The national 800# is not the way to deal with this. Walk it in to your local office. If you have a checking account bring a cancelled check. If you have a saving account bring the routing # and a bank statement. If you want a different set up, bring the pertinent info.

You can get lucky with the 800#, but it is very unreliable.

If you have access to make changes online at the SSA website, that might work provided it is one simple change.

And, yes, I'm officially a broken record.
