A USPS 1583 gives us permission to accept and handle mail under your or your business’s name. We’re required by law to have a signed copy of this form on file in order to ensure that a real person or entity is linked to a Stable mailbox.
When you set up a Stable address, we’ll pre-fill this form for you!
This form is required regardless of whether you set up a mailbox for an individual or a business — plus if you’d like to add additional business recipients at any point in the future, we’ll need corresponding USPS 1583 forms for every new legal entity!
You can download the USPS 1583 form here for reference.
