Best Individual Locking Mailboxes for Rental Properties

Bellingham Mailbox

As mail theft continues becoming more common, many property managers are beginning to replace older non-locking mailboxes with more secure locking mailbox systems.

In Bellingham, WA specifically, there is an ordinance requiring rental properties to provide locking mailboxes for tenants.

The ordinance was designed to help:

  • Reduce mail theft

  • Protect renters from identity theft

  • Support tenant financial security

After installing hundreds of mailboxes for property managers, one brand continues standing out from both a security and long-term maintenance perspective: Mail Boss.

Why We Recommend Mail Boss Locking Mailboxes

One of the biggest advantages of using the Mail Boss brand for rental properties is simplified key management.

Each mailbox key is uniquely serialized. If replacement keys are needed in the future, additional keys can be ordered directly from Mail Boss using the recorded key code.

For property managers, that creates several long-term advantages:

  • No locksmith visits

  • No rekeying entire mailbox systems

  • Faster replacement turnaround

  • Lower long-term maintenance costs

When managing multiple tenants and unit turnovers, small operational details like key management can make a major difference over time.

Organizing Mailbox Keys for Rental Properties

One recommendation we always give property managers during these projects is to document mailbox information upfront.

Keeping a simple record of:

  • Mailbox number

  • Associated tenant or unit

  • Key serial number

can make future key replacement significantly easier.

Without that information, replacing mailbox keys later often becomes more complicated than it needs to be.
