PK Domain Restrictions
PK domain restrictions are the naming limits PKNIC applies to every Pakistani address, and checking them before you pay prevents most rejected orders. They cover length, characters, reserved words and patterns that could be mistaken for registry suffixes.
Length. A domain label can be up to 63 characters, not counting the .pk portion, or 67 including it. Long names are rarely wise anyway, because they are hard to share by voice or fit on a shop sign.
Minimum for plain .pk. A name written directly before .pk must be at least four characters, for example abcd.pk or 1234.pk. Three-letter brands and initials cannot be registered as a plain .pk name.
Minimum under suffixes. Under .com.pk and the other third-level suffixes, single-character names are allowed in principle, which is why companies with short acronyms often choose .com.pk.
Hyphens. A name cannot begin with a dash or contain two dashes in a row, a pattern reserved for internationalised domain encodings. A single hyphen between words is fine, though people tend to forget it when repeating an address aloud.
Letters and numbers. Names may use a to z and 0 to 9, and capitals make no difference. Dictionary words are allowed unless they break another rule or sit on PKNIC's reserved list. Together these PK domain restrictions explain nearly every refusal we see.
PKNIC Domain Rules
PKNIC domain rules go beyond length limits to block names that could mislead the public about a website's true address. The registry regards such names as open to masquerading, phishing and electronic fraud, and classes them as a cyber crime and security threat. New registrations and renewals in these classes are not allowed.
The first class covers four-character names directly under .pk that begin with a suffix label such as com, net, org, gov or gop. Names like coms.pk, comm.pk, nets.pk, net2.pk and govs.pk are refused because at a glance they resemble a registry suffix.
The second class dates from August 2013. Since then, no new four-character name before .pk may contain one of those suffix labels anywhere in it.
The third class dates from May 2014. Since then, a new second-level .pk name cannot end with a suffix label such as com, net, org, web, edu, gov or gop. A name like abccom.pk could easily be read as abc.com.pk, exactly the confusion PKNIC wants to prevent.
The current and reserved suffixes covered by these PKNIC domain rules include .com.pk, .net.pk, .org.pk, .fam.pk, .biz.pk, .web.pk, .edu.pk, .gov.pk, the provincial government suffixes and .info.pk. Longer names whose meaning does not collide with the suffix namespace, or with government or education functions, may be approved as exceptions after review.
Restricted PK Domain Names
Restricted PK domain names fall into two kinds: labels that nobody may register, and suffixes that only certain organisations can use. Both catch first-time buyers more often than the length limits.
The first blocked label is www in third-level names. A name such as www.com.pk is not allowed under .com.pk, .net.pk or any other suffix, because browsers and apps treat www specially and a domain built around it could mislead visitors or destabilise .pk DNS. Existing names of this type cannot be renewed.
Reserved suffix labels form the second set. Within the suffixes, the label pk and the names of all second-level suffixes are reserved, so pk.com.pk, net.com.pk, com.com.pk and gov.com.pk cannot be registered by anyone. PKNIC also holds back names such as info.pk and name.pk for its own purposes, so a search may show them as unavailable even when no website uses them.
Category limits make up the third set. The .edu.pk suffix is reserved for recognised educational institutions, while .gov.pk and the provincial suffixes .gop.pk, .gos.pk, .gkp.pk, .gob.pk, .gog.pk and .gok.pk belong to government bodies only.
If you hold an older name that falls under these restricted PK domain names rules, plan a move to a compliant address well before renewal, with permanent redirects so rankings and bookmarks carry across.
PK Domain Documents Required
PK domain documents required depend entirely on the suffix you choose. For the open categories, which are .pk, .com.pk, .net.pk, .org.pk, .biz.pk, .web.pk, .fam.pk and .ac.pk, no paperwork is needed. Accurate contact details, a working email address and a phone number are enough, and the registrant name should be the real person or business that will own the address.
The .edu.pk suffix needs evidence that the applicant is a genuine educational institution. That usually means registration or recognition documents from the relevant authority, such as a board, commission or education department, presented in the institution's name. Private tuition centres and academies without that recognition are better served by .ac.pk, which requires no documents.
Government suffixes need an official request from the department itself. In practice this is a letter on departmental letterhead, signed by an authorised officer, naming the domain requested. IT vendors building a portal may place the order on the department's behalf, but the name must be registered to the government body, not to the contractor.
PKNIC can update its requirements, so our team confirms the current list before submitting any restricted application. Sending clear scans that match the registrant name exactly is the biggest single factor in fast approval. If you are unsure which PK domain documents are required for your organisation, open a support ticket before ordering.
PKNIC Policy
PKNIC policy is the set of registry rules behind every Pakistani name, covering naming limits, registration terms, ownership and the handling of exceptions. PKNIC, the Pakistan Network Information Center, administers the .pk namespace and works through accredited resellers who submit orders on behalf of customers.
Several policy points shape how you manage a name after registration. Pakistani domains are registered for a minimum of two years, not one. The registrant email receives the registry's notices, so it must belong to someone who will read them. Changes of ownership follow a PKNIC procedure, usually involving confirmation from the current registrant, rather than a simple online form.
The policy also allows exceptions. If a name falls into a disallowed class but you believe it is safe and unambiguous, you can request a review. Such requests are sent to the registry at staff@pknic.net.pk, and the decision rests entirely with PKNIC. Have a compliant backup name ready so your launch does not depend on the outcome.
Before ordering, run a quick self-check: enough characters, no suffix label at the start or end, no www or reserved word, no leading or double hyphen, and the right category for your organisation. Then search on our .pk registration page. Our team reviews every application against current PKNIC policy before submission and contacts you if anything looks likely to fail.
