What is a mailing and shipping rate change?

A rate change is a regular update to shipping prices made by carriers. These adjustments can happen for a variety of reasons, including fuel costs, inflation, operational improvements, or market demand. In some cases, carriers may also use dynamic pricing, where rates fluctuate based on factors like volume, capacity, seasonality, or delivery speed. Together, these updates help carriers remain competitive while continuing to invest in reliable service.

January 2026 changes

USPS has implemented rate changes effective January 18, 2026, which could impact your shipping costs. These adjustments primarily affect competitive package services, which are critical for high-volume shippers.

• Focused on shipping: Rate updates impact shipping services like Ground Advantage, Priority Mail, and Priority Mail Express.
• No stamp increases: First-Class Mail stamp prices will remain the same this January.
