Houston's college and university listings cluster in a few pockets more than others. Zip 77004 alone holds 34 of the 387 total listings, with 77005 close behind at 20 and 77204 at 17. Smaller clusters sit in 77002 with 7 and 77074 with 10, so if you're near one of these areas you'll find several options within a short drive rather than scattered across town.

Contact details are filled in for most entries: 349 listings carry a phone number and 307 have a website on file, though this category doesn't run paid placements yet, so any Sponsored tag added later will be clearly marked rather than blended into the regular order. None of these 387 listings are verified by SiteCity itself, so treat the directory as a starting point and call two or three before deciding where to apply or visit. If you run one of these schools and notice a wrong phone number or missing site link, you can claim the listing and update it, which helps the next Houston student find accurate information instead of a dead end.
