Many people use a separate phone number on their Whois records than they use for their personal needs. They don’t want their home or cell phone ringing at all hours, or they want to know specifically when the phone is ringing for a possible domain inquiry. I know a few people who use a toll-free number for their Whois records, and I don’t think this is a great idea.
During the last couple of years, it seems that there has been a massive increase in the number of spam robocalls that are being made. I believe some spammers are targeting phone numbers on Whois records, especially on new domain name registrations. My belief stems from the fact that I get a ton of spam text messages after I register a domain name, and I also receive quite a bit of junk mail addressed to new domain registrations. I think spammers assume new domain names mean new businesses are starting, and they believe their plethora of loans, SEO help, and other website offerings would be well targeted.
There are a number of toll free phone number services that are easy to use and setup. Most if not all of these services charge their users for the number of minutes used per month. Although most robocalls seem to hang up before the voicemail prompt, I have received a few recorded voicemail messages that are clearly done by robocallers. As annoying as it is for me to check my cell phone messages, I would be perturbed if I were paying for a robospammer to leave me a voice mail via my toll free service.
I already received three robocalls this morning. Sometimes I receive more and sometimes I receive less calls. It’s annoying, but fairly harmless. If these calls were being made to a toll free number and I had to pay each time, it would get me really upset. This is something to consider when setting up a separate phone number for your Whois records.
