Each bar is the number of distinct IPs that searched NoCall (web or app) for any number with this prefix that day (UTC days); an IP counts once a day however many numbers it looks up, and it may be a bot. Days without a complete measurement are left empty. Reports are only those sent by NoCall users and approved after review (no imported data or comments), counted per distinct user, and are shown from 3 users. A lookup does not mean the number is a scam. Updated on 7 Nov 2026
