Why numbering changes matter for caller identification
A phone number's range holder is fixed at allocation — so when a block appears here, calls from those numbers are brand new to the UK network. Newly-activated ranges are disproportionately used for outbound campaigns (legitimate and otherwise) precisely because they have no reputation history. If an unfamiliar number that called you sits in a recently-allocated block below, that's worth knowing — look the full number up to see the range holder and any verdicts other callers have left.
