I’m scanning some color negative film and realized I didn’t record what stock I used. The strip doesn’t clearly show the film name, but it does have edge markings and numbers such as “EJ 06 3677 9344,” along with some symbols like * and $. The perforations also look a bit unusual. Can film stock be identified from these edge codes, and if so, what does this one indicate?

Yes. Film stocks can often be identified from the edge markings printed along the rebate. Those numbers and symbols are not random; they’re manufacturer identification codes. Kodak uses edge codes/KeyKode markings that can be matched against published reference lists.
Based on the codes you provided, the film is Kodak Vision3 500T. That is a tungsten-balanced color negative motion-picture film.
The unusual perforation shape also fits the possibility that this is cine film rather than standard still-camera film. If you’re scanning it as still negatives, that can explain why the markings don’t look like the usual consumer still-film branding.
So in general: if a film strip has rebate numbers, symbols, or KeyKode-style markings, you can identify it by comparing those markings to a Kodak or film-ID reference chart. In your specific case, the community answer identifies it as Vision3 500T.
