The Barbados Postal Service (B.P.S.) is the island's national postal operator and is a department of the Barbados Government that reports to the Ministry of Home Affairs. The acting Postmaster General, Sheila Greaves, is in charge of maintaining the island's postal services in accordance with the laws of the island. After local legislation allowing for the delivery of inland postage, Barbados's postal services were reorganized in 1852.

The Post Office Act grants the postal service authority to process express mail and parcel post items independently of HM (Barbados) Customs. This authority extends to the collection of duties and taxes for low-value, low-dutiable items on behalf of HM (Barbados) Customs.
