If you are a KRN 1 then worry, If you are a KRN 2 then you are good.
By 24 November 2024 ALL prepaid meters in South Africa will need to be recoded.
The current Token Identifier (TID) code will expire on 24 November 2024 and after this date all Standard Transfer Specification (STS) compliant meters will stop accepting credit tokens. Most meters in the country fall within this category. This project is known as the Key Revision Number (KRN) rollover project.
See: What is KRN and Why Should You Care? for more info.
This project is a customer DIY rollover. As a prepaid meter user, you will be guided on how to recode your own meter. It is very easy. Just follow three steps, and you are done!
Your two key change tokens will be issued when you purchase electricity when your area is active.
You will need to follow these steps:
- Enter the first of the 20-digit codes into the system and wait for it to be accepted.
- After the code has been accepted, the second 20-digit code must be entered.
- A third code – which is the top-up token – can then be entered. Customers will know the system has been successfully updated when the top-up token is successfully loaded.
Some customers will have done this ages ago, some properties and prepaid meters will have new owners and many are now asking HOW they will see whether their prepaid meters have been recoded or not.
In order to see if your prepaid meter is recoded and will work after 24 November 2024 see below:
- When next you purchase electricity examine the slip given to you with your TID Code
- Towards the bottom of your slip you will see a reference to KRN
- If the number after/below KRN is 1 then your meter has NOT been upgraded yet
- If the number after/below KRN is 2 then your meter HAS been upgraded.
