Every domain registrar? is slightly different, but the important thing is if they would support your TLD?. Some TLDs like .ws domains can only be acquired through one registrar where almost all registrars will support .com domains. No matter what, you would need to provide for public accessible information. This is why an email address, mailing address, and voicemail number is part of your requisites. Some registrars will give you private WHOIS information, but this isn’t always available. However, once you find your registrar, I will recommend that you consider using them for all of your registrar needs. If you are curious, my register is Name.Com. As with the finding your host, using my referral link will be preferable.
