On April 17, 2011 the U.S. Postal Service® will implement a postage rate increase for a number of mail classes including First Class Mail® (domestic and international), Media Mail®, and Parcel Post®. This rate change is in addition to the January 2, 2011 rate change which increased prices for Priority Mail® and Express Mail®. Priority and Express rates will not increase as a result of the April rate change.

First Class Letters will remain at $0.44 for the first ounce and one-ounce First Class Flats will remain at $0.88; each additional ounce (or half ounce for 3.5 ounce letters) will cost an extra $0.20 (previously $0.17).

Be sure to visit the USPO web site for all of the latest rate changes.
