British mailbox has specific regulations on the size and placement of mailboxes. The rules have two purposes: to ensure the safety of the mail carrier and motorists as well as to ensure that the carrier has no trouble getting mail delivered. It is your responsibility to make sure the box is large enough and properly installed. If the rules are not followed, no carrier cannot deliver your email and you will have to pick up the mail.
Curbside British mailbox. Contact your local post office before installing or moving a curbside mailbox. It will need to be approved. The name and address on the side of the mailbox must be at least 1 inch high. The ground should be between 41 and 45 inches from the road surface, it is not a condition that makes this impossible. If so, the post office must be notified. It must also back from the road – 6 to 8 inches from the road to the mailbox door.
The box must be on the right side of the road, based on the carrier route. If the mailbox has a lock, there must be a model approved by the postmaster, and a locked box must have a slot large enough for the carrier to incorporate the entire entry. Advertising is not permitted on the box or item. Only mail delivered by the Postal Service can be put in the box. A box for the delivery of a local newspaper can be fixed as long as it is the same distance from the curb and do not touch or disturb the operation of the British mailbox.
