Will Postage Rates Increase in 2021? (Updated December 2020)

Going to the Post Office is never fun. It’s even less fun if your trip results in higher shipping rates. Last October, the US Post Office had announced its intention of a postage rate increase. The new rates were to go into effect on Sunday, January 24, 2021.

The Postal Regulatory Commission (PRC) has accepted the 2021 proposed postage rate increase (as of December 2020). The Postal Service Board of Governors believes that this price increase will keep the USPS competitive and provide much-needed revenue. The rate increases are mostly based on the consumer price index, however, the competitive International Shipping Services prices are increased according to market conditions. Because these rates haven’t been approved yet, this means that the US Post Office could still have their rates increase or decrease or not change at all pending review of the PRC.

In the meantime, however, FedEx and UPS have also announced a postage rate increase at the beginning of the year. FedEx will raise pricing by an average of 4.9% beginning January 4, 2021.

Not all postage will be affected, so read on for some good news.

The bad news is that almost all rate types will be impacted by the increase. Some rates will see a higher increase than others, with specific rates reaching hikes of 9.9%.

Before we look at the rate increase details for the US Post Office, let’s take a look at some good news:
