Blocking a number is a household tool, not a court process. It stops that line from ringing you on that handset. It does not prove a crime. It does not identify a private person. It does not stop a fraudster from spoofing a fresh display. Use blocking to get peace. Use official reporting if money, threats, or fraud are involved.
You can combine handset blocks with network tools, landline features, and the Telephone Preference Service at tpsonline.org.uk. None of these is perfect. Together they cut a lot of noise.
iPhone: Recents to Block this Caller
Open the Phone app and go to Recents. Tap the information icon beside the call. Scroll to Block this Caller and confirm. The number should no longer ring through on that iPhone. You can review blocked contacts in Settings under Phone.
If they left a voicemail, you can still block from the same info screen. Blocking does not delete the history. Keep a note of the number if you plan to search it on WhoCalledMe or mention it to your bank.
Silence Unknown Callers is a separate iPhone setting. It sends unidentified numbers to voicemail. That can help with random pings. It can also hide a call you actually wanted. Use it with care. It is not a fraud verdict on every withheld line.
Android: Recents to Block or report
Open Recents in the Phone app. Tap the call, then look for Block, Block/report, or a similar label. Wording varies by manufacturer, but the idea is the same. Confirm the block. Some Android phones offer a spam list or a “filter suspected spam” option from Google or the manufacturer.
Network apps from EE, O2, Vodafone, and Three may add extra blocking or spam labelling. Open those from the official app store and sign in to your account. They cannot see a spoofed caller’s true identity just because you tapped Block.
If a blocked number still appears, the display may have changed. Treat it as a new line. Block the new one too. Search both on WhoCalledMe.
Landlines and provider nuisance tools
Home phones still receive a large share of nuisance calls. BT, Virgin Media, and other landline providers offer nuisance-call blocking, anonymous-call rejection, or extra-digit codes to refuse a last caller. Features differ by package. Use the help pages you reach by typing the provider’s address yourself, or the booklet that came with the service.
A simple landline handset may only store a small block list. A provider-level tool can catch more. Neither list proves that the people behind the calls committed an offence. CLI spoofing means an “01” neighbour-looking number might not be a neighbour at all.
If elderly relatives use the landline, sit with them once and block the worst repeaters together. Agree that they can hang up without a speech. Practise using 159 for bank worries so a blocked-call list is not their only defence.
Network tools, TPS, and what they miss
Mobile networks offer spam protection, caller alerts, and sometimes extra block lists. Try the tools from EE, O2, Vodafone, Three, or your virtual network, through official channels. Broadband providers such as BT and Virgin Media may bundle call-screening for home numbers.
Register with the Telephone Preference Service for live sales. TPS does not stop scams, recorded blasts, or every overseas operator. The ICO can take a plain-language complaint if live marketing continues after you said no and after TPS registration. Ofcom sits in the background of numbering and silent-call policy. Action Fraud is for fraud. 999 is for emergencies. 101 is for non-emergency crime.
Apple Pay, banking apps, and email are not blocking tools. If a call pushed you to approve a payment, deal with the bank first, then block.
Blocking does not prove a crime
It is tempting to treat a blocked list as a list of offenders. That overstates what a handset knows. Numbers are reused. Displays are spoofed. A small business can be displayed without being at fault. WhoCalledMe cannot name a private mobile owner from CLI. Your block list should stay private and practical.
When you report on WhoCalledMe, stick to what happened. Time, number, what they asked. Do not paste a screenshot of your entire recents list if it includes family. Do not claim the blocked caller “is a criminal”. Say it was a suspected scam script or unwanted sales, as appropriate.
If money moved, blocking is secondary. Call the bank on 159 or a number on your card. Tell them if it may be APP fraud. Report to Action Fraud. GOV.UK Stop Think Fraud is there for the pause before the next call.
When they come back on a new number
Rotation is normal. You block one line. An hour later a new number reads the same bank, parcel, or PPI script. Block the new number. Search it. Add it to the same WhoCalledMe report as the earlier ones. One report with several numbers shows the pattern without scattering the story.
If they used a landline display and then a mobile, include both. If a robocall and a live follow-up used different lines, include both. Ask others in the household to add numbers they saw, on that same report, without naming neighbours as suspects.
Keep blocking. Keep notes short. Use official routes for harm. A quiet phone is the aim. A guilty verdict is not something your Recents menu can issue.
Common warning signs
- The same number rings several times a day.
- Calls continue after you have asked to be removed.
- A new similar number appears as soon as you block one.
What you should do
- Block the number on your phone.
- Register with the Telephone Preference Service for live sales calls.
- Tell your landline provider if you have a home phone.
- Report the number on WhoCalledMe so other people can see the pattern. Add other numbers from the same script.
- If calls include threats or fraud, contact the police on 101 or 999 in an emergency, and Action Fraud for fraud.
