Is it possible to search WHOIS data by parameters such as: registrant name, registrant email, registrant zip/postal code?

  • Not really. Domaintools.com does give you some of this for a price. Not worth the price though. – closetnoc Apr 18 '16 at 21:15
  • Most Registrar WHOIS searches are limited to just the domain name to prevent marketing and spamming, as covered under ICANN's Uses of WHOIS. There are "research"/database sites whom aren't registrars themselves and therefore are not bound by these same terms, such as DomainTools. These provide domain name and registration searches by more criteria, usually on a subscription basis to find out more details. – dan Apr 19 '16 at 2:56
  • As a matter of curiosity, why are you asking? We have gotten this question a few times and I simply do not understand why. Can you fill me into why you are interested in being able to search this way?? – closetnoc Apr 19 '16 at 3:12

No. If you search the Network Solutions WhoIs database, you only get 2 search options:

  • By Domain Name
  • By IP Address

If you search for a zip code like: "90210", it will try to lookup "90210.com". It won't search for all domains in the 90210 (Beverly Hills, CA) zip code.
