If a 01997 number called you
No clear pattern in reports for these numbers yet. If a call worried you:
- 1
Call back on a number you trust
If a caller says they're your bank, HMRC, a courier or a council, hang up and ring the organisation on the number from its website or your statement, never the number that called you. Caller ID can be faked.
- 2
Forward it to 7726
On a mobile, copy the caller's number from your recent calls and text it to 7726 (it spells SPAM). Scam texts can be forwarded to 7726 as they are. It's free, and your network uses the reports to investigate and block numbers.
- 3
Stop sales calls
Register your landline and mobile free with the Telephone Preference Service (0345 070 0707). Legitimate UK marketers must check it; calls should drop within 28 days. It won't stop scammers.
- 4
If you lost money or shared details
Call your bank on the number on your card (or 159 to reach most UK banks safely), then report it to Police Scotland on 101. In Scotland fraud goes to Police Scotland rather than Report Fraud.
01997 history and number format
Number format: Numbers on 01997 use Ofcom's 4+6 format: the 5-digit code (including the leading 0) followed by a 6-digit local number — written like 01997 234 567.
Before 1995: 01997 took its current form at PhONEday on 16 April 1995, when a "1" was inserted into every UK geographic code — before that the area dialled 0997.
Local dialling: Traditionally not from another 01997 landline, but it now depends on your provider: Ofcom stopped requiring providers to offer local (code-free) dialling on 11 March 2022. Dialling 01997 first always works, and mobiles always need it.
Allocation record: the oldest number block still visible on 01997 was allocated on 15 July 1994, and the most recent on 26 January 2026. 1 block was allocated in the last 12 months — newly-activated ranges with no call history, which is worth knowing when an unfamiliar 01997 number rings (see the weekly numbering changelog for every new allocation.)
