Mailbox Regulations For The Construction 

A mailbox should have the Postmaster General’s seal (PMG). If you make your mailbox or buy a custom-made mailbox, it should meet the PMG standards. For approvals, you can contact your local postmaster. 

  • The USPS mailbox regulations apply to the post box mailboxes, mailbox kits, parcel mailboxes, and wall mount mailboxes. 
  • The USPS has specific mailbox sizes which you should not exceed.
  • The address numbers on the mailboxes must be 1 inch bigger and clear to the delivery men.  
  • In case your mailbox is not on the same street where you stay, put your complete address on it. 

Mailbox Regulations For The Placement

It will help if you place your mailbox at an ideal distance so that the mailman easily delivers the mail. Here is the placement of your mailbox. 

  • Position your mailbox accurately at a distance of 4″ 1 to 45″ from the road to the bottom of the mailbox. This will allow the mailman to deliver your mail from his van easily. 
  • You should position your mailbox at a 6″ to 8″ back from the curb. If you do not have an elevated curb. Reach out to the local postman immediately. 
  • Put your house number or apartment number clearly on the mailbox. 
  • If your mailbox is on a different street from your house or apartment, write your complete address on the mailbox. Remember that it should be big and clear enough to read. 
  • Your mailbox should face outward and be placed on the right-hand side of the door.
  • You can put neon stickers or glowy paint on the mailbox to be visible at night. 

Mailbox Regulations For The Installation  

An ideal mailbox has stable support and bends or falls away if a vehicle hits it. The Federal Highway of Administration suggests the following things to install a mailbox correctly. 

  • Support of the 4″ ×4″ or a 2″ diameter standard steel or aluminum pipe is necessary. 
  • Avoid unyielding and dangerous supports, for example, heavy metal pipes, concrete pads, and farm equipment or cans filled with concrete. 
  • Do not buy a post more than 24″ deep. 

Mailbox Regulations For The Door 

Some houses and buildings have slots in the door for receiving the mail instead of having a mailbox. Let’s read if that’s appropriate or, if not, what’s the ideal way to do so. 

  • The door slot should be approved when the opening is at least 1 ½” × 7″. 
  • The bottom of the door slot should be at least 30″ above the floor. 
  • The horizontal compartments should have a flap hinged at the top surface. 
  • Vertical slots should be attached on the other side of the door hinges. 

For better privacy, you should install a mail slot on the side of the door. The standards for door slots are as follows: 

  •  The hood should not allow the view of 2 1/16″ of the door. 
  • The horizontal slot should not extend below the bottom of the outside plate. 
  • On the vertical slot, the hood should not extend beyond the side of the outside plate on the same side of the door hinges. 

Wall-Mounted Mailbox Regulations 

Here are some of the most important points for wall-mounted mailbox regulations:

  • If you wish to replace your curbside mailbox with a wall-mounted mailbox, you should get your local postmaster’s permission. 
  • Choose from various styles and sizes as the mounted mailboxes need not have the PMG or Postmaster General’s seal for approval. 
  • Get a wall-mounted mailbox that can carry a good volume of mail and envelopes. It should be big enough to carry letter-sized envelopes, catalogs, and postcards.
  • Place the mailbox near the main entrance, easily visible to your mailman. 

Packaged Mailbox Regulations

A packaged or locked mailbox keeps letters and parcels secure. Postal workers cannot keep keys, so choose a locking mechanism mailbox that allows your carrier to deliver your mails. 

Private Mailbox Regulations 

According to the private mailbox regulations and concerned authorities, individuals and businesses can purchase a private mailbox without associating it directly with themselves. According to the mailbox guidelines, the only people who have access to the mailbox are the mailman and registered users. 

However, if you wish to rent a personal mailbox, you must provide at least two forms of identification, including a photo of yours.
