Pricing and Costs
The cost of Priority Mail postage can vary widely, but it's generally cheaper than many other shipping methods. The USPS offers a range of pricing options, including Flat Rate and Priority Mail.
Flat Rate Priority Mail prices start at $8.05 for an envelope and $8.55 for a small box. The maximum weight restriction for domestic mail is 70lbs. You can only get the flat rate prices if you pack your mail with USPS-produced Flat Rate Envelopes or Boxes.
Priority Mail rates are typically as follows: starting at $9.00 for letters, parcels, and large envelopes shipped at a Post Office, and starting at $7.62 for letters, parcels, and large envelopes shipped via Commercial Base or Commercial Plus.
The cost of shipping a package also depends on its weight and the distance of the mail route. For example, a 1-pound package shipped to Zone 1 & 2 would cost $7.35, while a 2-pound package would cost $7.85.
To give you a better idea of the costs involved, here are the retail postage rates for Priority Mail:
It's worth noting that the Small Flat Rate Box, priced at $7.90, can be a cost-effective option for packages weighing up to 70lbs.
Zone and Weight-Based Pricing
Zone and weight-based pricing can be a bit tricky, but understanding how it works can save you money and hassle. USPS has a zone chart to calculate the distance between origin and destination zip codes, with 9 zones covering the continental US, Alaska, Hawaii, and US Territories.
USPS zones are dynamic, meaning they'll be different based on your location. For example, Zone 1 for a Miami zip code won't be the same as Zone 1 for a Los Angeles zip code.
If you're shipping a small package, weight-based pricing can also come into play. For example, if your package weighs less than 1 lb, 0 oz, it'll be shipped to Zone 5-9, regardless of the destination. Here's a breakdown of weight-based pricing for small packages:
Remember, the larger the package, the more zones it can be shipped to. For example, a 21-pound shipment within Zone 1 will be more economical to ship in a Large Flat Rate Box, which costs $19.95.
Understanding Zones
USPS zones are dynamic, meaning they will be different based on your location. For example, Zone 1 for a Miami zip code would not be the same as Zone 1 for a Los Angeles zip code.

There are a total of 9 USPS zones, with Zones 1-8 covering the continental US, Alaska, Hawaii, and US Territories, and Zone 9 covering US Territories, Commonwealths, and the Freely Associated States in the Pacific Ocean.
The larger the zone number, the further the destination zip code is from the origin zip code. Zone 1 contains zip codes that are nearest to the origin zip code, while Zone 9 zip codes are the furthest distance from the origin zip code.
Here's a general idea of what the USPS Zone Map would look like for a zip code in Los Angeles: the area near Los Angeles would be purple, or Zone 1, while the eastern United States, most of Alaska, and Hawaii would be orange, or Zone 8.
You can enter origin and destination zip codes on USPS' Domestic Zone Chart to find out what zone you're shipping to.
Here are some weight and zone exceptions for the USPS Medium Flat Rate Box:
Similarly, here are some weight and zone exceptions for the USPS Large Flat Rate Box:
Medium

The Medium Flat Rate Box is a great option for shipping packages, but it's not always the cheapest choice. The USPS Medium Flat Rate Box costs $14.35, and it measures 14” x 12” x 3 ½” in size.
If your shipment weighs under 2 pounds, USPS Priority Mail rates will be cheaper than the Medium Flat Rate Box. This is a key consideration when deciding which shipping option to use.
In some cases, the Medium Flat Rate Box is still the best choice, even if it's not the cheapest. For example, if you're shipping something between 1 lb, 1 oz - 2 lbs to Zone 9, it's best to use the Medium Flat Rate Box.
Exceptions: Under 2 Lbs
If you're shipping a small package weighing under 2 pounds, there are some specific rules to keep in mind.
For packages weighing less than 1 pound, you can ship them to zones 5 through 9.

Packages weighing between 1 pound 1 ounce and 2 pounds can be shipped to zones 3 through 9.
Here's a quick rundown of the weight and destination limits for packages under 2 pounds:
