So I don't know if this is just a local SSA office thing, but here you can't actually go in without making a physical appointment since COVID (same as with the DMV), at least when we did it back in 2023. Every single time we needed to update a record we went in. It used to be walk-ins (but you were crazy to do it unless it was on a Wed), but I have to tell ya the old office was a hole in the wall mess. Eventually they changed it to a big new building and when we arrived there were 20 windows, but literally only ONE employee and then a security guard. It seemed hilarious that an appointment was needed because there was no one there that needed help. Took all of 5 minutes.
I have heard about some kind of directive that has been mentioned in the thread. An article or two and also from some lawyers mentioning it online, but I don't think anything officially yet? Still, I was such a stickler about making sure stuff got done in-person and not waiting around, going into the SSA is a good idea to update whatever is needed. The employee took a scan of the certificate as well.
