USPS Form 1583 authorizes a separate USPS-registered mailbox to receive mail for you. Complete the current form and identification checks before relying on the mailbox.
Prepare the current application
Use the form supplied for your current mailbox arrangement. Enter the applicant, address and business information accurately. Ask the provider how separate adults, businesses and any minors should be recorded; do not assume one signature authorizes unrelated recipients.
Match the required identification
The form distinguishes photo identification from address identification. Read the accepted-document lists and check that names and addresses match the application. Two documents are not sufficient merely because one happens to have a photograph; each must satisfy the designated category.
Sign through an accepted process
Follow the form’s witnessing instructions, such as signing before a notary public. If using a remote process, confirm the provider’s supported procedure before signing. An uploaded signature image alone should not be treated as completed identity verification.
Keep the record current
Notify the provider when application information or identification changes and follow the current USPS update requirements. Do not treat the original authorization as permanently valid regardless of later changes. Save the accepted copy and confirmation in your records.
Resolve a rejected document
Ask support which field or identification category failed. Send replacement identity documents only through the provider’s designated secure process. Mail authorization does not prove Florida domicile or satisfy a bank’s residential-address requirement.
