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