When you buy a domain name, your contact information needs to be submitted by your registrar to the WHOIS directory. Since the WHOIS directory is publicly accessible,  personal information like your name, phone number, address and email id become freely available to spammers, telemarketers and other kinds of offensive characters.

You can prevent this from happening by opting for private domain registration. With private registration, alternate contact information will be used to register your domain thereby protecting you from all kind of threats. Some registrars also provide an email address that will filter messages for spam before forwarding them to your preferred email account.

Private registration also gives you the choice to decide on the kind of information you wish to publicize about your business.

It’s therefore a good idea to include private registration when you purchase a domain. Registrars might charge a small amount for this add-on service. However, this would amount to nothing when compared to the kind of security you would be getting in return.
