Most biotechnology listings in San Diego sit in one zip code. Of the 86 total listings, 56 are in 92121, with smaller clusters in 92126, 92130, 92127, and a few others scattered across the city. If you're narrowing a search, start in 92121 first since it holds by far the most options. Of the full set, 84 listings have a phone number on file and 82 list a website, so you can check details online before dialing.

None of these listings carry a verified badge, and none are sponsored right now, so this is the complete unranked list rather than a curated one. Should paid entries appear here later, they'll display the word Sponsored right on the card so you can tell them apart. If you run one of these companies and spot a missing phone number or website, you can claim the listing and update it yourself, which helps a caller in 92121 or a nearby zip reach you on the first try. Call ahead or check the listed site before visiting, since details can shift.
