Location

• Consider the most convenient location for you to retrieve your mail. It might be close to your home or office. Also, remember that in addition to the United States Postal Service, many other organizations offer private P.O. boxes. Look in your yellow pages for a listing near you.
  
  

Identification

• The amount of identification varies, United Parcel Service, for example, requires two forms of identification one of which must include a photo. Some other establishments require three forms of identification. Some acceptable forms of identification include a driver’s license, passport, Green Card, military or Native American ID.
  
  

Mailbox Service Agreement

• Be prepared to complete an application or mailbox service agreement between you and the P.O. Box holder. This may require a deposit for your key and an up-front payment for a minimum amount of time. Be sure and ask any questions before you sign the agreement.
  
  

Rental duration

• Determine how long you’ll need to rent the box. Generally, the fees are cheaper the longer you rent the box. If you’re not sure or are planning on moving, be sure and ask if your mail will be forwarded and if there’s a similar establishment where you’re relocating.
  
  

Box size

• Prices increase substantially the greater the box size. Depending on whether you’re using the box for private or business use, you may want to secure a larger than standard box size. If you anticipate a great deal of oversized packages or other items to be delivered regularly, you should inquire about the costs for a larger box size.
