If a number from Sound Advertising Ltd's ranges called you
No clear pattern in reports for these numbers yet. If a call worried you:
- 1
Don't ring back to find out
Ofcom warns against returning missed calls from 070, 076, 084, 087, 09 and 118 numbers you don't recognise: a one-ring call that tempts you to call back can land you with premium charges. Check the full number here first.
- 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.

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.

Which area codes does Sound Advertising Ltd have most numbers in?
By allocated blocks: 0118 Reading (2), 020 London (1).
How often is the Sound Advertising Ltd list updated?
Ofcom publishes its numbering data every Wednesday and this page is rebuilt from it weekly, so new Sound Advertising Ltd blocks appear within about a week.
