Tucows is a wholesaler of domain names and other Internet services to ISPs and web hosting companies worldwide. We do not sell domain names directly to consumers.
That is most likely because some registrars are open just for the purpose of selling to resellers. Doing so makes their resellers happy because then the resellers wont have to worry about competing against the wholesaler on pricing. And no, Tucows does not sell to godaddy and register.com. Why should they? godaddy and register.com are their own ICANN accredited registrar. A registrar will never resell domains through another registrar. That is just defeating the purpose of owning a registrar. heh.
Let me see if I can break this down for you in simpler terms:
At the very top of the tree we have a company called VERISIGN. They are known as the REGISTRY for gTLDs. You cannot deal with them directly unless you are a registrar. The registry sets what the wholesale pricing will be each year for the registrars. An increase at the registry level usually means a price increase at the registrar level for customers.
Under that 1 registry are REGISTRARS. These registrars are all listed (HERE:
ICANN | ICANN-Accredited Registrars). That list of registrars includes godaddy, register.com, enom, namecheap, etc. (They are ALL there). When a person like you goes to Godaddy.com for example to register a domain, you check to see if your name is available. If it is, then you pay for it. Then, the REGISTRAR communicates with the REGISTRY to register the domain on your behalf. There is no way of bypassing the registrar. You HAVE to go through a registrar to register your domains since they are the ones who communicate with the REGISTRY.
Now, UNDER the REGISTRAR are RESELLERS. RESELLERS are people who provide domain registrations through a registrar but usually get wholesale pricing through the registrar. People usually become resellers because they cannot afford the MASSIVE costs of becomming an ICANN accredited registrar. So they become a reseller for the registrar instead.
As for ICANN, these are the people who police the system. They ensure that registrars are being fair to the customers they sell to. If a registrar is accredited by ICANN, then that is a VERY good thing because it means the registrar will follow policies set by ICANN to maintain fairness for their customers.
I hope this helps clear things up for you.
