San Antonio's real estate agents cluster heavily in a few ZIP codes. 78258 leads with 135 listings, followed by 78232 at 83 and 78249 at 76. If you're comparing agents in a specific part of town, start with the ZIP where most of them work, since a cluster of 135 gives you far more options than a pocket with only a handful on file.

This page lists 1054 real estate agents across the city, and 1040 have a phone number listed, so calling ahead is usually straightforward. Not every listing links to a website, and none of these entries are marked Sponsored right now, so the order reflects what's on file rather than a paid spot. Call two or three agents in your target ZIP before settling on one, since proximity to your neighborhood often matters more than firm size. If you run one of these agencies and spot a wrong phone number or outdated website, claim the listing and fix the details yourself.
