter and some places want an actual card

Echoing the previous, some places may not accept the letter. My state uses a certified stamp on it so it will be accepted without issue though so might be worth calling the place you need it for beforehand to find out if they’ll accept the letter from the social security office.
