Mailbox Keys

  • Update your mailing address before moving. You can change your address by visiting the USPS Change of Address page. You’ll also need to transfer all your subscription services, update your ID or driver’s license, update your car registration and insurance, etc. 
  • Talk to your builder about obtaining your mailbox keys. If your builder doesn’t have the mailbox keys, please pick them up at the Littleton Post Office at 8200 Shaffer Parkway in Littleton.
