Frequently asked questions
OneLookup scans billions of records across dozens of specialized data providers. When you enter a phone number, an email, or upload a photo, our system cross-references multiple sources and compiles the results into a single, comprehensive report.
You can look up someone with a phone number, an email address, or a photo of their face. Pick the one you have — each surfaces different angles on the same person.
Yes. Your lookups are completely confidential. The person you look up will not be notified, and your lookup history is only visible to you in your account.
Our system pulls from 58 data providers that are continuously updated. While no data source is perfect, OneLookup cross-references multiple providers to maximize accuracy and surface details that a single source would miss.
OneLookup aggregates information from a wide range of specialized data providers, proprietary databases, social networks, directories, and other sources — many of which are not accessible through standard search engines.
Absolutely. You can cancel at any time with one click from your account settings — no phone calls or emails needed. Your access continues until the end of your current billing period.
Most lookups complete within seconds. Photo lookups may take up to 2–3 minutes as our system scans millions of images across the web.
OneLookup is not a consumer reporting agency as defined by the FCRA. You may not use our service for employment screening, tenant screening, credit decisions, or any purpose covered by the FCRA. Do not use OneLookup to stalk, harass, or monitor anyone.
Upload a photo of someone on the photo lookup page — we match the face against millions of public profiles, news, and images across the web. Most lookups complete in 30 seconds to 2 minutes. Your upload isn’t shared with third parties beyond the matching process.
Yes. OneLookup supports international phone lookups. Simply enter the full phone number including the country code in the search bar. Coverage and depth of results may vary by region.
Free lookup tools rely on limited, outdated sources. OneLookup invests in deep data acquisition across 58 specialized providers to deliver results that free tools simply can't access — including social profiles, addresses, employment history, and more.
