A car ran into my mailbox so do not have a mailbox off of the street. Can I pick up my mail at the boys town office?

The USPS has a form that you can complete stating your issue and when you expect to have it corrected, in the meantime the USPS can hold your mail at your local postal office for you go come in and pick it up.

This is a community sourced question platform. You should probably call the office for a niche questions about mail.
