BREAKING NEWS!! The USPS™ Announces New Prices Starting August 29, 2021


As part of "Delivering for America", its 10-year plan to achieve financial sustainability and service excellence, the United States Postal Service™ filed notice, 5/28/21, with the Postal Regulatory Commission (PRC) for price changes to take effect August 29, 2021 that are in accordance with the rules recently established by PRC last year.  The new prices include:


A three-cent increase in the price of a First-Class Mail® Forever® stamp from .55 cents to .58 cents

Metered 1 oz. letters will raise from .51 cents to .53 cents with $.20 for each additional ounce

Commercial First Class Mail Postcard prices will increase .04 ea. to $.40 ea.

(Commercial First Class Mail Postcards will now be a maximum height of 6" and maximum length of 9" (previously 4-1/4" x 6").

A 1 oz. Flat will jump from $1.00 to $1.16 with $.20 for each additional ounce


Certified Mail will also be affected.  The Certified Mail fee and cost of Return Receipt are both subject to substantial increases.  Certified Mail is increasing .15 cents, from $3.60 to $3.75, while hard copy Return Receipt will increase .20 cents to $3.05 and electronic Return Receipt will increase to $1.85.


And other increases include Presort Letters (bills and statements), Marketing Mail, Periodicals (Newspapers, magazines, etc.), Package Services (Bound Printed Matter, Media Mail, Library Mail), Domestic Extra Services and Domestic Special Services (Including COD, Insurance, Money Orders, Return Receipt, Certified Mail, Signature Confirmation Services and more).


Prices not increasing in August from January are:  First Class Package Services, USPS Retail Ground, Parcel Select Ground and Parcel Select Lightweight (for now).


Prices will be increasing 10/3/21 - 12/26/21 for a TEMPORARY rate adjustment for the 2021 Peak Holiday Season Rate Increase for Priority Mail, Priority Mail Express, Parcel Select Ground and USPS Retail Ground.


  • $0.75 increase for PM, PME Flat Rate Boxes and Envelopes
  • $0.25 increase for Zones 1-4, 0-10 lbs.
  • $0.75 increase for Zones 5-9, 0-10 lbs.
  • $1.50 increase for Zones 1-4, 11-20 lbs.
  • $3.00 increase for Zones 5-9, 11-20 lbs.
  • $2.50 increase for Zones 1-4, 21-70 lbs.
  • $5.00 increase for Zones 5-9, 21-70 lbs.


It's time to think about presort prices:  With the right mail volume, you can take advantage of the USPS Presort discounts and pay only $0.433 for postage.  First Class Mail presorted postage may increase nearly 3 cents but sorting invoices, statements and bills by zip code is still advantageous and cost-effective.  Now might be the time to make it part of your mail prep process.


The price changes would raise overall Market Dominant product and service prices by approximately 6.9%.  First-Class Mail prices would increase 6.8% to partially offset declining revenue due to First-Class Mail volume declines.  In the past 10 years, mail volume has declined by 46 BILLION pieces, or 28%, and is continuing to decline.  Over the same period, First-Class Mail volume has dropped 32% and single piece First-Class Mail volume, including letters bearing stamps, have declined 47%.


"For the past 14 years, the Postal Service has had limited pricing authority to respond to changing market realities", said Postmaster General and CEO Louis DeJoy.  "As part of our 10-year plan to achieve financial sustainability and service excellence, the Postal Service and the Board of Governors are committed to judiciously implementing a rational pricing approach that helps enable us to remain viable and competitive and offer reliable postal services that are among the most affordable in the world."  Under the current pricing model and the proposed rate change, the Postal Service still has some of the lowest letter-mail postage rates in the industrialized world and continues to offer a great value in shipping.




In 2020, the Postal Service delivered approximately 129.2 BILLION pieces of mail and packages to customers located in every state and territory, county, city, town and rural area in the nation at over 161 million delivery points.
