Mailboxes R Us Inc Alaskan Owned & Operated

Mailboxes-R-US (MBRUS) owns and maintains the CBU, leasing out the mailboxes to residents within an area defined by the local Postmaster.

An annual contract will be issued by MBRUS to the lessee.  You cannot sublet or resell the mailbox assigned to your address.

MBRUS issues two keys with each mailbox when the contract is signed and payment is received.  Extra keys can be made by a local locksmith. If MBRUS provides replacement keys, it will cost $50. Replacement locks are available for $70.  The Post Office does not have any keys for the individual mailboxes, only a master key to access the front of the CBU for mail delivery.

The Post Office requires you use the house number & street address issued to you by the Matanuska-Susitna Borough to receive mail in a CBU.  If you are unsure of your house number and street address, it is available from the Mat-Su Borough and is also printed on your property tax assessment card or bill. We can help you find the address they have on file. If there is an error with your address (driveway on different street then stated, etc.), please contact the Borough; the Post Office cannot make changes to an address issued by the Borough.

MBRUS will notify the mail carrier of your new mailbox – the box number assigned to you, your name and physical address .The box number assigned to you does NOT become part of your mailing address. A label with your address will be put inside your box to help the USPS Mail Carrier identify it for delivery purposes.

If you do not have an existing roadside mailbox and you live in the Wasilla area, you will need to apply, in person, at the Wasilla Carrier Annex for mail delivery service using PS Form 5431. They require that you bring a photo id and proof of your street address (Borough tax assessment, utility bill, closing document or rental agreement).  The Postmaster will verify your street address and your mail delivery location (the street/intersection on mail carrier route that is closest to your home). This needs to be done before you can receive mail in the box assigned to you. Palmer area residents do not need to go thru this process at their Post Office but we will verify your street address with the Borough database before assigning a box to you and notifying the mail carrier of your delivery information.

Once your mail carrier has been notified of your box assignment it can take 2-4 weeks to have delivery service setup in their system. When this delivery setup is complete, you can file a Change of Address form available online at usps.com or at the Post Office. After this form is filed and confirmed by the USPS (1-2 week process), they will forward your first-class mail to your street address for one year. This gives you time to notify your utility, insurance and credit card companies, employers, doctors, bank, the IRS, MSB and DMV, magazines, family, friends and anyone else you might receive mail from. 

It is highly recommended that you keep your alternate mailbox during this 3-4 week transition period for new delivery service & mail forwarding setup. You will be less likely to miss any mail or have it returned to sender by the Postal Service.

While it is not necessary to notify us if you move, it is appreciated if you do. Whether or not you pass the keys along to the new homeowners, please let them know they are to contact us to continue to use the mailbox.  If we don't hear from the new residents, the lock on the mailbox will be changed in preparation for someone else to use.

There are 2 parcel compartments in each CBU for receiving small packages or large bundles of mail.  There may be more than one cluster box at your location.  When you receive a package, the mail carrier will put a key to one of these parcel boxes into your mailbox. The id on the key will tell you which box contains your parcel. Once you access the compartment to retrieve the package, the key will remain in the door.  Only the Mail Carrier has the key to remove the parcel key from the door. If your package does not fit into one of the 2 compartments, or the compartments are full, you may receive a notice to go to the window, or a key with an id tag directing you to the parcel lockers, at the mail facility for your zip code.

Each CBU has an outgoing mail slot that is only accessible by the USPS Mail Carrier.  Make sure the mail piece is pushed all the way into the slot and not resting on the shelf in the opening. We encourage everyone to use this as a safer, more secure way of sending mail.

The contract is a pdf file that can be viewed and printed. It also includes the information above on procedures for setting up mail delivery service to a roadside box. The Application is available as pdf and as Word .doc format.  The form can be filled out and mailed or scanned and emailed to us. Contact us if you prefer to have these documents mailed or emailed to you. We do not have a fax machine. We will review your information and mailbox availability in your area, then contact you to setup a time to meet you at the CBU.
