The United States Postal Service put new mailing and shipping prices into effect on Sunday, lifting the cost of a First-Class Mail Forever stamp by 5 cents to 78 cents. The increase, cleared by the Postal Regulatory Commission earlier this year, represents a 7.4% jump for first-class letters and is the latest in a series of semi-annual adjustments. Beyond ordinary letters, domestic postcard stamps now cost 61–62 cents, while metered one-ounce letters rise to 74 cents. Parcel prices are also higher: Priority Mail climbs roughly 6.3%, USPS Ground Advantage 7.1%, and Parcel Select 7.6%. Rates for Priority Mail Express remain unchanged. USPS said the higher charges are necessary to meet the financial targets of its 10-year “Delivering for America” overhaul, which aims to restore the agency to long-term solvency as traditional mail volumes decline. Senior spokesperson Marti Johnson described the move as a “rational and realistic approach,” noting that U.S. letter prices remain lower than those in many other countries.
