Most South Africans recognise cellphone numbers like 082, 072, or 062 instantly and often assume they tell you exactly which mobile network a person is using. That assumption used to be mostly correct, but over time the meaning of these prefixes has changed.
Understanding what these number prefixes actually represent — and what they no longer guarantee — helps explain why a number that looks like it belongs to one network may in reality be on another.
How South African Cellphone Numbers Are Structured
South African cellphone numbers are ten digits long when dialled locally and always start with a 0. The first three digits — such as 082, 072, 083, or 062 — are known as the mobile number prefix.
These prefixes form part of South Africa’s national numbering plan and were originally allocated to mobile operators in specific blocks. At the time, the prefix clearly indicated which network the number belonged to.
Original Network Allocations
When mobile phones first became widespread in South Africa, prefixes were tightly linked to specific networks. The most well-known examples include:
• 082 — originally allocated to Vodacom
• 083 — originally allocated to MTN
• 084 — originally allocated to Cell C
• 081 — originally allocated to Telkom
As subscriber numbers grew, additional ranges were introduced:
• 072 and 073 — later allocations mainly associated with Vodacom and MTN
• 074 and 062 — later allocations associated with Cell C
• 060–069 range — allocated across multiple operators over time
At this stage, seeing a prefix like 082 or 072 reliably told you which network you were calling.
Why Prefixes No Longer Tell the Full Story
The biggest change came with the introduction of mobile number portability. This allows users to switch networks while keeping their original cellphone number.
Once portability became widespread, the prefix stopped being a guaranteed indicator of the current network. A number that started life as an 082 Vodacom number could later be moved to MTN, Telkom, or another operator — without changing a single digit.
Because of this, the prefix now reflects where the number was originally issued, not necessarily where it is currently hosted.
What Prefixes Still Indicate Today
Even though prefixes are no longer definitive, they still provide a useful historical clue:
• 082 and 072 — originally Vodacom allocations
• 083 and 073 — originally MTN allocations
• 084, 074 and 062 — originally Cell C allocations
• 081 — originally Telkom Mobile
However, due to number portability, any of these numbers may now be active on a different network.
In practice, this means you can no longer rely on the prefix alone to determine call costs, network-specific benefits, or which towers a phone will connect to.
What About Other Prefixes Like 076, 078 and 079?
As demand for mobile numbers increased, operators were given access to additional number blocks. Prefixes such as 076, 078 and 079 were issued in later phases and followed the same rules as earlier allocations.
Just like the older prefixes, these numbers may also have been ported between networks, further reducing the reliability of prefixes as a network identifier.
What a Cellphone Prefix Really Means in 2026
Today, a cellphone number prefix should be viewed as a historical indicator, not a guarantee. It tells you which network originally issued the number, but not necessarily which network currently provides the service.
If you need to know a number’s current network — for billing, SMS routing, or business systems — the only reliable approach is to use a live network lookup or confirm directly with the person or organisation involved.
Quick Summary
• Cellphone prefixes like 082, 072 and 062 were originally tied to specific networks
• Number portability means prefixes no longer guarantee the current operator
• The prefix shows where the number started, not where it is now
• Modern South African mobile numbers can move freely between networks
