What is the difference between a mailbox and post combo and a standalone mailbox?

A combo includes both the mailbox and a matched post, with the mounting pattern, diameter, and arm length pre-fitted. A standalone mailbox is sold on its own and must be paired with a compatible post you source separately.

How tall does a mailbox need to be installed?

USPS requires 41 to 45 inches from the road surface to the bottom of the mailbox, with a 6 to 8 inch setback from the curb. Every USPS-approved combo on this page meets these figures when installed per the included instructions; a handful of specialty designs elsewhere in our catalog aren't USPS-approved, so check the individual product page to confirm before you buy.

Can I install a mailbox and post combo myself?

Yes. Most homeowners finish in two to three hours with basic tools, whether the post goes in-ground with a set footing or mounts to a pad with surface-mount hardware and no digging. Instructions ship with every combo, and replacement parts cover anything missing on arrival.

What size mailbox do I need for my household?

Most of our combos are tagged for small packages, letters, magazines, and catalogs. If you regularly receive parcels, filter for large packages, or choose a dedicated parcel box so nothing gets left on the porch.

Do you sell locking mailboxes?

Yes, 275 of our 407 combos include locking mechanisms, from keyed cam locks to combination locks that need no key at all. Locking options are available across most style and material categories, and a handful of collections offer more than one mechanism to choose from.

Do you carry mailbox and post sets for multiple units?

Yes, we stock 16 combos in dual, triple, and quad configurations for shared driveways, duplexes, and HOA developments, each unit matched in hardware and finish. Contact us for a bulk quote if you're specifying for more than a handful of units.
