Associated Domain Finder Examples · Example 6 of 11 in One Association Type

Same Normalized Registrant Phone

GEThttps://api.deepinfo.com/v1/discovery/associated-domain-finder

The same number, normalized (16503198930): 19 domains instead of 2, because most WHOIS records write it as +1.6503198930.

Param: association ordering domain
Value: whois_registrant_phone_normalized punycode cloudflare.co.at

association=whois_registrant_phone_normalized compares the normalized number (domain.whois_normalized.registrant.phone, digits only: 16503198930), so the way a WHOIS record writes it does not matter.

The API found 19 domains instead of 2: +1.6503198930 and +1 650 3198930 now match +16503198930 as well. Most of them are Cloudflare’s own registrations; a few .us domains registered through Cloudflare’s registrar give the same number. This example adds ordering=punycode, so the records shown are the first three by name on every call: cloudflare-email.com, cloudflare-email.net and cloudflare.ai. The normalized contact of cloudflare.ai names no organization, so this page redacts it (REDACTED FOR PRIVACY); its WHOIS record shows the number as +1.6503198930.

In the response, look at result_count, results[].domain.whois.registrant.phone and results[].domain.whois_normalized.registrant.phone.
