Questions about the San Mateo list
Where does this data come from?
The California attorney registry, which the state publishes as a public record. We do not buy or merge third-party compiled lists.
Does every row have an email address?
No — and no honest attorney list has one for every row. The roster on this page carries no email column at all. We hold addresses for 25 attorneys in San Mateo (19%), sold as the San Mateo email file above.
Where do the email addresses come from?
The California registry does not publish email addresses, so ours are read from firms' own websites and then matched back to a licensed attorney by name. Either way an address is only sold once it belongs to a named, currently-licensed attorney.
How current is it?
Last refreshed 2026-09-06 — that is the date of the scan behind these figures, not a promise of a schedule.
