United Parcel Service Inc. is resuming the remainder of its services halted in Iwate Prefecture after the March earthquake and tsunami.

Pickups and deliveries in the affected areas restarted Monday, spokeswoman Susan Rosenberg said. Fukushima is the only prefecture where some UPS services remain suspended, she said.

The restoration "has to do with businesses and our customers getting back to work in those areas so that they're going to be shipping and receiving," Rosenberg said.

She didn't know whether government restrictions have affected the company's timetable for restarting.

UPS resumed pickups and deliveries in eastern parts of Japan five days after the disaster, but it didn't stop flying planes in and out of the country. The world's biggest package delivery company has not disclosed the earthquake's financial impact.

UPS has 1,000 employees in Japan and 34 weekly flights to and from the country, with 10 pickup and delivery centers plus other centers for operations, logistics and brokerage services, the company said in March.

About a quarter of UPS' $49.5 billion in sales last year came from international markets, and volume on international packages jumped almost 14 percent, or about seven times as much as deliveries within the U.S.
