Most big hosting companies and domain registrars will not only tell you a domain any less than three letters is invalid, but they probably won’t support whichever obscure ccTLD (Country Code Top Level Domain, e.g. .ca for Canada) you feel like owning. There’s no real reason for this, other than that most companies are stupid and don’t know what the hell they’re doing. Especially when it comes to technological stuff like this; the CEO of GoDaddy probably doesn’t have more than a vague idea about how the internet really works. Oh well, more power to the people.

And by “the people” I mean the people at iwantmyname.com. Not only is their service great, with a nice clean interface and a whole six pages of TLDs to choose from, but they accept ANY valid domain, including those with only two characters at the second level.

It’s a great service, and I’ve used them to buy all two of my two letter domains. I even started a little URL shortening service of my own, called zi.gs, just for fun. I took it down a while ago after it became boring and tiresome to provide support for.

Anyways, there you have it. Easy two character domains, supporting lots and lots of TLDs.
