The United States Postal Service allows customers to contact the company regarding internationally shipped packages that are lost, damaged or missing contents. USPS has its own International Inquiry Center to handle inquires regarding international packages. Once you become aware of an issue with an internationally shipped package, contact the USPS International Inquiry Center immediately to rectify the problem.
Call the USPS' International Inquiry Center at 800-222-1811 to speak to a USPS customer service representative regarding an internationally shipped package.
Provide the USPS representative with the shipping number located on the receipt you were given when you mailed your package as well as the names, addresses and contact information of both the shipper and the recipient of the package.
Inform the USPS representative of the problem with the international package you are inquiring about, such as whether the package is lost, missing items or damaged. A solution may take up to several business days; USPS will contact you regarding the outcome of your inquiry or complaint.
The USPS requires you wait at least three business days after the date the package was mailed -- business days are Monday to Saturday each week -- before calling about Global Express Guaranteed, Express Mail International and Express Mail International with Guarantee mail. Do not wait longer than 30 days from the date of mailing to call about Global Express Guaranteed or Express Mail International with Guarantee Mail. Do not wait longer than 90 days to call regarding Express Mail International mail. Wait at least seven business days to call about Priority Mail International and Registered Mail Services mail, but not more than six months.
