I tried hunting through the government website, and it lists a large number of registrars, but none of them seem to offer an easy way to sign up for one. Keep in mind the following things though:

(1) You need to have a business in Nigeria

(2) ccTLDs are subject to local laws, so be careful before basing your brand around a ccTLD name. Case in point: Bitly http://workbench.cadenhead.org/news/3503/bitly-builds-busine...

Very true, without the power of Microsoft it's hard to maintain that domain name... in such a remote place.. I mind as well just give up.

And likewise I searched the government website and none of its accredited registrars offer straight .ng registration

I saw another Nigerian company for which an "exception" had been made. Overall, I think it's risky business right now, especially if you manage to snag a desirable .ng domain. I don't mean this as offensive, but it's not unimaginable in Nigeria that a few greased palms could lead to an "exception" being made for re-assigning your DNS record if you don't have local interests there to back you up.

Official Registry Link for .ng ccTLD : http://www.nira.org.ng

You can use the one Microsoft did: http://www.webdomains.com.ng/

Unfortunately they don't offer .ng on their website, probably still a over-the-counter thing

Hi, I represent Websoft [www.websoft.com.ng], the Registrar for Microsoft's bi.ng. The Buy-Now process of 2nd level .ng domains is on & its not over-the-counter, here is it official link by the registry published in 2010
