1 and 2 digit numerical domain names will soon be available for registration soon in .GP. One hundred domain names are available from 00.gp to 99.gp and ten domain names from 0.gp to 9.gp.
More information is available on registering .GP domain names from www.nic.gp or by contacting them by email at register@ntgroup.gp for more information.
There is also an announcement on the NIC.GP website in Chinese and English saying:
Dear chinese visitor, please do not register if you know that you will never pay for registration. All requests concerning domain name protected by international laws will be rejected if not coming from owner of the trademark.
One can only presume there have been some problems with Chinese residents registering .GP domain names.
