Last updated September 10, 2024

At least once a year – and sometimes multiple times a year –  the United States Postal Service (USPS®) changes postage rates. At Stamps.com, we value transparency and strive to keep you updated on rate changes that can have an impact on your mailing and shipping expenses. 

This blog will help you understand these adjustments and ensure you’re always up-to-date with the latest USPS rate changes.

The good news, no matter what, Stamps.com will strive to get you best-in-class discounted rates for every mail class and shipping service available through USPS – and of course, more of your favorite carriers.

What is a rate change?

In case you didn’t know, USPS periodically adjusts its shipping and mailing rates. These changes can affect the cost of sending packages and letters depending on the service you choose, weight, destination, and other factors. We often refer to these adjustments as rate changes or rate adjustments. 

October 2024 rate change

USPS is temporarily raising rates for select package services from October 6th to January 19th. This is a common practice among major carriers like FedEx and UPS during the holiday season to accommodate the surge in shipping volume and maintain service quality.

For more information on impacted service check out our 2024 Holiday Surcharges blog.

September 2024 rate change

On September 16, 2024, the USPS adjusted rates for Priority Mail® and Ground Advantage™ packages shipped to certain ZIP Codes. This meant the cost to ship these packages might have increased slightly depending on the destination.

Despite these USPS changes, your rates will continue to be better than what you would pay at the Post Office. Impacted ZIP Codes will enjoy up to 41.66% off USPS Priority Mail® and 48.92% off USPS Ground Advantage™ when you ship through Stamps.com. Additionally, you’ll continue enjoying best-in-class discounts on USPS rates whenever you print stamps or shipping labels with Stamps.com. See the table below.

New mailing technology requirements from USPS

The United States Postal Service (USPS) is implementing a new technology standard called Intelligent Mail Indicia (IMI) to modernize its mailing system.

What is IMI and why is it required?

IMI replaces the older technology and provides the USPS with more detailed and real-time data on your mailings. This translates to a smoother and more efficient mailing experience for everyone. Upgrading offers several benefits:

  • Reduced costs: Eliminates the need to guesstimate postage, preventing overspending and returns.
  • Improved cash flow: Detailed transaction data makes it easier to track refunds and reimbursements.
  • Always up-to-date: Your system automatically receives the latest postage rates and service information.
  • Enhanced security: Robust security features protect your data.
  • Increased efficiency: IMI streamlines mail processing for the USPS, potentially leading to faster deliveries.

What does this mean for you?

The good news is, you don’t need to take any action. Stamps is already working diligently behind the scenes to ensure our technology is fully compliant with IMI by December 2024.  As an approved USPS partner, we’ll make sure your mailing operation continues to run smoothly without interruption.

Don’t worry about IMI compliance with Stamps.com. Learn more
