# Can you use a free Priority Mail box for Ground Advantage?

**No. USPS-produced Priority Mail packaging may be used only for Priority Mail, and USPS charges the Priority Mail price for anything mailed in it, even if the box is turned inside out or its markings are covered.**

For a 2 lb package to Zone 5 online that is $14.02 instead of $10.50 by Ground Advantage; at the counter, $17.85 instead of $14.85.

Rates verified on Oct 19, 2026

Postage in the examples is from Notice 123 effective Oct 4, 2026, which includes USPS's temporary holiday prices for Ground Advantage and Priority Mail until 12 a.m. CT Jan 17, 2027. The fees quoted here are the same as in the July 12, 2026 edition, before the holiday prices began.

## The rule, in USPS's words

> “All USPS-produced packaging (including Flat-Rate packaging) must be used only for the applicable product (e.g., Priority Mail Express, Priority Mail).”

[DMM 601.6.1](https://pe.usps.com/text/dmm300/601.htm), read Oct 19, 2026

> “The mailer of any matter mailed in USPS-produced packaging, regardless of how the packaging is reconfigured or how markings may be obliterated, must pay the appropriate product price.”

## What it costs, with examples

*Priority Mail (what a Priority Mail box costs) against Ground Advantage in your own box. Notice 123 effective Oct 4, 2026.*

| Weight, zone | Ground Advantage online | Priority Mail online | Ground Advantage, counter | Priority Mail, counter |
| --- | --- | --- | --- | --- |
| 1 lb, Zone 5 | $9.29 | $13.82 | $11.70 | $14.05 |
| 2 lb, Zone 5 | $10.50 | $14.02 | $14.85 | $17.85 |
| 5 lb, Zone 5 | $14.53 | $23.27 | $18.85 | $24.20 |
| 2 lb, Zone 8 | $13.42 | $17.22 | $19.80 | $22.55 |
| 5 lb, Zone 8 | $20.24 | $30.93 | $27.45 | $39.00 |

## Edge cases

- **Flat Rate needs a USPS Flat Rate box**; your own box never gets Flat Rate prices.
- **Hazmat:** USPS-produced packaging can't carry mailable hazardous materials or live animals, except Ground Advantage and Connect Local packaging ([DMM 601.6.1](https://pe.usps.com/text/dmm300/601.htm)); USPS also says you can't use free Priority Mail packaging for restricted hazmat ([USPS](https://www.usps.com/ship/packages.htm)).
- **The military Flat Rate box:** the APO/FPO/DPO Large Flat Rate Box ($31.34 online) pays the regular Large Flat Rate price ($32.75) if sent to a non-military address ([DMM 123.1.4.2](https://pe.usps.com/text/dmm300/123.htm)).
- **Priority Mail Express packaging** is the same: it may be used only for Priority Mail Express ([DMM 601.6.1](https://pe.usps.com/text/dmm300/601.htm)).

## What to do

- Ship Ground Advantage in a plain box or mailer of your own.
- Keep USPS Priority Mail boxes for sales where the buyer pays for Priority Mail, or where Flat Rate is cheaper than the price by weight.

## Questions

### Can I turn a Priority Mail box inside out for Ground Advantage?

No. The DMM says the Priority Mail price applies "regardless of how the packaging is reconfigured or how markings may be obliterated" ([DMM 601.6.1](https://pe.usps.com/text/dmm300/601.htm)).

### Are free USPS boxes only for Priority Mail?

USPS's free boxes and envelopes are Priority Mail and Priority Mail Express packaging, and each may be used only for its own service ([DMM 601.6.1](https://pe.usps.com/text/dmm300/601.htm); [USPS](https://www.usps.com/ship/packages.htm)).
