Long-Distance Moving from Seattle
An interstate move out of Seattle — to Portland's far side, to California, to Texas — falls under federal jurisdiction the moment your belongings cross a state line. That changes the pricing model, the paperwork, and your rights as a shipper.
This page covers the fundamentals every Seattle household should understand before collecting interstate quotes.
How interstate pricing actually works
Long-distance moves are priced primarily on two inputs: how much your shipment weighs (or its cubic volume) and the line-haul distance to the destination. On top of that base come accessorials — packing services, shuttle trucks where a semi can't reach the door, stair or long-carry charges, and storage-in-transit if your new home isn't ready.
Because weight drives cost, the single most powerful lever you control is shedding belongings before the survey. Every bookshelf you sell in Seattle is weight you never pay to haul over the Rockies.
Binding, non-binding, and binding-not-to-exceed
Interstate estimates come in three flavors, and the flavor matters more than the number. A non-binding estimate is a guess — your final bill follows the actual weight, up or down. A binding estimate locks the price to a defined inventory, protecting you from surprises but also from savings if you bring less. Binding-not-to-exceed is the shipper-friendly hybrid: the quoted price is your ceiling, and if the actual weight comes in lower, you pay the lower figure.
Whatever the type, an estimate is only as good as the survey behind it. A quote issued after a video or in-home walkthrough of your actual belongings means something; a number produced from a two-minute phone call does not.
Verify before you sign: USDOT and FMCSA
Every legitimate interstate mover holds a USDOT number and operating authority from the Federal Motor Carrier Safety Administration. The FMCSA's public mover registry lets you look up any company's registration status, complaint history, and whether it's a carrier that owns trucks or a broker that resells your move to someone else. Run that lookup on every company that quotes you — it takes minutes and filters out most of the industry's bad actors.
Brokers aren't automatically bad, but a broker presenting itself as a carrier is a red flag, because you won't know who actually shows up with the truck. Ask directly: 'Are you the carrier, and will your trucks and employees perform this move?' The hesitation tells you as much as the answer.
Before accepting any interstate quote
- Look the company up in the FMCSA mover registry by USDOT number
- Confirm whether they're a carrier or a broker, in writing
- Insist on a video or in-home survey, not a phone estimate
- Get the estimate type (binding / non-binding / not-to-exceed) stated on paper
- Treat large upfront deposits as a walk-away signal
