For folks who have a PO Box I'm dropping a friendly PSA to let everyone know that some POs will also give you a physical address which you can use should you have a vendor who doesn't ship to PO Boxes for some reason or if you need a physical address for document forging etc.
First see if your PO is on this list https://ribbs.usps.gov/mtcsa/documents/tech_guides/mtcsa.txt Use ctrl+f and look for your PO Box zip code
If your ZIP code is on the list then bring this form https://ribbs.usps.gov/mtcsa/documents/tech_guides/PBSACustomerAgreement.pdf completed to the PO. The service isn't well established so they may look at you funny at first but should be able to figure it out.
Once that's all set send a few tests to your new physical address and you should be good to go.
Thanks, this is useful.
