How the monthly snapshot is built
On the 1st of every month our cron job aggregates the previous month's lookups across the free UK Number Checker, groups by national number, picks the top 50 by search volume, and writes them to this monthly snapshot. The list is then frozen — it won't change as new lookups happen in later months, so this page becomes a stable historical record of the period's nuisance-call landscape.
