What is Postage Due from USPS?

Postage due is a term used by the United States Postal Service (USPS) to refer to mail that has insufficient postage affixed to it.

When mail is sent without enough postage, the recipient is responsible for paying the remaining postage fees in order to receive the package. Postage due packages are common occurrences and can happen for various reasons.

Definition of Postage Due

Postage due refers to the additional postage that needs to be paid by the recipient of a package or letter. This occurs when the sender fails to affix the correct amount of postage to the mail item.

The USPS will then deliver the mail to the recipient, but the recipient will need to pay the remaining postage fees before they can receive the package.

Common Reasons for Postage Due Packages

There are several common reasons why a package may have postage due:

  • The sender miscalculated the weight of the package and did not affix enough postage.
  • The sender used outdated postage rates.
  • The package was sent with an incorrect or incomplete address, resulting in additional fees.
  • The sender used an improper type of envelope or packaging material, causing the package to be classified as non-machinable and requiring additional postage.

It is important for senders to double-check the weight, current postage rates, and ensure accurate addressing to avoid postage due situations.

Typical Fees and Charges

The fees and charges associated with postage due packages can vary depending on the weight, size, and destination of the package.

USPS provides a postage due chart on their website that outlines the additional fees based on these factors. It is advisable to visit the USPS website or contact their customer service for the most up-to-date information on postage due fees.

It is also worth noting that USPS offers convenient online payment options for postage due packages. This allows recipients to pay the remaining postage fees online, saving time and avoiding the need to visit a post office in person.

Tips to Avoid Postage Due Fees

Weigh Packages Before Mailing

One of the most important tips to avoid postage due fees is to weigh your packages before mailing them. This is especially crucial when sending items through USPS, as they have specific weight limits for different types of mail.

By accurately weighing your packages, you can ensure that you are paying the correct amount of postage upfront and avoid any surprises or additional charges at the receiving end. Remember, a few extra minutes spent weighing your packages can save you time, money, and hassle in the long run.

Add Extra Ounce If Close to Limit

If you’re mailing an item that is close to the weight limit for a particular postage rate, it’s always a good idea to add an extra ounce to be safe. USPS charges postage based on weight increments, so adding a little extra weight can help prevent your package from being underpaid.

This is especially important for items that are close to the next weight category, as it can result in additional fees if not properly accounted for. By adding that extra ounce, you can ensure that your package is properly classified and avoid any postage due fees.

Use USPS Price Calculator

Before sending any mail, whether it’s a letter or a package, make use of the USPS Price Calculator. This online tool allows you to calculate the postage cost based on the weight, dimensions, and destination of your mail.

By entering the necessary information, the calculator will provide you with the correct postage amount, helping you avoid any underpayment and subsequent postage due fees. The USPS Price Calculator is a valuable resource that can save you money and help ensure that your mail reaches its destination without any issues.

Buy Stamps Instead of Metering Mail

When it comes to paying for postage, consider buying stamps instead of metering your mail. Metered mail often requires a monthly subscription and can have additional fees associated with it. By using stamps, you can accurately account for the postage required and avoid any potential underpayment.

Stamps also provide you with more flexibility, as you can easily adjust the amount of postage used based on the weight and size of your mail. So, next time you need to send something, opt for stamps and reduce the risk of postage due fees.

By following these tips, you can avoid postage due fees and ensure that your mail reaches its destination without any issues.

Remember to weigh your packages, add an extra ounce if necessary, use the USPS Price Calculator, and consider buying stamps instead of metering your mail. These simple steps can save you time, money, and the hassle of dealing with postage due charges.


Getting hit with an unexpected postage due fee in the mail can be annoying.

But paying the charges quickly online through the Postage Payment Program is straightforward. Just sign up for an account, find your mailpiece, enter payment details, and submit the fees electronically.

Using a precise scale, adding an extra ounce if close to the limit, checking the USPS price calculator, and avoiding metered mail can help avoid surprise postage due charges.

Now that you know how to easily pay postage due USPS online, you can receive your packages worry-free.
