Frequently Asked Questions (FAQs)

1. What size do mailbox numbers need to be?

Mailbox numbers need to be at least 1 inch tall. Numbers shorter than 1 inch may be difficult for mail couriers to read. While taller numbers can be used as long as they don't extend past the top of the mailbox, numbers shorter than 1 inch should be avoided.

2. Can you put numbers on the front of the mailbox?

Yes, it is a good idea to include a house number on the front of your mailbox, if your mailbox allows for it. This helps ensure that your address is clearly visible for easy identification.

3. What kind of glue to use on a mailbox?

For attaching numbers to a mailbox, you can use adhesive options such as Liquid Nails Landscape, Selleys Armour Flex, or White. Liquid Nails Landscape, a silicone-based adhesive, is recommended. It is important to support or protect the mailbox from being moved or bumped for the first 2-3 days after attaching the numbers.

4. Do you put mailbox numbers on both sides?

According to USPS policy, mailbox numbers must be located on both ends of the mailbox. This is to avoid confusion for delivery personnel trying to match numbers with addresses. Therefore, it is recommended to have numbers on both sides of the mailbox.

5. Do mailbox numbers have to be reflective?

While USPS recommends that mailbox numbers should be reflective and contrast with the color of the mailbox, it is not mandatory. Reflective numbers are helpful for USPS, delivery drivers, and emergency services to quickly locate your home or business, but it is not a requirement.

6. Where is the best place to put the numbers on a mailbox?

The best place to put mailbox numbers is either under the flag or to the right of the flag on the mailbox. It is important to ensure that the flag does not cover the numbers. Ideally, the numbers should be visible from both sides and the front of the mailbox.

7. Which side do numbers go on a mailbox?

Mailbox numbers, at least 1 inch tall, should be visibly positioned on the front or flag side of the mailbox. The mailbox itself should be placed 6 to 8 inches away from the curb, and the incoming mail slot or door should be 41 to 45 inches from the ground.
