LEWISTON — The U.S. Postal Service says First Class mail deliveries to some parts of Maine that used to take one day will soon take two or three.

The Postal Service is changing its service standards beginning July 1. Maine USPS spokesman Tom Rizzo says delivery times are being changed as fewer people use the mail and the Postal Service tries to save money. It’s projected to run a $14 billion deficit this year.

The Lewiston Sun Journal says that now, a First Class letter mailed in Portland arrived in Aroostook County the next day. But after July 1 it could take longer.

But one-day delivery within certain groups of Zip Codes will still take a day.

The change will mean fewer trucks and fewer trips between Maine’s two processing locations.
