Frequently Asked Questions (FAQs)

1. Do mailbox posts need concrete?

While it is not necessary to set a mailbox post in concrete, it is highly recommended. Concrete provides a strong foundation for the post, ensuring stability and durability for your mailbox. It is generally advised to dig a hole 1/3 to 1/2 the height of the post and set it in concrete for optimal support.

2. Can I use a steel post for my mailbox?

Using a steel post for your mailbox is acceptable as long as it meets Federal Highway Administration guidelines. The recommended options include a 4 x 4-inch wooden support or a 2-inch diameter standard steel or aluminum pipe. It is important to avoid unyielding supports like metal or concrete posts to ensure safety in case of a collision.

3. How far down should a mailbox post be in the ground?

When installing a mailbox post, it is suggested to dig a hole deep enough so that the height of the mailbox is approximately 42 inches above the ground surface. The depth of the hole should not exceed 24 inches. It is always recommended to contact 811 before digging to avoid any potential damage to underground utilities.

4. Is filling mailbox post with concrete illegal?

The use of concrete for mailbox posts may be prohibited in some local municipalities due to safety concerns. Concrete posts can pose a hazard to motorists and passengers in case of a collision. The impact with a concrete post can result in serious injuries. It is important to check with your local regulations to determine if filling mailbox posts with concrete is allowed.

5. How deep should mailbox post be buried?

The Federal Highway Administration recommends using a 4 x 4-inch wooden support or a 2-inch diameter standard steel or aluminum pipe for a mailbox post. It is advised to avoid heavy metal pipes, concrete posts, or other potentially dangerous supports. The post should be buried no more than 24 inches deep to ensure stability and safety.
