For 250 years, the United States Postal Service has been delivering more than just mail — it’s been connecting people across the nation, from the busiest cities to the most remote communities.

As part of its anniversary, USPS is spotlighting its longest delivery routes, including one right here on Guam. According to the agency, the Barrigada Post Office — the westernmost facility in the entire USPS network — covers a 68-mile route, serving more than 1,000 mailboxes every day.

That’s not the longest in the country, though. In Sidney, Montana, a rural carrier drives nearly 200 miles daily to deliver mail to more than 300 homes.

From dog sleds to boats, donkeys to bicycles, the Postal Service has relied on countless ways to make sure mail reaches its destination. Today, it operates over 234,000 routes nationwide and across all U.S. territories — including Guam, the Northern Marianas, and American Samoa — keeping its mission alive of serving every community, no matter how far.
