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 Delivery Amigo?
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

✔ 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 Delivery Amigo is more flexible than a PO box or mailbox for rent because:
Accepts packages from every carrier, thereby avoiding instances of not only USPS missing packages, but also Amazon missing packages, UPS lost packages, and FedEx stolen packages.
Offers convenient & flexible pick up hours

Works for personal or business use

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
