To look someone up online, search their name with a reliable distinguishing detail, open the original sources behind promising results, and corroborate important claims independently. Treat search matches, reverse-image results, and people-search reports as leads—not proof of identity. If the result will determine access to a service or another consequential decision, use an appropriate formal identity-checking process instead of casual web searches.

What “looking someone up on the internet” means

It can mean finding a public professional presence, reconnecting with someone, checking whether an online profile seems credible, or seeing what information about you appears in search results. The right approach depends on the purpose. This guide is about ordinary public-source research and assessing confidence; it is not a way to bypass privacy settings or expose someone’s private details.

How to search for someone by name

  1. Search the name. Add a reliable distinguishing detail, such as a known profession or public affiliation, if the name is common. Google recommends searching your name to see what appears online in its guidance on managing your online reputation. A matching name alone is weak evidence that a result is about the person you mean.
  2. Open the original source. Search snippets and compiled summaries can omit context. Check who published a claim, whether the source is firsthand or repeating someone else, and when it was published. The House of Commons Library explains: “Finding the original source is important because it might come with extra information that can either verify or falsify the image or video.” See its briefing on verifying images and videos.
  3. Compare independent sources. Look for separate sources that point to the same person, and compare names, dates, and relevant details. Several pages repeating one original claim are not several independent confirmations. If the evidence still leaves doubt about whether the result refers to the intended person, say so rather than treating the match as settled.

How to check a photo or profile

Reverse-image search can help show whether the same or a similar image has appeared elsewhere. The FBI recommends researching a person’s photo and profile in its specific guidance on romance scams. An earlier appearance may point to reused or stolen imagery, but it does not establish who operates the profile. An authentic image can also be presented with a false explanation; the House of Commons Library’s verification briefing stresses the importance of checking the original context.

What people-search sites can—and cannot—tell you

In the United States, the FTC describes people-search sites as a type of data broker. They may compile information from other brokers, public social profiles, and government public records. Reports can include sensitive or outdated details such as addresses, relatives, work or education history, and court records. Treat a report as a lead: verify any important claim against its original source and date, and do not spread sensitive personal details that are unnecessary to your purpose. The FTC explains how these sites work in its consumer guidance.

When a web search is not an identity check

A casual search is not a substitute for identity checking when a decision affects access, benefits, or a regulated service. UK Government GPG 45 is a structured framework for identity-checking contexts. It considers the strength and validity of evidence, whether an identity has existed over time, fraud risk, and whether the identity belongs to the claimant. It says one attribute is not usually enough to distinguish a person and that methods can be combined to reach a confidence level suited to the need. This is UK government guidance for those contexts, not a universal rule for personal searches.

If you are checking an online dating contact

Searching a profile cannot guarantee that a stranger is who they claim to be. For romance-scam prevention, the FBI advises being careful about what you make public, researching a person’s photo and profile for reuse, and proceeding slowly. Be alert to requests for financial information or repeated excuses to avoid meeting, and never send money to someone you know only online or by phone. These are precautions, not a way to authenticate someone conclusively; see the FBI’s romance-scam guidance.

How to manage information about yourself

Review search results and unwanted pages

Search your name and identify who controls any page you want changed. In the UK, the ICO says you can ask a search provider to consider delisting a name-search result that significantly affects your privacy rights. The provider weighs the request, including public interest. Delisting does not erase the original page, so full removal may require contacting its publisher. The ICO’s guidance on internet search results is under review following legislative changes; check the current local process before relying on it for legal instructions.

Consider people-search opt-outs carefully

The FTC says you can submit opt-out requests to data-broker sites one at a time or use a paid service. Opting out does not remove information from public records; information in a related person’s report may still appear, and changed records can cause information to return. Before paying a service, check how many sites it covers, whether it reports completed removals, how often it scans, and how it handles reappearing or newly found information. The FTC sets out these limits and comparison questions in its people-search-site guidance.
