All domain applications for the pk domain names must agree to the registration policy agreement available on the PKNIC website. Following are the rules you should keep in mind while registering your pk domain.
The .pk domain name length should not exceed 63 characters & 67 characters with “.pk” or “.com.pk” suffix.
.pk domains cannot start with a hyphen or dash “-“, and there cannot be two consecutive hyphens “–” within the name. Just like in international domains (Global top-level domains – gTLDs), these are reserved.
You can register .pk Domain names with dictionary words as long as they do not violate the PKNIC registration policy.
The domain name being registered should not present in the list of blocked or /and reserved names.
You can register pk domains without assigning any name servers.
Second Level PK Domains
The minimum length for pk domains of 2nd level (ending with .pk only example your-name.pk) is four characters. i.e., your.pk or 4321.pk. (786.pk is not a valid domain and cannot be registered till now. It will appear as available on PKNIC domain availability search, but it can’t be registered)
The four characters’ 2nd level pk domain name must not start with PKNIC second level sub-domains (used in the third level). i.e., com, net, org, biz, web, fam, info, and the PKNIC subdomains used for the government, for example, gov, GOP, GPK, GOS, GOK, GOG, and GOB. Example: The following domains are not valid: Nets.pk, Comm.pk The following domains are valid: Netsip.pk, snet.pk, Commax.pk
Third Level COM.PK, Etc Domains
For the third level PK domains, one can register domains as short as one character long.
