The United States Postal Service has approved a mid-year rate increase for letter mail, postcards and flats that will go into effect on August 29, 2021. This is the second time in 2021 that the USPS is increasing the postage rate. The first increase went into effect on January 24, 2021.

Why is this happening?
The Postal Regulatory Commission has completed a review of the rules that determine how much the U.S Postal Service can raise rates in a year. Now the Postal Service is exercising new pricing authority granted by the Postal Regulatory Commission in a November 2020 ruling that allows them to exceed the CPI-based price cap on market-dominant products to account for certain factors. To help the U.S Postal Service restore financial stability, the regulator decided it should have the ability to raise prices above the rate of inflation. The Postal Service decided to move up the rate change to help expedite their ability to generate new revenues rather than waiting until the traditional October announcement and January implementation date.

Listed below are the highlights of the proposed August 2021 U.S Postal Service rate increase:
  • Retail stamps and Forever® stamps are increasing 3¢ to $0.58.
  • Metered Mail letters increase 2¢ to $0.53, improving the metered letter savings to 5¢ per letter when compared to stamps.
  • Flats increase $0.16 to $1.16 for 1 oz.
  • Postcards increase $0.04 to $0.40.
