Waddington North America, A Novolex Brand

Houston's Business to Business listings cluster in a handful of ZIP codes. The 77041 area leads with 20 companies, followed by 77032 at 16 and 77040 at 13. If you're trying to narrow down where to start calling, those three spots hold the densest concentration in this category, with 77002 close behind at 12. Out of 263 total listings in this category, 258 list a phone number and 242 list a website, so most entries give you a direct way to reach the business without digging further.

Paid placements are labeled Sponsored, and right now this Houston category has zero of them, so everything you scroll through is unranked directory data rather than a bought spot. That also means no listing here has been checked or scored by SiteCity, so treat the phone number and site link as a starting point and call two or three before deciding who to work with. If you run one of these companies and see an outdated number or dead link, especially in the busier 77041 or 77032 clusters, you can claim the listing and correct it, which keeps a real inquiry from stalling on bad contact info.
