If you need to find the name or physical address of a post office box's owner, you need to submit the right form to the post master of the post office box's physical location. The person renting the post office box is entitled to their privacy, so you may find your local post office reluctant to release the information to you without a subpoena.
Filling Out the Form
If the owner of the post office box needs to be located for legal reasons, the seeker can fill out the United States Postal Service Change of Address or Boxholder Request Format form. You'll need the names (if known) of all parties in the litigation, the docket or identifying number for the case, the capacity of the person seeking the information and that of the post office box owner, such as defendant or witness. If you are representing yourself in a legal case, list yourself as the party representing self. The post office doesn't charge for this information.
Fill in the form as completely as you can. The post office will contact you to fill in any missing information, but that will lead to a delay in your request.
Find the Box
You can find the box itself through the post office or searching online. You will need both the post office box number and the zip code to search for the post office box. When you know the location of the post office box, you can mail your Boxholder Request Format form to the post master of that post office. This can help speed up the reply time.
Post Office Policy
According to USPS policy, the response to requests for customer names and addresses varies depending on who is requesting the information. Subsection D of the Requests for Employee or Customer Information section outlines how requests are to be handled.
Individuals participating in the legal process must fill out the Change of Address or Boxholder Information form with all relevant information. A general, state, or local government employee must provide their request in writing and certify the information is needed to perform their jobs. Information about a post office box owner's mailing address will also be provided to a judge, court clerk, or jury commissioner free of charge for jury service notices. Again, this request must be made in writing.
According to the Post Office Freedom of Information Act FAQs, you can expect a reply to your request in writing within 20 working days. That may be extended by another 10 days if you submitted the request to a post office other than the one where the box is located. If you haven't received a response within 20 days, call the post master of the station where you submitted your request to follow up. If a request for information about a box owner is denied, you will need a subpoena or court order.
When a subpoena or court order requests the post office box owner's name and/or address, the information will be released only if the post office's counsel agrees that releasing the information is essential to the case.
