What to do if…
a stranger tries to get you to reveal your phone number by calling it from their phone on the spot

Short answer

Create distance, keep hold of your phone, and calmly refuse the “call it now” request. If you want to stay polite, offer a safer alternative (take their number instead or connect via an app).

Do not do these things

Don’t hand your phone over “just for a second” or let them type on it.
Don’t unlock your phone and place it within their reach.
Don’t read out or show any codes that arrive by text (verification/security codes).
Don’t stay put while deciding — move toward people/exit first.
Don’t argue about whether it’s “a scam” — keep it brief and end the interaction.
Don’t follow them somewhere quieter to “sort it out”.

What to do now

Shift to safety before you respond. Step back, angle your body toward an exit/crowd/shop, and keep your phone in your hand or pocket (not held out).
Use a short refusal you can repeat. “No, I don’t share my number.” / “Sorry, I can’t do that.” Repeat once, then stop engaging.
Offer a safer alternative only if you genuinely want to.
- Take their number (on paper or in your notes) and say you’ll contact later if you choose.
- Suggest a method that doesn’t expose your number (message on the platform where you met, or exchange usernames/QRs you control).
If they escalate (anger, blocking your path, grabbing, following): end the conversation and go to staff/security or a busy counter immediately. If you feel in immediate danger, call 999.
If your phone already rang and they now have your number: once you’re away, block the number. Consider silencing unknown callers or turning on spam filtering.
If any texted “code” arrives during/after this: treat it as a red flag. Do not share it. Check your key accounts (email, banking, messaging) for unexpected sign-in prompts and secure them if anything looks off.
If suspicious messages follow:
- Forward suspicious text messages to 7726 (free) to report them to your mobile provider.
- Forward suspicious emails to the UK phishing reporting inbox (don’t reply to the sender).
Report if appropriate (once you’re safe).
- England/Wales/Northern Ireland: report fraud/cybercrime via the police-run national “Report Fraud” service (online/phone).
- Scotland: report to Police Scotland (101 for non-emergency, or online reporting for non-urgent matters).
- If it was harassment or a public safety incident, you can also contact police via 101.

What can wait

You don’t need to decide right now whether it was “definitely a scam” or “just awkward”.
You don’t need to explain your refusal or justify your privacy boundary.
You can review longer-term privacy options later (call screening, who can add you on apps, whether to use a secondary contact method).

Important reassurance

It’s reasonable to treat forced “on the spot” contact-sharing as a safety issue. You’re allowed to say no, leave, and prioritise your comfort without proving anything.

Scope note

This is first-steps guidance for the moment and the next hour or two. If you keep being targeted, or the person knows where you live/work, you may need tailored advice from police or a specialist support service.

Important note

This is general information, not legal advice. If you feel unsafe or threatened, prioritise getting to a safer place and contacting emergency services.
