4C Mailbox Use and Regulations:
As of 2006, all new construction, new mailbox applications and major renovation sites using centralized wall-mounted USPS mail delivery are required to have a 4C mailbox system. To adhere to USPS installation requirements, your 4C Mailbox:
- Should not exceed 67” from the finished floor to the top row of locks
- There must be at least 28” from the finished floor to the bottom of the lowest tenant compartment.
An exception can be made and this dimension can be minimized as low as 15” only when the lower compartments are 4C Mailbox parcel lockers. Our 4C horizontal mailboxes are front-loading only (mail carrier access from the front).

Parcel Locker Requirements
You must satisfy a 1:5 parcel locker to mailbox ratio requirement. If the number of parcel lockers in your mailbox installation exceeds the 1:5 requirement, smaller parcel lockers may be included.
For example - if your project requires 100 mailboxes, at least 20 parcel lockers with a minimum size of 15"H x 12"W x 15"D must be included.
BE SURE TO NOTE the parcel locker height when utilizing only one 4C module type. Not all built-in lockers are 15" tall and may require the addition of parcel only modules to comply with the 1:5 parcel locker USPS requirement.
