Some financial institutions balk when you go in with a PO Box address.
I found this comment on Ken’s website. Credit for this goes to a poster over there named midas89:
Beth, you probably already know that USPS allows Street Addressing for PO Boxes. Example: You have PO Box 5555 located at the USPS at 100 Main Street, Anytown, CA. After you sign up for USPS Street Addressing for your PO Box, you can have U.S. Mail (and UPS & FedEx, etc.) addressed to: Your Name, 100 Main St. Unit 5555, Anytown, CA. (You can also substitute Unit with #.)
On my DL, I changed the PO Box address to the USPS Street Addressing Address, so people see it’s a street address…and they might not instantly recognize that the street address really resolves to the Post Office. (Now, of course, a bank, etc. that checks the address will have access to a database that informs them it’s a “Commercial Mail Receiving Address.”)
I have not personally sought to apply for street addressing for my USPS PO Box because I was unaware, prior, such a thing even existed. Surely hope poster midas89 is correct. We shall see.
Apparently midas89 is spot on, albeit with one or two wrinkles. There is much more information on this topic here:
Ongoing research indicates this USPS feature might have application in the MS world. Sorry, I do not have the details.
