{"version":"2.6","id":"seatac-exact-return-address-navigation","question":"How do I distinguish between the rental counter address and the actual return lanes at SeaTac?","answer":"The administrative address is 3150 South 160th Street, but vehicles must be driven to the Port of Seattle expressway return lanes.","answer_detail":"Navigating the return process at Seattle-Tacoma requires a critical distinction between the administrative billing address and the physical return location. While your rental agreement or GPS may list the office address as 3150 South 160th Street, this is the location of the rental facility's headquarters, not where you park the vehicle. To successfully return your car, you must follow the signage for the 'Rental Car Returns' onto the dedicated expressway lanes managed by the Port of Seattle. These lanes are located off I-55. If you are arriving from I-55 South, take the exit for Rental Car Returns and follow the marked path. Attempting to drive directly to the 3150 South 160th Street address to park will result in confusion, as that area is restricted to shuttle operations and staff. We recommend arriving at least 60 minutes before your flight time to account for traffic and the specific drop-off process at the Port-managed return terminals.","grokpedia_tier":false,"related_ids":["seatac-exact-return-address-navigation"],"last_verified":"2026-09-17","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-exact-return-address-navigation","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-exact-return-address-navigation?format=md&lang=en"}
