FAQ: Real Customer Questions, Problems & Clear Answers

1. Why do FedEx, UPS, and Amazon say my PO box is “undeliverable”?

Because PO boxes can only receive USPS mail.

 This is the #1 complaint from frustrated customers, especially online shoppers.

Common user comments include:

  • “UPS keeps returning my packages.”
  • “Amazon won’t ship half my orders to my PO box.”

If you frequently order from Amazon, Shein, Walmart, eBay, or any retailer using third-party couriers, this becomes a dealbreaker.

2. Why is my USPS Informed Delivery showing mail that never arrives in my PO box?

Many users report:

  • Items scanned but not placed in their box
  • Missing letters
  • Delays of several days
  • Packages stuck “available for pickup” but not actually retrievable

These issues often occur due to:

  • Staffing shortages
  • Sorting mistakes
  • Overflow during peak seasons
  • Misplacement behind the counter

Tip: Always keep tracking screenshots if something goes missing.

3. My PO box is cheap, but why does it overflow so fast?

Small PO boxes fill up within a day or two if you receive:

  • Amazon bubble mailers
  • Slightly thick envelopes
  • Shoe-box sized items
  • Multiple packages in a week

When this happens, USPS may:

  • Move packages to the back
  • Leave pickup slips
  • Return items if space runs out

Many customers complain that their “cheap small PO box” becomes unusable for real package volume.

4. Why do I still have to stand in long lines if I have a PO box?

Because boxes can only hold mail, not most packages.

You’ll often need to stand in line when:

  • Packages are too large
  • Multiple items arrive at the same time
  • The box is full
  • Items require ID pickup

Users report waiting 15-40 minutes, sometimes longer during lunch hours or holidays.

5. Are PO Boxes Really Secure? What Customers Report

Most PO boxes are safe, but users occasionally report issues such as:

  • Mail placed in the wrong box
  • Boxes that don’t lock securely
  • Unattended packages left behind counters
  • Lobby areas without cameras or overnight monitoring

These concerns often surprise customers who assume PO boxes guarantee perfect security.

6. Are PO boxes really 24/7?

Not always.

Many customers only find out after renting that:

  • Lobby access ends at 5 p.m. or 6 p.m.
  • Weekends have limited or no access
  • Smaller post offices close earlier
  • Holiday schedules vary

People who work full-time often struggle to access their boxes without rushing.

7. Why is my PO box price higher than what USPS showed online?

Real customer frustrations:

  • Online prices don’t reflect local availability
  • Cheap sizes may be sold out
  • Busy ZIP codes cost significantly more
  • Forced 6-month or 12-month prepayment feels expensive upfront
  • City PO boxes can run $70- $120+ per month

Customers frequently mention that the “cheap PO box” they expected ends up being much more expensive.

Hidden USPS Fees & Unexpected Costs to Be Aware of :

While PO boxes look affordable upfront, customers frequently report unexpected charges such as:

  • Fees for after-hours or restricted pickup
  • Replacement key fees ($6-$20 depending on location)
  • Higher costs for premium forwarding services
  • Local price variations not shown in USPS online listings

These hidden costs often make PO boxes more expensive than originally expected.

8. Can I use a PO box as a business address?

There are limitations:

  • Many platforms don’t accept PO boxes (Google Business Profile, couriers, banks, etc.)
  • You can’t receive non-USPS business shipments
  • Some licenses require a physical address

Users often report frustration when they realize a PO box doesn’t qualify as a real business mailing address.

9. Why do people switch from PO boxes to package receiving services like Stowfly?

Based on user feedback, the top reasons include:

✔ Accepts ALL carriers

No more “UPS undeliverable” or “Amazon won’t ship to PO box.”

✔ Flexible pickup hours

Location partners include convenience stores, salons, cafés, etc., often open early mornings, late evenings, and weekends.

✔ Affordable & predictable pricing

Subscriptions typically cost the same, or less than many PO boxes.

✔ No overflow risk

Packages up to 2 ft x 2 ft x 2 ft and 50 lbs can be held securely.

✔ Works for online shoppers

People ordering from Amazon, Walmart, Temu, eBay, and Shein find it far more convenient.

10. Is a PO box good for preventing package theft?

Only halfway.

 It prevents USPS packages from being left at your door, but it does not protect:

  • Amazon deliveries
  • UPS shipments
  • FedEx packages
  • DHL parcels
  • Most online store orders

Users searching for “cheap PO box to prevent package theft” often discover it doesn’t solve the full problem.

11. What’s the best alternative for receiving packages securely?

For most shoppers, travelers, renters, and small businesses:

A package receiving service like Stowfly is more flexible than a PO box or mailbox for rent because:

And many customers appreciate the peace of mind knowing every package is actually delivered, not returned, lost, or delayed. So no more dealing with missed deliveries and lost packages.

Final Thoughts: What Users Should Know Before Renting a Cheap PO Box

PO boxes can be a great solution, if:

  • You only need USPS mail and package deliveries
  • You rarely receive packages
  • You want the lowest possible cost in small towns

But for online shoppers, apartment residents, remote workers, and frequent travelers, the limitations are significant.

This is why so many customers end up switching to Stowfly, which delivers flexibility and reliability without the traditional PO box frustrations.
