USPS Service Alerts

Last updated June 24, 2016, 2 P.M. ET

USPS Service Alerts provide information to consumers, small businesses and business mailers about postal facility service disruptions due to weather-related and other natural disasters or events. Service alerts are done in near real time.

Residential customers and small businesses can use this website to learn if mail is being delivered, or if their Post Offices are open. Business mailers are provided more detailed information about USPS mail processing facilities, and the operating status of postal delivery units.

Severe flooding in Appalachian region

Recent storms in the Appalachian region have caused a temporary disruption to service.  Heavy rains have caused flooding, making many roads impassable and offices unreachable.  The Post Office is monitoring conditions in the region and making provisions to continue to provide customers with retail and delivery service where it remains safe to do so.

Specific office closures and delivery impacts can be found on the links “Is my Post Office open?” and “Will I receive mail delivery?”  Please continue to check back for updates.

Lithium battery shipping regulations

U.S. Postal Service acceptance of international lithium battery shipments

The Postal Service is now allowing specific quantities of lithium batteries — when installed in the equipment they are intended to operate — to be sent to many international destinations, including Army Post Office (APO), Fleet Post Office (FPO) and Diplomatic Post Office (DPO) locations when permitted by the destination or host country.

The postal operators of Germany and Italy are not accepting packages containing lithium metal or lithium-ion batteries to German or Italian addresses. Postal employees will decline electronic items containing lithium batteries to addresses in those two countries. This does not apply to shipments to and from German or Italian APO, FPO or DPO locations.

Items that can be shipped include: cameras, video cameras, mobile/smart phones, Bluetooth headsets, laptop computers, shavers, portable DVD players, tablets, two-way radios, GPS devices and most other small electronic devices requiring lithium batteries. Items that can’t be shipped include lithium batteries not installed in the equipment they are intended to operate. In addition, when installed, they may not exceed the quantity or limits defined in the IMM or DMM.

Domestic shipments of packages containing lithium batteries, and electronic devices containing lithium batteries aren’t affected.

Currently, U.S. customers aren’t permitted to take international and APO, FPO, DPO mail containing lithium batteries to Village Post Offices, contract postal units, commercial mail receiving agents or approved USPS shippers. For more information, click
