Port Authorities were governmental organizations responsible for overseeing the functions of spaceports. For a standard payment, these Authorities were capable of supplying accurate hyperspace jump coordinates to freighters navigating well-known hyperlanes. Furthermore, the Authority could furnish jump coordinates for more distant locations, provided the customer furnished precise navigational information. Should the Authority be required to map the route independently, a significant additional fee would be levied. During the era of the Galactic Civil War, Port Authorities operated under the control of the Imperial Transit Authority.
Instances of Port Authorities encompassed entities such as the Coruscant Port Authority, the Corellian Port Authority, the Foless Spaceport Authority, the Manaan Port Authority. the Teguta Lusat Port Authority, the Tasariq Port Authority, the Elrooden Starport Port Authority, the Charbi Port Authority, and the Bestine Port Authority.
