What is Form PS-1583?

Form PS-1583, officially titled the Application for Delivery of Mail Through an Agent, is a required United States Postal Service (USPS) document. 


This form authorizes a Commercial Mail Receiving Agency (CMRA)—commonly referred to as a virtual mailbox provider—to receive and handle mail on behalf of an individual or business.


Completing Form PS-1583

For the form to be legally valid, all fields must be completed accurately and in full, as even minor errors may lead to rejection.


Since notarization is required, the notary must ensure the form is completed exactly as instructed.


Each section below includes clear guidance on what information must be entered.


Overview of Form PS-1583

1. Private Mailbox (PMB) Information

This section is not completed during the notary session, as these fields are filled in directly by the virtual mailbox provider.

  • Section 1a – Date PMB Opened: The date the mailbox was opened should be indicated here. This is not the date of notarization.

  • Section 1b – Date PMB Closed: This field may remain blank. In many cases, the virtual mailbox provider enters N/A in this section.

2. Commercial Mail Receiving Agency (CMRA) Place of Business Information

The Applicant must provide the address and mailbox number of the virtual mailbox they intend to use. This should be the address of the mailbox location for which the Applicant is registered.

In this section, the Applicant must indicate the purpose of the mailbox, specifying whether it is intended for personal use or business use.
