Price of a P.O. Box Going Up June 8

People renting post office boxes, sending certified mail or buying postal insurance will find new services and changed rates starting June 8. The Postal Service’s board of governors also decided to set up a system to provide confirmation of delivery, starting in big cities, for Priority Mail, parcels, international shipments, certified and registered mail, as well as the current Express Mail. Rate changes to take effect in June will raise the cost of a certified letter from $1.10 to $1.35. The cost of renting a business post office box will rise from $310 a year to $372 a year in Los Angeles, Boston, Philadelphia, Washington, Chicago, San Francisco and Honolulu.
