Your USGM address is not a PO Box. It's a real, street address. A PO Box has many limitations of where it can be used for example, many government entities and banks won't accept a PO Box address, but many of our customers use their USGM address for these purposes.
The Stable address can be used with all government entities, and many of our customers use it to file taxes, sign up for new vendors, register for payroll/ benefits, and much more.
If its being flagged by some institutions, we recommend doing a few things:
Reformat the address without the "#" sign. Some banks associate this sign with a P.O. Box, which your address is not. Instead, try using your unit number with "Suite," "STE," or with just the number.
Some banks may not accept a CMRA address (commercial mail receiving address- which all virtual mailboxes are). In that case we recommend using a residential address or registered agent address when opening the account. And then using your USGM address as the mailing address. That ensures all your mail always arrives at your USGM address.
