Prepaid meter KRN1/KRN2 check

KRN1/KRN2 checks relate to prepaid meter key revision and token rollover readiness. Because this is meter-specific, use official municipality, Eskom or vendor instructions rather than social-media code lists.

Quick Answer

Meaning

Your meter may need confirmation of its key revision status before it continues accepting future prepaid tokens.

Most likely cause

The meter may still be on an older key revision, may need official update tokens, or the vendor may need to confirm TID rollover readiness.

First thing to try

Check your latest official provider notice or ask your municipality, Eskom or token vendor what process applies to your meter.

Contact

Contact your municipality, Eskom or your token vendor if the issue involves account status, meter number, payments or tamper flags.

What It Usually Means

  • KRN usually refers to the key revision number used by prepaid electricity token systems.
  • Some meters require official update tokens or provider-led checks as part of token identifier rollover work.
  • The correct process depends on the meter, provider and vending system, so generic code lists can be risky.

What to Try First

  • Use only official instructions from your municipality, Eskom or token vendor.
  • Have your meter number and recent purchase receipt ready.
  • Do not enter random key-change codes from social media.
  • Do not buy a large token if you have been warned that the meter needs an update first.

Step-by-Step Fix

  1. Confirm your meter number from the keypad or physical meter.
  2. Check official notices from your municipality, Eskom or token vendor about KRN or TID rollover.
  3. Ask whether your meter needs update tokens before normal recharge tokens.
  4. Enter only the official tokens supplied for your meter, in the order provided.
  5. Keep screenshots or receipts showing the update and recharge sequence.
  6. Contact official support if the meter rejects update tokens or still will not accept normal tokens.

When to Contact the Provider

  • The token was bought for the wrong meter number.
  • The meter shows tamper, not act, connect, pairing or communication errors.
  • Payment succeeded but no token arrived.
  • You need account, debt, tariff, rollover or meter replacement help.

What Not to Do

DataCost is not the provider. Do not share OTPs, banking passwords, card details, PINs or personal identity documents with unofficial support channels.

  • Do not tamper with the meter or wiring.
  • Do not use random KRN/TID codes from unofficial websites or social media.
  • Do not share banking details, OTPs or ID documents with unofficial helpers.
  • Do not ignore official rollover notices if your meter has started rejecting tokens.
