A Pakistan network code is the four-digit prefix at the start of a mobile number, such as 0321 or 0345. The Pakistan Telecommunication Authority (PTA) assigns each prefix block to a specific operator, so the digits right after the leading 0 tell you which network originally issued that number. That’s useful, but it isn’t the full picture. Thanks to Mobile Number Portability, a person keeps the same number even after switching operators, so the prefix shows where a number came from rather than always confirming where it is today.

What Is a Mobile Network Code in Pakistan?
A mobile network code, also called a SIM prefix, is the first four digits of a Pakistani mobile number. Take a number like 0321-XXXXXXX. The “0321” part is the prefix. The remaining seven digits are the subscriber’s own line, unique to that one SIM.
PTA hands out these prefixes in blocks, not one at a time, so an entire range like 0320 to 0329 gets assigned to a single operator at once. That’s why people search “which network code” so often. Someone gets a call from an unfamiliar number, spots a saved number in an old phone, or wants to confirm a network before buying a new SIM, and the fastest way to answer that is by checking the prefix.
A prefix is not the same thing as a complete phone number. It doesn’t identify one specific person or SIM on its own. What it tells you is which operator the number belongs to, based on how PTA originally divided up the number ranges.
Pakistan Mobile Network Codes by Operator
Jazz Network Codes
Jazz holds two separate prefix blocks, and the difference comes down to history rather than anything technical. Numbers starting with 030x were issued under Mobilink from the start. Numbers starting with 032x were originally Warid Telecom prefixes, and they moved to Jazz after Mobilink and Warid merged and adopted the single Jazz brand in 2017.
Several 032x codes already have their own detailed guide on PakBiz, including 0321, 0324, 0328, 0323, and 0329. Each guide explains the specific prefix’s history and what it means for calls made to or from that number today.
Zong Network Codes
Zong’s original allocation runs from 0310 to 0319, and 0318 falls inside that range. As demand for new numbers grew, PTA gave Zong a second, newer block starting with 037, which includes 0371.
Both blocks belong to the same network and offer identical service. For a closer look at either one, see the 0318 and 0371 guides linked in the table above, which explain why the newer 037x prefixes exist.
Ufone Network Codes
Ufone’s prefixes fall in the 033x range. This block also covers Onic, a newer digital-only brand that operates as part of Ufone and uses the 0339 prefix specifically. Detailed guides for individual Ufone prefixes are on the way and will appear here once published.
Telenor Network Codes
Telenor’s numbers start with 034x. Telenor is part of the PTCL Group and runs its own separate prefix block, distinct from the other three operators. As with Ufone, dedicated prefix guides for 034x numbers will be added to this page as they go live.
How to Identify a Network From a Mobile Number
Checking a number’s original network only takes a few steps.
- Look at the first four digits of the mobile number, before the dash.
- Match those digits, the prefix, against the table above or the operator sections on this page.
- If a detailed guide exists for that exact prefix, open it for the complete history and any extra detail.
- Keep Mobile Number Portability in mind. The prefix confirms where the number was first issued, not necessarily who provides service on it right now.
For example, a number written as 0321-XXXXXXX carries the 0321 prefix, which was assigned to Jazz. That tells you the number’s original network. Whether it’s still on Jazz today depends on whether the owner has ported it elsewhere, which the prefix alone doesn’t show.
Can a Mobile Number Change Its Network?
Yes. Pakistan allows this through Mobile Number Portability, or MNP, a service PTA introduced under the Mobile Number Portability Regulations, 2005, with the system going live in March 2007. Pakistan was the first country in South Asia to offer it.
MNP lets a subscriber move from one operator to another while keeping the exact same number. Porting is handled through the Pakistan MNP Database, a system jointly run by the operators themselves, and it works by transferring the number’s service to a new SIM on the new network rather than issuing a new number.
This is exactly why a prefix should be read as a starting point, not a final answer. A 0321 number was issued by Jazz, but if that subscriber ported it to another operator afterward, the number still starts with 0321 while the actual service now runs on a different network. Don’t assume every number sharing a prefix is currently on the same operator.
How to Check the Current Network of a Mobile Number
The prefix tells you where a number was first issued. It doesn’t confirm where it is today once MNP is involved. If you’re checking your own number, your operator’s official customer support confirms your current network status directly.
There isn’t a confirmed, PTA-run public tool that lets anyone look up which operator currently serves someone else’s number. Be cautious of third-party websites that claim to offer this, since PakBiz hasn’t verified their accuracy or how they handle the numbers submitted to them. The safest way to confirm a number that isn’t yours is to ask the person directly or rely on the operator’s own official channels.
Mobile Number Formats in Pakistan
Pakistani mobile numbers appear in two common formats. Domestically, they’re written with a leading zero, like 0321-XXXXXXX. For international calls, the leading 0 is dropped and replaced with the country code, so the same number becomes +92 321 XXXXXXX.
Both formats point to the same number. The only difference is whether you’re dialling from inside Pakistan or from abroad.
Important Note About Network Codes
A mobile prefix is a reliable way to identify which operator a number was originally issued to, and that’s genuinely useful information. It shouldn’t be treated as proof of the current network, though, since Mobile Number Portability allows the actual service behind any number to change while the digits stay the same.
FAQs
What is a network code in Pakistan?
A network code is the four-digit prefix at the start of a Pakistani mobile number, such as 0321 or 0345. PTA assigns each prefix block to a specific operator, so it identifies which network originally issued the number.
How do I identify a mobile network from a Pakistani number?
Check the first four digits of the number and match them against a verified network code table, like the one on this page. If a detailed guide exists for that exact prefix, it will confirm the history behind it.
What do 03xx numbers mean in Pakistan?
Every mobile number in Pakistan starts with 03, followed by two more digits that complete the four-digit prefix. Together, those four digits show which operator the number was allocated to by PTA.
Can a mobile number change networks in Pakistan?
Yes, through Mobile Number Portability. A subscriber switches to a different operator and keeps their existing number, so the number itself doesn’t change even though the network behind it does.
Does a SIM prefix always show the current network?
No. It shows the network the number was originally issued to. If the owner has ported it to another operator through MNP, the prefix stays the same while the actual service provider changes.
Which networks operate mobile services in Pakistan?
Pakistan’s mobile market is served by Jazz, Zong, Ufone, and Telenor, along with smaller operators such as SCOM in Azad Jammu and Kashmir and Gilgit-Baltistan, and Onic, a digital brand under Ufone.
How do I check a specific Pakistan network code?
Search for the exact prefix on PakBiz. Codes with a published guide, listed in the table above, give you the full detail. For prefixes not yet covered, the operator breakdown on this page still shows which block they fall into.
