Applications for these domains must conform to the PKNIC registration policy agreement in addition to the requirements given below.

1. The maximum domain name length is 63 characters (excluding the suffix .pk, .com.pk, etc). Total domain length can not exceed 70.
2. For second level .PK domains, the minimum length for the domain name, exclusive of the .pk portion is four characters (e.g. 1234.pk). A four character name before .pk can not start with one of the PKNIC second level sub-domains (e.g. com, net, org, gov, gop, etc.). For example the following domain names are not acceptable:  (coms.pk, comm.pk, nets.pk, net2.pk, govs.pk, a-ac.pk, etc). The complete list of the .PK current and reserved sub-domains includes but is not limited to .COM.PK, .NET.PK, .ORG.PK, .FAM.PK, .BIZ.PK, .WEB.PK, .EDU.PK, .GOV.PK, .GOB.PK, .GOG.PK, .GKP.PK, .GOP.PK, .GOS.PK, .GOK.PK, .INFO.PK. For the second-level subdomains less than three characters, a dash (-) prefix is added for the inclusion check purpose.
3. To help minimize website phishing attacks, the following restrictions are placed:
   • Any new domain registration, since August 2013, with a four character name before .pk can not contain one of the PKNIC second level sub-domains (e.g. com, net, org, gov, gop, -ac, etc.)
   • Any new second level domain registration, since May 2014, can not end with one of the PKNIC second level sub-domains (e.g. com, net, edu, org, biz, web, -ac, fam, gov, gop, gos, etc.) Exceptions can be made for longer names who’s meaning are not easily confused with second level sub-domain space.
4. For third level .COM.PK, etc domains, the minimum domain name of one character are allowed (e.g. a.com.pk). The label ‘pk’, ‘www’ and all the second level suffix names are reserved for these domain types (e.g. can not register pk.com.pk, net.com.pk, www.net.pk, com.com.pk, gov.com.pk, etc).
5. A domain name can not begin with a dash “-“, and can not have two consecutive dashes “–“in it. These are reserved for IDN encodings
