I've been waiting for this for long, so which registry can we use to get .ng?
(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...
And likewise I searched the government website and none of its accredited registrars offer straight .ng registration

So far, The domains listed below have been registered by Websoft:
1)3m.ng 2)leadership.ng 3)google.ng 4)gmail.ng 5)youtube.ng 6)honeywell.ng 7)googli.ng 8)bi.ng
