Secure Mailbox

Anti-fishing design, recessed doors, and serious locks to keep your mail safe.

We believe hard-working Americans shouldn’t have to worry about their mail.

Life used to be much simpler, a bit kinder. A generation ago, no one worried about mail-theft. A locking mailbox was unheard of. But times have drastically changed and now Americans lock their houses, their cars, everything. Why wouldn’t we also protect our mail, where so much private information flows?

At the end of a long day, you have a million things on your mind, but whether your mail will be in your mailbox should NOT be one of those worries. Create space to relax, unwind, and sort your mail at the end of your day. You work hard for everything in life. So protect it.

Check out all that would be very vulnerable in the hands of a thief:

Financial & Identity Items

These are some of the most dangerous if stolen because they can lead to identity theft.

  • New credit cards or replacement debit cards
  • Bank statements
  • Checks or checkbooks
  • Tax documents (W-2s, 1099s, IRS letters)
  • Insurance documents
  • Pre-approved credit card offers (can be used for fraud)
  • Social Security or government letters

Payments & Cash-Like Mail

Thieves often target these because they can quickly turn them into money.

  • Birthday cards with cash or gift cards
  • Personal checks sent for bill payments
  • Money orders
  • Refund checks
  • Rebate checks

Small Packages

Even when packages go to the porch, many small ones are left in the mailbox.

  • Prescription medications
  • Jewelry
  • Electronics accessories (earbuds, chargers, etc.)
  • Phone cases or small tech items
  • Trading cards / collectibles
  • Small Amazon or eBay orders

Medical & Personal Items

These can be valuable or sensitive.

  • Prescription drugs
  • Medical devices or test kits
  • Contact lenses
  • Health insurance cards

Resellable Items

Anything easy to flip online.

  • Gift cards
  • Event tickets
  • Collectible coins or stamps
  • Small tools

Once thieves access these items, they can steal your finances, damage your credit, and even take over your identity. We talk with customers from all over the states, who have had their identities stolen, and it is very costly, time consuming, and emotionally draining to restore.

We REPLACE other brands of locking mailboxes, every day. All locking mailboxes are constructed differently, and it MATTERS what materials, designs, and safeguards are used to prevent theft.
