Having a valid and verifiable address in the United States is a strategic necessity for thousands of people who operate globally. From opening a bank account to registering an LLC or receiving official correspondence, having a legally supported address can make the difference between moving forward or being left out of the system.
Updated July 2026.
For those who do not physically live in the US, virtual lockers represent a great solution. But it is not enough to have an address: you need to be able to demonstrate that you have the legal right to use it. This is where 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 operating address in Delaware.
What is USPS Form 1583?
The 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 required to activate your address, but can become a tool to officially demonstrate your link to a US mailing address
Many of our clients have used this document to facilitate processes such as:
-
Opening personal or business bank accounts in the US
-
Registration of companies (LLC or C-Corp) in states like Delaware
-
Identity verification before financial, commercial and government platforms
-
Justification of postal address before customs services or logistics providers
