Keep in mind that completing that form does not guarantee that you will be given the box holder’s information, and if you incorrectly fill out the form, the post office is not required to complete your request. If the request lacks any of the required information or a proper signature, the custodian must return the request to the agency specifying the deficiency in the space marked "other".” There is also another “boxholder request” form, which is available on the United States Post Office website. According to the USPS website, “Agencies must use the Address Information Request Format - Government Agencies in accordance with regulations at 39 CFR 265.6(d)(5)(i) & 265.6(d)(7) when requesting address verification. The form is available online on the USPS website. You can easily request the PO Box owner’s verified address, but it must be done in writing using the correct form. While not something that the general public can easily access, obtaining the physical address of a PO Box is a little easier for process servers. Luckily, there is a fairly easy way to obtain it given that you have all necessary information. Having this information will obviously put you in a better position to effectuate service.

Unless service is being mailed using the USPS and certified mail, you will need to do some work to determine the physical address of the individual you need to serve.
