Seeing this error? The vehicle number must follow the RTO format the portal accepts. Below are the common causes and the fixes that resolve it for most users.

Why this happens

  • The vehicle number has spaces, dashes or wrong characters.
  • A temporary/“TR” number was entered in the wrong format.
  • Defence or special-series numbers need a specific format.

How to fix it

1

Use the correct format

Enter the number without spaces, e.g. MH12AB1234. The portal validates RTO patterns.

2

For temporary numbers

Prefix temporary registrations correctly, for example TR with the series the portal expects.

3

Double-check the state code

The leading characters must match a valid RTO code.

Important
If the problem is on the portal side (maintenance or server load), no browser fix will help — confirm with a second network first.
