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

Dallas has 317 information technology companies listed here, and 29 of them sit in ZIP 75201 alone, with another 20 in 75243. If you work downtown or near Central Expressway, start calls with firms in those two ZIPs before widening your search to 75234 or 75248, where the counts drop to 20 and 21. Every listing includes a phone number, and 310 of the 317 link out to a website, so you'll rarely hit a dead entry regardless of which ZIP you're browsing.

None of these 317 companies is tagged Sponsored right now, since this category hasn't turned on paid placement, so the list you're scrolling reflects plain directory order, not a ranking or a review. If your firm shows up here with an outdated site link or a blank field, you can claim the listing and fix those details yourself, which matters most for a caller trying to reach you from a dense area like 75201. Use the ZIP counts as a starting point for proximity, then call two or three firms directly to compare scope and pricing before you commit to one.
