What Network is 081 in South Africa? Understanding Mobile Number Prefixes (2025)

Business / July 19, 2025 / Melly Brown

Have you received a call or seen a number starting with 081 in South Africa and wondered which mobile network it belongs to? With the evolution of South Africa’s telecommunications sector and the common practice of number portability, identifying the exact network from a mobile prefix can sometimes be confusing.

This detailed guide will clarify which mobile providers in South Africa primarily use the 081 number range, explain the impact of number portability, and provide a comprehensive overview of South Africa’s mobile numbering plan in 2025.

South Africa’s Mobile Numbering Plan: An Overview

In South Africa, the Independent Communications Authority of South Africa (ICASA) is the regulatory body responsible for allocating mobile number ranges to various licensed telecommunications providers. Historically, major mobile network operators (MNOs) like Vodacom, MTN, and Cell C were assigned unique prefixes (e.g., 082, 083, 084).

As the mobile market expanded and new players emerged, new number ranges, including portions of the “08” series and the “06” series, were introduced to meet the growing demand for mobile connectivity.

The Impact of Number Portability A crucial aspect to understand is number portability. This service allows mobile subscribers to keep their existing phone number even when they switch their service from one network provider to another (e.g., from Telkom Mobile to MTN). Therefore, while an “081” number was originally allocated to a specific network, it could now be actively used on a different network due to a porting request. For more information on how number portability works in South Africa, you can visit the official ICASA website.

What Network Primarily Uses the 081 Prefix?

The 081 prefix in South Africa is most strongly associated with Telkom Mobile (formerly 8ta), which was allocated a significant portion of this range when it launched its mobile services. However, other networks, including Rain and even some sub-ranges of MTN and Vodacom, also utilize the 081 prefix.

Here’s a breakdown of the primary network associations for sub-ranges within the 081 prefix, based on original ICASA allocations:

Mobile Number Prefix	Primary Associated Network (Original Allocation)
0810	MTN
0811 – 0815	Telkom Mobile
0816	Rain (previously WBS Mobile/iBurst for some services)
0817	Telkom Mobile
0818	Vodacom
0819	Telkom Mobile

Important Note: As explained, due to number portability, a number starting with 081 (e.g., 081 234 5678) might currently be active on any of South Africa’s major mobile networks, including Vodacom, MTN, Cell C, or Telkom Mobile, even if its original allocation was different.

Why Knowing the Original 081 Network Can Still Be Helpful

Even with number portability, understanding the original allocation of the 081 range can offer benefits:

Historical Context: It provides insight into the allocation patterns and growth of South Africa’s mobile industry.
Likely Origin: In the absence of other information, the original allocation is the most probable network where the number originated.
Network-Specific Offers (Less Common): While rare with modern bundled plans, some older promotions might have been tied to calls within specific original networks.
Curiosity: For many, it’s simply a quick way to identify the network that initially issued a particular number.

How to Accurately Confirm a Mobile Number’s Current Network

If you need to definitively identify the current network of any South African mobile number, particularly for ported numbers, these methods are the most reliable:

Directly Ask the Subscriber: The simplest and most accurate method is to ask the person who owns the number.
Network Confirmation Services (USSD): Some mobile networks offer USSD (Unstructured Supplementary Service Data) codes or SMS services that allow you to check the current network of a number. The availability and cost of these services vary by provider.
- Always check with your specific mobile network operator’s customer service or website for their latest USSD options.
Online Network Lookup Tools (Use with Caution): A few third-party websites or applications claim to offer network lookup services. While some may provide accurate information for ported numbers, their reliability and privacy practices can vary. Always exercise caution when using such services.

Other Key Mobile Number Prefixes in South Africa

Beyond the 081 range, South Africa uses several other prominent mobile number prefixes:

060 – 069: This broader range is used by various mobile providers, including MTN, Vodacom, Cell C, Telkom Mobile, and Rain, introduced more recently to expand capacity.
071: Primarily MTN and Vodacom.
072, 076, 079: Predominantly Vodacom.
073, 078: Predominantly MTN.
074: Predominantly Cell C.
082: Historically and predominantly Vodacom.
083: Historically and predominantly MTN.
084: Historically and predominantly Cell C.

Conclusion: Understanding South Africa’s Mobile Connectivity

In summary, while the 081 prefix in South Africa is most strongly associated with Telkom Mobile based on its initial allocation, the widespread use of number portability means that an 081 number could be currently active on any major mobile network, including Rain, Vodacom, MTN, or Cell C.

Understanding these number ranges, along with the power of number portability, provides valuable insight into South Africa’s dynamic and competitive mobile telecommunications environment. For precise identification, directly asking the number holder or using official network tools remains the most reliable approach. Stay informed and connected!
