If a number from Calltracks Limited's ranges called you

No clear pattern in reports for these numbers yet. If a call worried you:

  1. 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. 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. 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.

    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 Report Fraud online or on 0300 123 2040. Report Fraud replaced Action Fraud on 4 December 2025 for England, Wales and Northern Ireland; in Scotland call Police Scotland on 101.

Frequently asked questions

What does it mean that Calltracks Limited is the range holder?

Ofcom allocated the blocks listed on this page to Calltracks Limited. A number keeps its digits when its user switches provider, so a number in these blocks may now be on another network; Ofcom doesn't publish who a number is on today.

What kinds of numbers does Calltracks Limited hold?

Of its 464 allocated ranges: 436 landline (01/02), 15 service (084/087), 9 uk-wide (03), 4 freephone (080). The oldest dates from 22 July 2013 and the newest from 12 January 2022.

Which area codes does Calltracks Limited have most numbers in?

By allocated blocks: 028 Northern Ireland (8), 01282 Burnley (5), 01296 Aylesbury (5), 01332 Derby (4), 01772 Preston (4).

How often is the Calltracks Limited list updated?

Ofcom publishes its numbering data every Wednesday and this page is rebuilt from it weekly, so new Calltracks Limited blocks appear within about a week.
