Introduction
In Pakistan, mobile network operators use specific SIM codes, also known as network prefixes, to identify their networks. These prefixes are the first four digits of a mobile number and are essential for users to recognize which network a number belongs to, such as Jazz, Zong, Ufone, or Telenor. This information is valuable for cost-effective communication, customer service interactions, and targeted marketing campaigns. As of May 2025, this article provides a comprehensive list of SIM codes for Pakistan’s major mobile networks, along with an explanation of their significance.
What Are SIM Codes?
SIM codes are the initial digits of a mobile number that indicate the network provider. For example:
- A number starting with 0300 is associated with Jazz.
- A number starting with 0333 is associated with Ufone.
These codes are assigned by telecommunication authorities in Pakistan and are unique to each network. They help users and businesses identify the network for various purposes, such as determining call or SMS rates (same-network communication is often cheaper) or ensuring accurate service requests.

Network Details
- Jazz: Jazz, formerly Mobilink, is Pakistan’s largest mobile network operator. It merged with Warid in 2017, incorporating Warid’s 032x prefixes (0321–0329) alongside its original 030x prefixes (0300–0309). This makes Jazz’s range of codes the most extensive among the major networks. Visit Jazz’s official site for more details.
- Zong: Zong, known for its robust 4G services, uses the 031x prefix (0310–0319). Some sources mention a 0370 prefix, but it is not widely confirmed for 2025 usage. Zong is a popular choice for internet-focused users. Check Zong’s website for updates.
- Ufone: Ufone, a key player in Pakistan’s telecom market, uses the 033x prefix (0330–0339). The 0339 code includes ONIC, a digital sub-brand of Ufone. Ufone is also noted for its advancements in 5G technology. See Ufone’s site for more information.
- Telenor: Telenor, recognized for its innovative services and wide coverage, uses the 034x prefix (0340–0349). It is a reliable choice for both urban and rural users. Visit Telenor’s website for the latest offerings.
Why SIM Codes Matter
Understanding SIM codes is important for several reasons:
- Cost Management: Calls and messages within the same network are often cheaper, so knowing the network helps users save money.
- Customer Service: When contacting support, identifying the network ensures you reach the correct provider.
- Marketing and Outreach: Businesses use SIM codes to target specific network users for promotions or campaigns.
- Network Identification: For new or unfamiliar numbers, the prefix quickly indicates the network, aiding communication decisions.
Additional Context
- Warid’s Integration: Warid, once a standalone network, merged with Jazz in 2017. Its 032x prefixes (0321–0329) are now part of Jazz’s network, but some users still associate these codes with Warid. For historical context, see Warid Pakistan on Wikipedia.
- Other Codes: Some sources mention additional codes, such as 0370 for Zong or 0339 for ONIC (part of Ufone). However, the primary prefixes listed above cover the vast majority of active numbers in 2025.
- Service Codes: Beyond network prefixes, networks use USSD codes (e.g., *123# for balance checks) for services. While not the focus of this article, these are distinct from SIM codes and are used for account management. For example, Jazz’s balance save code is *275#.
Staying Updated
The SIM codes listed are accurate as of May 2025, based on multiple sources. However, telecom providers may introduce new prefixes, retire old ones, or undergo mergers that affect these codes. To ensure you have the latest information:
- Visit the official websites of Jazz, Zong, Ufone, and Telenor.
- Check reliable telecom blogs like Mobile Packages for updates.
- Contact customer service for specific inquiries about new or unusual prefixes.
