# Known Shipper

Known shipper is a shipper status determined by the TSA (Transportation Security Administration). A shipper must be a known shipper in order to load cargo on a passenger aircraft from the US.

## What is a known shipper?

Known shipper is a shipper status determined by the TSA (Transportation Security Administration). A shipper must be a known shipper in order to load cargo on a passenger aircraft from the US. TSA's [Known Shipper Management System](https://www.law.cornell.edu/cfr/text/49/1548.17) confirms the validity and integrity of the shipper to establish the shipper as a known shipper.

Known shippers also have better freight rates, more route options, and fewer delays as a result of being an established shipper with the TSA.
