If a number from FUSION TELECOM LTD's ranges 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 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 FUSION TELECOM LTD is the range holder?
Ofcom allocated the blocks listed on this page to FUSION TELECOM LTD. 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 FUSION TELECOM LTD hold?
Of its 10 allocated ranges: 5 uk-wide (03), 3 freephone (080), 2 service (084/087). The oldest dates from 14 May 2020 and the newest from 14 May 2020.
How often is the FUSION TELECOM LTD list updated?
Ofcom publishes its numbering data every Wednesday and this page is rebuilt from it weekly, so new FUSION TELECOM LTD blocks appear within about a week.
