How to Close or Deactivate South Indian Bank FASTag

If you have a FASTag issued by South Indian Bank (SIB) and wish to switch to another provider or no longer use it, you must close it properly. According to the NHAI “One Vehicle, One FASTag” rule, only one active tag is allowed per vehicle. Keeping multiple tags can result in double toll deductions or automatic cancellation by the system.

This article explains the complete process to deactivate your South Indian Bank FASTag, request refunds, and safely remove the tag.
