Yes for full functionality. | | Cookies | Mainly Google Analytics/Google advertising cookies, plus a ASP.NET session cookie. | | Ownership | A LinkedIn profile lists Robert Scott as CEO and Founder, based in Arizona. | | Use in Reporting | Useful for corroborating the type, carrier and approximate geographic association of a phone number. | ### What does Phone Validator do? Phone Validator checks whether a telephone number appears valid and provides information such as line type, current phone company/service provider, approx. city/state or regional location based on the number’s area code and prefix, whether the number is identified as fake or valid, and porting information to help determine the current line type. The service also states that it supports numbers worldwide, including more than 250 countries. **The lowdown:** It’s a phone-number verification and enrichment tool. ### How to Use: **1. Enter the telephone number into Phone Validator. For numbers outside the US and Canada, the site recommends including the international + prefix.** **2. Review the returned information, such as line type, carrier, location and fake/invalid status.** **3. Cross-reference the result with independent sources and record the date of the lookup if using it in an investigation.** ### Cost * [ ] Free * [x] Partially Free * [ ] Paid Individual web validation is free while API/batch/dashboard services are paid. ## Data Processing ### Account Required: * [x] Yes * [x] No No for the basic free web lookup but an account is required for API/paid services. ### Cookies: The site uses Google Analytics cookies (\_ga, *ga*\*, \_gid) for website usage and session measurement, a Google advertising/conversion cookie (\_gcl\_au), and an ASP.NET session cookie (ASP.NET\_SessionId) for maintaining the user's website session. ### Use in Reporting Phone Validator can be used to: * Establish whether a telephone number appears valid or potentially fake. * Determine whether a number is a mobile, landline, VOIP or toll-free number. * Identify the current service provider/carrier where available. * Establish an approximate geographic association from the number's area code and prefix. * Check whether number portability may have changed the current line type. * Corroborate telephone information obtained from other open sources. * Generate further investigative leads for researching a phone number. * Support technical verification of a phone number without claiming that it identifies a particular person. The platform is cited in [a peer-reviewed academic study ](https://pmc.ncbi.nlm.nih.gov/articles/PMC10504660/)that specifically lists Phone Validator among OSINT tools for phone-number research. The researchers tested it as part of an OSINT survey and reported that it could provide information such as the number type, operator and geographic area. In their testing, it correctly matched the US number they tested. | **Capabilities** | **Limitations** | | ---------------------------------------------- | --------------------------------------------------------------------------------------------------- | | Can identify potentially fake/invalid numbers. | Does not establish who owns or controls a number. | | Supports worldwide phone-number validation. | Carrier information can change, particularly following number porting. | | Identifies telephone line type. | Location is based on numbering information, not live device location. | | Provides carrier/service-provider information. | A number being classified as valid does not prove that it is currently used by a particular person. | | Provides approximate geographic information. |


| ### Summary Phone Validator is a useful phone-number verification and enrichment tool for establishing line type, carrier, approximate geographic association, and potential validity. It therefore fits particularly well in the verification and analysis stages of an OSINT investigation, but it should not be used alone to attribute a phone number to an individual. ### Ownership A LinkedIn profile lists [Robert Scott](https://www.linkedin.com/in/phonevalidator/) as CEO and Founder in Arizona. WHOIS data is concealed. ### Ethical Considerations * Treat phone-number results as supporting evidence, not proof of identity or ownership. * Do not assume that the approximate location of a number represents the current physical location of its user. * Record the date of the lookup, as carrier and numbering information can change. * Be aware that Phone Validator's terms state that the service is intended for business and commercial purposes. * Do not use the service's results for prohibited purposes such as determining eligibility for credit, insurance, employment or housing; its terms expressly restrict such uses. * Cross-check important findings against independent and authoritative sources. ### Related Tools: * NumVerify * Truecaller * [BeenVerified](/osint-tools/beenverified.md) * [192.com](/osint-tools/192.com.md) #### Sources
