A range holder is the company Ofcom lists for a block of numbers, usually a network or wholesale provider that supplies many businesses. It is not evidence about the range holder or caller, and a displayed caller ID is not proof of who called. If a number rang once and cut off, do not call back.

What should I do after a suspicious call from a 01702 number?

What should I do after a suspicious call from a 01702 number?
StepAction
1Do not call back a number you cannot identify. If it rang once and cut off, that is often a test that your line is live.
2If the caller said they were your bank, a company or the police, hang up and phone the organisation on a number you find yourself, or call 159 for your bank.
3Forward suspicious text messages to 7726, free of charge.
4If you lost money or shared details, contact your bank at once and report to Action Fraud (England, Wales and Northern Ireland) or Police Scotland.
5For unwanted marketing calls, report to the ICO and block the number on your phone.
6Calls to 01 and 02 numbers are charged at your provider’s standard landline rate (gov.uk/call-charges).

Is a 01702 number real, and what does “Quarantined” mean?

Of the 1,000,000 numbers in 01702, 53.7% are allocated (537,000), 45.7% protected, 0.5% free and 0.1% quarantined in the snapshot published 23 Sep 2026, against 23.8% allocated across all UK geographic ranges. Quarantined means withdrawn and held before reuse, not never allocated; a block’s status does not tell whether one particular number is in service.

Has anything changed in the 01702 ranges, and which blocks were allocated recently?

Between the weekly Ofcom files fetched on 19 Aug 2026 and 24 Sep 2026 (5 weekly transitions), none of the 622 register blocks of 01702 changed status, holder or listing; the median active code also shows none. Separately, 1 blocks of 01702 have an allocation date in the last 12 months. Block changes are not the same as a number being cut off or ported.

Ofcom: “Please note that transferred numbers will also be shown as ‘allocated’.” (numbering data, ofcom.org.uk, retrieved 24 Sep 2026)
