Secure, Well-Built Mailbox with Easy Installation
This lockable post-mount mailbox is great quality and feels solid and secure. Installation was straightforward with no issues, and everything fit as expected. The anti-theft locking feature works well, and the mailbox has plenty of space for daily mail. A small but appreciated detail is that the flag stays up properly without falling over. Overall, a reliable and well-designed mailbox that does exactly what it’s supposed to do.

Edit: Great Customer Service!
Looks great but gets rusty and the door doesnt close. We just installed this in August of 2025 and these pictures are from April of 2026. Looks good until it doesn’t May 2026 Edit: I reached out to them, and within an hour they sent me a replacement! Great customer service

Beautiful and solid.
I love the color, the size, and the texture of this mailbox. The only reason it's not getting 5 stars is maybe silly... It's because I can't just leave the key in the door when I open it to get my mail. If I do, and swing the door down, the key falls out and I have to get out of my car and look for it on the ground. So, reality is, I wish the key stayed secure in the lock until I swing the door back up and lock it. Otherwise, very good quality.

NOT a USPS approved mailbox!
There is no doubt the quality and style are the best of the best! We love this mailbox! Big crushing downfall though; it is NOT APPROVED by the USPS and mail will NOT be delivered to it, per the USPS. EVEN THOUGH IT IS LISTED when Approved USPS is queried on Amazon, it is NOT. When I reached out to Adoorn, because their website proudly states it meets all USPS requirements, here was the response I got. "We’re happy to share that the Adoorn Non-Locking Mailbox meets all USPS requirements. We’ve been working closely with the USPS Engineering Systems – Delivery Technology Department for the past year and have received preliminary approval based on our design and build quality. While most mailboxes on the market don’t go through this level of review, we’ve chosen to pursue official certification for models that qualify. Once the final paperwork is complete, the front panel will be updated to include “US Mail. Approved by the Postmaster General.” In the meantime, we’ve been cleared by USPS leadership to continue selling these units, and we’ve delivered hundreds of thousands of Adoorn mailboxes with no issues. Let us know if you have any other questions—we’re proud to stand behind the standards we build to." For the record, we purchased the locking mailbox. So why are those on the website, again stating it meets USPS requirements, when it is NOT even in the process of approval. Again, the website states it meets requirements. I call this FALSE ADVERTISING.

High quality mailbox - but not USPS compliant
Major note for anyone considering this item. It is beautiful, it is solid, it is high quality - but it is NOT compliant with USPS regulation post office boxes. I have gone through such an ordeal and my postmaster is forcing me to remove the box. Adoorn customer service has been wonderful and they are shipping me a new one, but it has caused such a headache.
