Can you find the name of the manufacturer somewhere on the existing mailbox?

Sorry Joe but you won't find one. All USPS mail boxes must be approved by the post master of the united states, and if you look at any in the store you will see this stamped into into the metal frame.

If you make some nasty pile of a box that isn't approved the carrier can refuse to deliver to the boxes, and hope your carrier knows the regulations and does refuse. Would you want to shove 8" long mail into 4" long boxes all day?

This is close, looking for "apartment mailboxes".

That site’s smallest mailbox is 6 3/8” deep. You might have to check with other building owners where they got theirs, otherwise you (or the handyman) probably have to build out the structure to accommodate the new standard.

I need to see where that original one was on the house.Do you never get pkgs ? I do not understand the issue with going a proper depth or better yet a post with a milbox insted of attched to the house .

What is behind the current mailbox that prevents you from using a deeper mailbox?

This style mailbox is common and approved by the USPS.

@outpaientzero -- I think they mean "deep" like back into wall, not like the length of the boxes top to bottom....

Are you a landlord? Go to your LOCAL post office asap.

You are going to have trouble soon......: ) from any older tenant/owner.

Or.... cut back the NEW box to a 4" depth.

Folks?

Ask a postman. So LITTLE mail is actually what you would refer to as mail. Trust me, it fits in there, and they simply bend or fold. Catalogs and coupons? A bin in the foyer and nobody takes the copious "refuse". I toss it every week to recycle! Trust me. I live multi dwell.

There is absolutely nothing wrong with it sticking out of the hole by a couple inches. Most I've seen are surface mounted anyway.

Good point. They're all ugly anyway : ) Close the whole, get a bigger one to cover the entire mess
