Katy is a genuinely three-county city, and that shapes what "Katy" means for a shipment. The incorporated City of Katy sits near the point where Harris, Fort Bend, and Waller counties meet, and the wider Katy area extends well past the incorporated city limits into all three counties. In practice, that means Katy addresses carry several different ZIP codes; a carrier needs the exact pickup or delivery address, not just the city name, to route a shipment correctly.
I-10, the Katy Freeway, is the defining corridor. The stretch of Interstate 10 running from Houston's I-610 loop west through Katy, known locally as the Katy Freeway, was widened in 2008 and is widely cited as one of the widest freeways in the country. It's the primary route carriers use for Katy pickups and deliveries, continuing east into central Houston and west toward Columbus, Seguin, and San Antonio. The Grand Parkway (SH-99) connects Katy to the rest of the outer Houston metro, running roughly 15 miles from I-10 near Katy north to US-290 near Cypress. The Westpark Tollway links Katy to Fulshear and southwest Fort Bend County, running east-west through Cinco Ranch and Grand Lakes. US-290, which runs along Katy's Waller County side, is the corridor toward Hempstead and points northwest.
Katy includes large master-planned communities that can affect carrier access. Cinco Ranch, one of the largest and best-known master-planned communities in the state, sits within Katy's footprint along the Harris/Fort Bend County line. Communities like this often have HOA-controlled gates, guard entrances, or interior streets not built for a large multi-car carrier; if direct access isn't possible, a driver may need to meet at a gate or a nearby accessible street instead.
Katy is genuinely close to Cypress, Richmond, and Fulshear, but each is a separate community. Cypress sits north of Katy along the Grand Parkway/US-290 corridor. Richmond sits southwest, in Fort Bend County. Fulshear sits just southwest of Katy along the Westpark Tollway/FM 1093 corridor; Star Auto Shipping has a real, documented shipment with a Fulshear origin, see Fulshear, TX to West Lafayette, IN. These are separate cities and towns with their own pickup and delivery geography, not Katy neighborhoods.
