Having a valid, verifiable address in the United States is a strategic necessity for thousands of people operating globally. From opening a bank account to registering an LLC or receiving official correspondence, having a legally backed address can make the difference between moving forward and being left out of the system.
For those who do not physically live in the US, virtual mailboxes are a great solution. But having an address is not enough: you need to be able to prove that you have the legal right to use it. This is where the USPS Form 1583 comes in, and with MDE you can turn it into a notarized public certificate, backed by your name and linked to our operational address in Delaware.
What is USPS Form 1583?
Form 1583 is a document issued by the United States Postal Service that authorizes a CMRA (Commercial Mail Receiving Agency) —such as MDE— to receive mail on your behalf. This form is not mandatory to activate your address, but it can become a tool to officially prove your link to a postal address in the US.
Many of our clients have used this document to facilitate processes such as:
-
Opening personal or business bank accounts in the US
-
Registering companies (LLC or C-Corp) in states such as Delaware
-
Verifying identity with financial, commercial and government platforms
-
Justifying a postal address with customs services or logistics providers
