What Is a Meter Number?

A meter number is a set of unique 11- or 13-digit numbers that serve as an identifier and is normally assigned to an electricity meter. This number is always unique to each meter.

What is an invalid meter number?

Once you get an invalid response, you may not be able to complete certain tasks, like buying tokens with numbers, until the issue is fixed.
Although there are different reasons that may cause an invalid meter number, the amazing thing is that it can be fixed through some measures. For the sake of clarity, we are going to list some of the possible reasons why you may get an invalid meter response and, in the same vein, enumerate different measures that you can use to resolve the issues. Let’s proceed!
Why is my meter number invalid?
As we said earlier, there are different reasons why you may get an ‘’Invalid’’ response when using your meter number. Some of the most common reasons are:
1. Wrong Meter Number
This is one of the most common reasons why you may get an invalid response when using your meter number. If you mistakenly omit or misplace one of the digits in the meter number, you are going to get an invalid response because the number will differ from the one that is stored in the metering system database. And once the system can verify the meter number, it will then return invalid as a response.
2. Old Database
If the database of your electricity is outdated, the data they stored in it may corrupt, which may lead to unintentional changes in your meter number, and when this occurs, there will be a sudden difference between your meter number and the one stored in the database, which is definitely going to disrupt the metering system, thereby forcing it not to recognize your meter again. And when the metering system doesn’t recognize your number, it won’t be able to match it to the one stored in the database, thereby returning an invalid meter number as a response. This issue is very common, even if you’ve been using it for a long time.
3. Meter Upgrade or Swaps
This is another primary reason why you may get an invalid meter number response when using the number. If you replaced or upgraded your prepaid meter recently, there are chances that your meter number will be changed, and if that happens, the new meter number may not have been reflected in your provider’s database, thereby returning an invalid response when you want to use the number.
4. System Errors or Technical Glitches
If your electricity provider’s metering system or software is experiencing technical glitches, you may also get an invalid meter number response. When there are system errors, the provider’s software won’t be able to match your meter number with that on the database.
How to Resolve Invalid Meter Number Issues
If you get invalid meter number response when you want to use your meter number, you can resolve it by trying any of these methods
- Ensure that you enter the meter number correctly and at the same time, don’t misplace the position of each digit when using the meter number
- If you replace your meter, you should ensure that your utility provider updates it on their database to match the one that you are having.
- You can reach out to your utility provider and request that they verify your meter number for you
- Finally, you can contact your provider and ask if they have technical issues, and if they have, you can wait for them to fix it to enable you to use the meter number again.
