How to check someone before a first date

By the StoryCheck team · 6 min read · Published 29 September 2026

Before a first date in the UK, three checks do most of the work: confirm the person is real (a short video call and a reverse image search of their photos), check that the number they gave you fits their story (a UK mobile, a WhatsApp photo that matches, public profiles in the right place), and plan the date so you stay in control (a busy public place, your own way home and a friend who knows where you are). None of this is suspicion. It is ordinary care, and a genuine match will understand.

What is worth checking before you meet?

How do you check they are who they say they are?

Start with a video call. Tinder's own UK safety advice calls a phone or video call a useful screening tool before meeting, and a genuine match will usually agree to five minutes. Then run each of their profile photos through a reverse image search: the same picture under another name, or on a model's account, settles the question. If they have told you their surname and job, a quick search will normally show a real person, for example a LinkedIn profile or a mention on an employer's website.

Keep the conversation in the app until you have done this. Tinder notes that people with bad intentions often try to move to text or messaging apps straight away, away from the app's own safety checks, and it may show a safety alert when it detects contact details being shared. When you do swap numbers, the number gives you something extra to check, and our guide to spotting a fake profile goes further on photos and stories that do not add up.

What can their phone number show you?

A private number lookup checks the number they gave you in about 60 seconds, and they are never notified. It shows the line type, so you can see whether it is a UK mobile or a VoIP or virtual line, the network, whether it is active on WhatsApp with the profile photo when their settings allow it, public profiles and web mentions openly linked to it, and any scam signals. On a private UK mobile a name is often not available, so treat the report as a consistency check: does the photo match, and do the profiles fit the person you have been talking to?

Dating is one of the main reasons people check a number at all. In StoryCheck lookup data from July to September 2026, 30% of people in the UK who checked a number said dating app activity was what they most wanted to know about.

How do you plan the date itself?

• Meet somewhere busy and public, and stay in public: Tinder's own advice is never to meet at your home, their home or any other private place.
• Tell a friend where you are going, who with and when, and share your location with them using your phone's built-in features or WhatsApp's live location.
• Sort out your own way there and back, so you can leave whenever you want.
• Keep your drink where you can see it, and your phone charged and with you.
• Know about Ask for Angela. At participating venues, asking staff for 'Angela' tells them quietly that you need help, and trained staff can help you leave, support you to stay or call security. The scheme's website has a map of venues.
• If you are in danger, ring 999. If you cannot speak on a mobile, listen to the operator and press 55 when prompted, and your call is put through to the police.

What if something feels wrong before or after?

• Cancel if the story keeps changing or the pressure builds. You owe nobody a first date.
• Block and report them in the app, from their profile or the chat, so the app can review the account.
• If they will not leave you alone afterwards, the National Stalking Helpline, run by the Suzy Lamplugh Trust, is on 0808 802 0300. Report threats or harassment to the police on 101, or 999 in an emergency.
• If the relationship develops and you are worried about a new partner's past, Clare's Law lets you ask the police in England and Wales whether they have a history of domestic abuse. Scotland has its own Disclosure Scheme for Domestic Abuse Scotland (apply online, at a police station or on 101), and in Northern Ireland the PSNI can advise.
• If a match asks for money at any point, before or after you meet, stop and read our guide to romance scam signs.

Is it OK to look someone up before a date?

Yes, for your own safety, and the check is private. A lookup reads publicly available information and licensed sources, for personal use such as confirming that someone you are about to meet is who they say they are. Keep it proportionate: you are confirming an identity, not researching a past, and results must never be used for decisions about credit, employment, insurance or letting a property. If the checks come back clean, stop checking and go and enjoy the date.
