Do I need to include my PMB number when I give out my address?

Yes. Please always include your PMB number whenever you give out your address.

Per the US Postal Service, mail sent to an addressee at a CMRA (Commercial Mail Receiving Agency) must include either the PMB identifier or the #, followed by the appropriate private mailbox number. Think of it as a suite number within a large business park. Without this number, your address is not complete and it is much more likely mail will be returned or misrouted.
