I guess I'm going to have to ask for clarification as to which country you're in.

In the US, the USPS runs the Address Management System used as (basically) the canonical source of mailing addresses used by most if not all couriers and you can reach your "local" AMS office by way of https://postalpro.usps.com/ppro-tools/address-management-sys... to inquire about your address. This is commonly done during new construction, subdivisions, and so on but typically starts with the postmaster in your local office forwarding onto AMS for edits.
