2021 USPS Postal Rate Increase

Certified Mail Rates Rising in January 2021

The United States Postal Service (USPS) has Announced a Rate Increase for 2021 that will impact First Class Certified Mail, Certified Mail Return Receipt service, Priority Mail, and Express Mail services.   

The United States Postal Service filed a case with the Postal Regulatory Commission (PRC) to cause new postal rates to become effective at midnight on January 24th, 2021.

In summary, Certified Mail rates will increase to $3.60; if you purchase the Green Card Return Receipt Signature, you will add $2.85 to the Certified Mail cost plus your First Class postage or Priority Mail fee.  First Class rates will increase an additional $0.01 per Oz. The Electronic Return Receipt will cost $1.75

The new postal rates that were approved by the Postal Service Governors will raise postage rates for Priority Mail two and three-day delivery by approximately three and one-half percent (3.5%).  Next-Day Priority, Mail Express service, will increase by 1.5%. Many of the USPS postage rates will vary by product. USPS price increases are based on the consumer price index. Shipping Services prices are primarily adjusted according to market conditions. The Governors believe these new rates will keep the Postal Service competitive while providing the agency with increased revenue.


The PRC will review price increases for the price of a Small Flat-Rate Boxes to $8.45. Medium Flat-Rate Box would increase to $15.50, the Large Flat-Rate Box would increase to $21.90, and the price of the APO/FPO Large Flat-Rate Box would increase to $20.40. Regular Flat-Rate Envelopes, Legal Flat-Rate Envelopes, and Padded Flat-Rate Envelopes would increase to $7.95, $8.25, and $8.55, respectively. 

USPS noted that The U.S. Postal Service has some of the lowest letter-mail postage rates globally and continues to offer a great value in shipping. Unlike some other shippers, the Postal Service does not add surcharges for fuel, residential delivery fees and provides regular Saturday delivery.
