601 businesses listed, showing 1–40. How we order them.

Houston's information technology company listings cluster around a handful of ZIP codes. The 77042 area leads with 39 entries, followed by 77002 with 29 and 77057 with 25. If you're comparing options, start by narrowing to the ZIP closest to your office, then call two or three firms directly rather than scrolling the full list of 601.

Contact details are filled in for most of these listings: 593 have a phone number and 570 list a website. Paid placements are labeled Sponsored when a business pays for one, but no listing in this category currently holds that status, so what you're browsing is plain, unpurchased directory order. If you run one of these Houston IT companies and notice a wrong number or a broken site link in 77024 or 77036, you can claim the listing and fix it yourself, which keeps a real lead from bouncing off a dead contact.
