Replacement Parts & Key Blanks

Are key blanks available in-store?

No, they are not available in-stores, but key blanks are available to order as a 4-pack via homedepot.com or amazon.com or you may call your local locksmith to determine if they have your specific  Architectural Mailboxes key blank in stock. To find the proper key for your mailbox, please reference the infographic below. Once you receive your key blanks they must be taken with your original key to your local locksmith to be cut (automated machines cannot cut specialty dual sided key blanks).

Can I get my mailboxes keyed alike?

Yes. For certain applications, it makes sense to have all locks use the same key profile. Examples include locking mailboxes used as paperwork drop points on a medical campus, or several key drop points at a car dealership. You can order a set of locks that are all keyed alike. For further instruction on this topic, please contact your Architectural Mailboxes dealer for more information.

How many keys come with my mailbox?

All mailboxes manufactured by Architectural Mailboxes come with 2 keys. The only exception to this rule is the Oasis 360 (item number: 6300) and it comes with 4 keys. If additional keys are needed, please see the FAQ question, “Are key blanks available in-store?”.


How do I mount multiple mailboxes to one post?

Our Duo, Tri and Quad Spreader Plates are designed to mount two, three or four mailboxes to one post, respectively. If you have a mailbox with a recessed (false) bottom, you will also need the Mailbox Spacer Kit for each mailbox in order to successfully mount your mailboxes.

Are there mailbox guidelines I need to know before installing my mailbox?

We recommend checking with your local post office, but general USPS mailbox installation guidelines include positioning your mailbox 41″ to 45″ from the road surface to the bottom of the mailbox or point of mail entry and 6″ to 8″ back from the curb. If you do not have a raised curb, contact your local postmaster for guidance.

Why is mounting hardware not included with my mailbox?

There are many different possible installation methods and configurations for mailboxes, including onto existing wooden posts, along mounting rails with other mailboxes, inside of masonry columns, or onto optional manufactured posts. Because of the great variety of possible mounting options, it is not feasible for mailbox manufacturers to include hardware for every possible variation. However, the appropriate hardware is included with all the different post and accessory products we make. If you buy one of our posts, it will include the correct hardware to properly and securely mount one of our mailboxes.

How do I install my product?

We provide full assembly instructions for each of our products. You can find these instructions on each product page of our website.  Please refer to the product(s) you have purchased to download the instructions.

Can I install your house numbers on my mailbox?

Although it is possible to attach Architectural Mailboxes’ house numbers, we don’t recommend it. The use of adhesives or penetrating your mailbox body may damage the product and will void your warranty.

Can I mount my new mailbox to my existing post?

We’ve been at this for a long time and we’ve seen almost every kind of installation under the sun. The majority of installations use a 4×4 wooden post, and we have a great solution for it: the 3-way 4×4 adapter plate. If you have a post made by one of our competitors, our mailbox will fit it if it uses the informal industry standard 4″ x 10″ bolt pattern. Here is an illustration of our bolt pattern, and every one of our post mount mailboxes uses this pattern. If your existing post uses a different pattern, we recommend attaching your own “DIY” wooden adapter to your existing post, then attaching your mailbox using the 4″x10″ pattern. Do not drill new holes into your mailbox or it will promote corrosion and void your warranty.

Mailbox Care & Warranty

Can your mailboxes be painted?

Yes, they can be painted, but this will void your warranty. The powder coated surface of most of our products serves well as a painting substrate. To ensure the best adhesion possible, make sure the product is clean and dry, use a primer, and use a paint designed for outdoor use.

Is there a warranty on my product?

Architectural Mailboxes guarantees their products against structural defects, under normal use and proper assembly, for the lifetime of the product. Our complete Structural User Warranty can be found here.

If your product was purchased before January 1, 2017, you are covered under our 5 year warranty found here.

How can I protect my product against harsh weather?

All of our mailboxes are made with materials designed to withstand outdoor exposure. We use galvanized steel, aluminum, stainless steel, and ocasionally UV-resistant plastic. These materials serve well when exposed to the elements. Additionally, all metal parts are pre-treated then powder coated with a material specially formulated for outdoor use. Powder coating is a painting process that creates a chemically cross-linked finish that is very durable and long-lasting, similar to the process used for cars. Despite the steps we take to design our products for outdoor use, improper installation and care can lessen the life span of our products. Please use the following guidelines to give your mailbox a long and happy life:

  • Never install mailboxes or posts in the path of sprinklers. Regular exposure to water can promote corrosion and build up calcium deposits on the surface.
  • Wall mount mailboxes are designed to mount on walls, under roof eaves. While we design all our mailboxes for proper water flow and drainage, direct and driving rain can find it’s way into wall mount mailboxes if installed in open areas.
  • Keep your mailbox clean. We suggest wiping it down every season, with a clean cloth and a mild detergent. This removes dirt and dust buildup, which can contain corrosive chemicals that can damage the finish.
  • The powder coated finish can also be cleaned with protective cleaners, such as car wax. We don’t maintain a list of approved cleaners, so please test a small hidden area of your product before using such cleaners to make sure it doesn’t damage the surface.
  • If you want to install your mailbox into a wall or other structure, such as a masonry column, please consult a qualified carpenter or mason. Discuss the potential for water intrusion with your chosen professional and make sure she or he installs the mailbox to prevent water pooling and promote proper water drainage.

What do I need to provide for a warranty issue?

We guarantee our products against structural defects, under normal use and proper assembly. If you are experiencing an issue with one of our products, please contact our Customer Experience Department for more assistance. You will need proof of purchase (original sales receipt) and all details about the issue you are experiencing.

How do I fix chipped paint on my product?

If you have a small blemish on your product, contact us to order touch-up paint. We have touch-up paint for almost every powder coat color we offer. To ensure the best adhesion possible, make sure the product is clean and dry, and clean off any residual powder coat chipping. If you want to paint the entire product, we recommend using a primer and a paint designed for outdoor use.

How should I care for my mailbox?

Like any consumer product available today, mailboxes also need love and care. We take great pride in producing products that can withstand weather and elements with rigor, however, regular cleaning of your mailbox is a necessary part of mailbox care. We like to use the analogy of a car; if your car is dirty from the elements, your mailbox probably is too and will need a good cleaning. Please follow our Care and Maintenance Instructions for proper procedure. Happy cleaning!

Are your mailboxes USPS approved?

Yes, all of our mailboxes that are subject to USPS approval are formally and officially approved. We go through every step of the arduous process to properly design, test and certify our products according to the stringent USPS Standard 7 requirements. It is important to note that there are many mailbox manufacturers who simply stamp their mailboxes “US MAIL – Approved by the US Postmaster General,” but whose mailboxes are not actually approved. While this is both illegal and unethical, the USPS enforcement system is insufficient to ensure this activity does not take place. When in doubt, contact your local USPS Postmaster and ask them to provide you with the latest list of approved receptacles. You can also find the official list, published once a year, through USPS’ postal bulletin, found here: USPS Postal Bulletin
