CS was established in 1957 in Tokyo, Japan, when a consortium of newspaper publishers formulated the concept of a worldwide speed delivery network for their publications. Their invention was called "Overseas Courier Service Co., Ltd."

Since then, OCS has been providing premium quality express courier, freight forwarding, transportation and logistic solutions worldwide. Major OCS corporate offices worldwide anchor one of the most extensive international delivery systems ever developed.

It was in 1986 that OCS Pakistan (Pvt.) Ltd. first started operations as an independent courier company in Pakistan. In the wee hours of a crisp winter morning, the first express document was booked in Karachi. What followed is history. Today, OCS Pakistan handles tens of thousands of shipments every single day. Within Pakistan, the OCS name has become synonymous with dependability and quality. It has 212 pickup points and more than 1500 delivery locations across Pakistan. Internationally it covers the globe with the OCS network of over 240 offices in more than 90 countries around the world.

OCS is committed to provide high quality services that are reliable, time sensitive and effective catering to all courier needs of both local and international customers.
