I was recently going through some old papers and came across what appears to be a revenue type card with 10 digits on it but all written in Thai. I vaguely remembered previously- more than 10 years ago -I claimed at revenue department a refund on tax deduction from a fixed deposit.

Would the card be used for that?

Small yellow card?

Prolly your TIN used for your tax return.

Prolly??? You mean Probably, 2 more letters to type, but shows you know proper English.

It sounds like an old TIN, which did have 10 numbers.  They have 13 now.
