According to my phone log, received 6 calls within 2 minutes from this number this morning. No msgs left, though I've apparently blocked this number in the past (so I'm not sure if a msg can be left). Some references to Kaiser (in Daly City) when googling. Maybe so, but possibly prerecorded messages that harrass us about procedures they want women (my wife) to have. I probably blocked it in the past because it became a nuisance. Hopefully I'm not missing any important messages about appointments, etc.

This is a normal number.  It's the Kaiser Specialty Pharmacy.  If they are calling, it's in regards to a prescription order or inquiry of some sort, and they need to talk to you before filling it.  It is NOT a spam number or used for advertising.
