Investigator Use
NumLookup is a free international phone number lookup service that provides carrier identification, geographic location, line type classification (mobile, landline, VoIP), and basic number validation for any phone number. It supports numbers from most countries worldwide.
For OSINT investigators, NumLookup provides immediate basic enrichment for any phone number encountered during investigation. The carrier identification reveals the mobile network operator or service provider, which is useful for understanding how to route legal process for subscriber records and what MVNO (Mobile Virtual Network Operator) arrangements might affect data availability.
Line type classification — distinguishing mobile, landline, and VoIP numbers — has immediate investigative significance. VoIP numbers are commonly used for fraud, scam calls, and by subjects avoiding traditional telecom identification because they are easier to obtain anonymously and harder to trace to physical addresses than traditional numbers. A VoIP classification flag for a suspect number changes the investigation approach significantly.
Geographic number verification confirms that a phone number is actually from the claimed location — a US phone number on a scam call claiming to be from a local organization can be verified as to whether the area code and number format are consistent with the claimed location.
For phone number validation in large datasets (fraud investigation, database analysis), NumLookup's free tier provides sufficient volume for initial triage — separating valid numbers from invalid ones before investing deeper investigation resources.
NumLookup's international coverage makes it appropriate for investigations involving phone numbers from non-US countries, where other people-search tools have no data.
Limitations: NumLookup provides carrier and line type data but not subscriber identity — it does not identify who owns a specific phone number, only the carrier and basic technical characteristics. For subscriber information, carrier legal process is required.
Document queried phone numbers, carrier identified, line type, geographic location, and query timestamps for case records.

FamilyTreeNow is a free U.S.-based people search and genealogy tool that aggregates publicly available records into searchable profiles. It helps users find individuals by name, view current and previous addresses, identify possible relatives, discover aliases, and explore historical household connections. Investigators, journalists, and OSINT professionals often use FamilyTreeNow during the early stages of an investigation to generate leads, verify identities, map family relationships, trace address history, and uncover potential associates. Since the platform compiles information from public records, it serves as a starting point for research rather than a definitive source. Any findings should be verified through official records or additional trusted sources before being relied upon for investigative or legal purposes.
