Bellingham’s trusted solution for mailbox upgrades and replacements.
Bellingham Mailbox is a local business specializing in high-security locking mailbox installations, post replacements, and custom mounting solutions. We combine quality craftsmanship with durable materials, every install is carefully measured, leveled, and reinforced to ensure long-term stability and protection. Serving homeowners, property managers, and builders across Whatcom County, we help improve both mail security and curb appeal with professional, USPS-approved solutions built to last.
Ever wonder how a USPS Cluster Box Unit (CBU) parcel locker works?
When a CBU is at capacity or a package is too large to fit inside a resident’s mailbox, the mail carrier places it in a secure parcel locker and leaves a key in the resident’s mailbox. The key provides one-time access to retrieve the package safely and securely.
Parcel lockers help reduce package theft while providing a convenient delivery solution for apartment complexes, HOAs, townhomes, and community mailbox installations.
Upgraded this rental property to secure locking mailboxes in compliance with BMC 6.15.050, a local code requiring locking mailboxes for rental properties.
We completed the installation without disrupting current mail delivery for tenants. Clean, secure, and built to last 📫
