About LookupTools

LookupTools is a free online resource providing dozens of lookup and query tools for everyday internet users, developers, investigators, and curious minds. Our goal is to make information that was once hard to find accessible to everyone, with no registration required.

What We Offer

Our collection of tools covers a wide range of lookup needs. IP lookup tools help you identify the geographic location, ISP, and other details about any IP address. Phone number lookup tools can help identify unknown callers and associated information. Domain lookup tools provide WHOIS data and registration details for any domain name.

We also offer specialized tools for developers and technical users, including ASN lookup, MAC address vendor lookup, IBAN validation, VIN decoding, IMEI information retrieval, and GPS coordinate conversion. Each tool is designed to be fast, accurate, and easy to use.

Privacy Commitment

We take privacy seriously. Where possible, our tools operate entirely in your browser — no data is sent to our servers. For lookups that require external queries, we use minimal data and never store query results. We don't track, log, or sell any user data.

When you use our IP lookup tool, for example, the lookup is performed locally using browser-based geolocation databases. For tools requiring WHOIS queries or similar external data, we forward the request without personally identifiable information.

Our Mission

We believe information should be free and accessible. Whether you're a developer debugging network issues, a business researching potential partners, or just someone trying to identify an unknown phone number, our tools should be available when you need them — not behind a paywall or registration form.

We continuously add new tools and improve existing ones based on user feedback. If there's a lookup tool you need that we don't currently offer, please let us know. We're always looking to expand our coverage.
