The most likely meaning of “EFT GC number” is the GC/EFT number on a train ticket refund form : GC can mean Guard Certificate , and EFT can mean Excess Fare Ticket issued by the ticket examiner. In that context, the number is the reference from the issued ticket/document that you use when filing a refund or claim.

What it usually means

  • GC number : Guard Certificate number.
  • EFT number : Excess Fare Ticket number.
  • These are typically asked for when you need to enter details from a document issued by the ticket examiner, especially for refund-related paperwork.

If you saw it in a form

The form is usually asking for:

  • The number printed on the GC/EFT slip.
  • The date it was issued.
  • Sometimes the amount charged.

Common confusion

“EFT” can also mean electronic funds transfer in finance, but that is a different meaning from the train-ticket/refund context. If your form is related to rail travel or TDR/refund filing, the train-ticket meaning is the right one.

Where to find it

Look on:

  • The EFT slip or Guard Certificate given by the examiner.
  • Any ticket details or refund document that references the issued slip.
