Example of Priority Mail Rate Guide

As your most cost-effective mail carrier, the USPS® offers special pricing for Priority Mail shipping including regular Priority Mail, Priority Mail Flat Rate and the new Priority Mail Regional Rate boxes. Determining which type of Priority Mail box to use can be complicated because the price varies greatly depending on the weight and destination of the package as well as type of box.

Are you getting confused? If so, you’re not alone. Many shippers are finding it difficult to compare Priority Mail rates and to find factual information that helps to simplify matters, until now.

Introducing the Priority Mail Rate Guide
To simplify everything for shippers, created a downloadable Priority Mail Rate Guide. It provides pricing for each Priority Mail box type, and within an easy-to-use table are Priority Mail boxes listed in order from lowest price to highest price. There are many benefits to using the guide, including:

  • Find the cheapest Priority Mail rate — The greatest benefit of the guide is that it can be used to identify the most cost-effective option for Priority Mail. The guide does all the work for you! Sending a 4 lb. package of clothes from Los Angeles to Florida?  By using the guide, you can identify the cheapest option and save up to $5.25, as shown in the following table:

4 lb. Package of Clothing – From California to Florida

Priority Mail Type: Cost:
Priority Mail Regional Rate – Box A $9.37
Priority Mail Flat Rate – Medium Box $10.50
Priority Mail Flat Rate – Large Box $14.20
Priority Mail Regional Rate – Box B $14.62
Priority Mail (regular) $14.62
  • Avoid the myths about Priority Mail — The guide helps to identify facts about Priority Mail. For example, many shippers think Priority Mail Flat Rate is always the cheapest option based on TV commercials featuring the tagline “If it fits, it ships.” Using the chart will show that regular Priority Mail or Regional Rates are often much cheaper options.

PRIORITY MAIL TIP: For a 1 lb. package, regular Priority Mail beats out all other options except the Priority Mail Small Flat Rate box, which is very limited in size.

  • Find low-cost Priority Mail Regional Rates for nationwide shipping — Many shippers also think that Regional Rate boxes are only for local shipments in the same region because “Regional” appears in the name. Using the guide will show that Regional Rate boxes are cost-effective for nationwide shipments too.

PRIORITY MAIL TIP: Excluding the Small Flat Rate Box, Regional Rate Box A is the lowest cost option for ALL zones for packages weighing between 2 lbs. and 15 lbs.

  • Find the best Priority Mail Flat Rate for heavy packages — If you are shipping heavy packages, there is no cheaper option than Priority Mail Flat Rate boxes. Using the guide demonstrates this as well.

PRIORITY MAIL TIP: Shipping packages that weigh 20 lbs. or more? Use Priority Mail Flat Rate. You pay the same low flat rate cost whether it weighs 1 lb. or 70 lbs. and cost efficiencies start at 20 lbs.
