How to Do a Background Check on Someone Before You Meet Them

Most people decide whether to meet a stranger from a dating app based on how the conversation felt.

That instinct isn't a great filter. Romance scams now carry the highest median dollar loss of any scam type tracked by the Better Business Bureau, coming in at $6,099 per victim, which is even more than investment or cryptocurrency fraud. BBB calls the underlying mechanism "financial grooming," where a scammer spends weeks or months building trust before asking for money.

Tinder, Hinge, Bumble, and other major apps have added optional photo or ID verification in recent years, but verification isn't universal, and a verified badge on one platform doesn't carry over once a conversation moves to text or email. This guide is for that gap. The person behind a convincing profile, a weeks-long conversation, and a first date that seems to go well can still be operating under a false name, hiding a criminal record, or running the same script on a dozen other people simultaneously.

Knowing how to do a background check on someone doesn't require a private investigator or a paid screening service. It just requires data points you probably already have, like a name, a phone number, or maybe an email address. You'll also need the right tools to run them against public records. Here's the full process.

What a Background Check on Someone Actually Checks For

A pre-date background check is about confirming that the person presenting themselves to you is who they say they are, before you're sitting across from them.

If you want the full breakdown of what a background check can and can't surface, our guide to what a background check shows covers that in depth. Here, the focus is the five-step process for running one yourself, using only the information you already have.

How to Do a Background Check on Someone: 5 Steps

Step 1: Run Their Name Through a People Lookup

A name is your broadest starting point. Running it through a people lookup may surface address history, associated phone numbers, known relatives, and publicly linked profiles tied to that name.

What you're cross-referencing is simple:

• Does the city they mentioned match the address history?
• Does the age they gave you align with what public records show?
• Does the name come back at all, or does it return nothing, which, for a person with any normal digital history over the age of 25, is unusual?

A thin or absent result for someone who claims to have lived in a city for years is a signal worth noting. Real people accumulate public records like lease agreements, voter rolls, property filings, and phone registrations.

Step 2: Reverse Lookup Their Phone Number

If someone has given you a phone number, or one appears in your messages, a reverse phone lookup queries publicly available data tied to that number, such as registered owner, carrier type, and a location.

Here, the carrier type matters as much as the name. A mobile number registered to a real person under their actual name reads very differently from a VoIP line, like Google Voice, TextNow, or Burner, which indicates a number created specifically to avoid being tied to a real identity. People who use dating apps for legitimate reasons have real phone numbers. Someone whose contact number comes back as a VoIP line with no identity attached has gone out of their way to be untraceable. 

If the name that comes back from a phone lookup doesn't match the name you were given, you have a direct inconsistency to resolve before the first meeting.

Step 3: Check the Email Address

Dating app conversations that move to a separate platform almost always involve an email address at some point. A reverse email lookup may surface the name associated with that address, linked social profiles, and usernames across platforms. A long-standing email address used across multiple services over years is a good sign.

The secondary signal is the username portion of the address (the part before the @). Run it as a search across platforms. Consistent usernames that match an established identity are a positive signal, but a username that appears only on platforms is something to pay attention to.

Step 4: Reverse Image Search Their Photos

Every photo someone shares with you before a first meeting can be run through a reverse image search to check whether it appears elsewhere online under a different name or account. This is the fastest way to identify a stolen photo.

Upload each photo to Google Images, TinEye, and Yandex. Google catches stolen photos from indexed social profiles and websites. TinEye is strongest for finding the original source of a photo used across multiple fake profiles. Yandex indexes a significantly wider range of international social media content and catches sources the other two miss. You should run all three.

A clean result across all three used to mean a photo was probably safe, but that's no longer reliable. AI-generated faces won't return any results, because the photo has never existed anywhere else online to begin with. That means a search that comes up with nothing is now a reason for more scrutiny. Our articles, “Romance Scammer Photos: Why Zero Results No Longer Mean the Photo Is Real” and “How to Reverse Image Search a Catfish” cover what the additional tests look like.

Step 5: Check for Criminal Records and Court Filings

Court records are public in the United States and surface in people search databases. A background check run through a public records aggregator may return arrests, convictions, civil judgments, and restraining orders attached to a name. Depth may vary by state, as some jurisdictions make records more accessible than others, but most states surface at least felony convictions and active restraining orders.

Public records searches have real limits, such as expunged and juvenile records, dismissed cases, and identity-matching for common names are covered in full in what a background check shows. Treat anything you find as a starting point for further verification rather than a verdict.

Red Flags Checklist: When One Inconsistency Becomes a Pattern

A single inconsistency isn't necessarily meaningful on its own. People move, records have errors, and a thin result for a private person isn't proof of anything. You need to pay attention to whether those inconsistencies stack up.

One or two items in the red-flag column are usually explainable on their own. Several together, like a VoIP number, an email with no history, and photos that return results under a different name, become a pattern.

If something surfaces that concerns you, document it before reaching out. Screenshot your results with timestamps. If what you found includes a criminal record for a violent offense or an active restraining order, trust that finding over the impression you formed in conversation.
