I'm not sure if the SNCF and NMBS systems work the same way, but a
Eurostar ticket issued on Tribute has three different references on it:

1) The 8 alphanumeric character Tribute Reference
2) The 6 character ERS Reference
3) The 8(?) digit ticket number (prefixed IV)

SNCFs system works by the 6 letter reference. The ticket (IV) number also
appears along with a 12-digit reference number (beginning 15) which IIRC
is the HERMES booking reference.

And, of course, you can also search by name if it was entered into the
record at the time of booking.

Presumably to narrow the search down you would have to include some
journey details in too?
