Last known plate

The 'Last known plate' feature matches a tag in your account with the last licence plate detected using it. If you have multiple tags, the 'Last known plate' feature makes it easier to: 

  • Identify which tag is in which vehicle
  • Work out if any tags are lost or not beeping without having to rely on your tag serial number
  • Reconcile tag-based trips on your account with your trip history

Your 'Last known plate' gets updated when our tolling system detects your tag in a vehicle. This also includes the date it was detected and the licence plate number. 

How to find the 'Last known plate' of a tag

  • Online
  • Linkt app
  1. Log in to your account
  2. Select 'Tags and holders' from the menu
  3. The 'Last known plate' for each tag will be shown
  1. Open the Linkt app
  2. Select the 'Account' tab 
  3. Select 'Tags' 
  4. The 'Last known plate' for each tag will be shown

When your last known plate is 'unknown'

If you travel infrequently, or your licence plate number wasn't detected, the last known plate may show as 'unknown'. The last known plate will update the next time you travel and we detect both your licence plate number and your tag. 

Keep vehicles on your account up to date

If your tag is detected in a vehicle that isn’t on your account, the licence plate number will be highlighted in red and an 'Add to account' button will display for you to click on.

If you continue to travel in a vehicle not listed on your account and the tag stops working, the vehicle's owner will receive a toll notice.

To help ensure a toll invoice isn't issued because a tag hasn't been detected, log in to your account and add all the vehicles using your tag. If you’re only using a vehicle for a short time, you can set a start and end date, or add it then remove it again later.

Do I need to allocate tags to my licence plates?

No, our systems match tags to vehicle licence plates automatically.
