Peter its like this -
When I started working , I already had PINK id and yellow book.
Went to R.D. , showed by Pink card and got same number registered as TIN.
I do not have a separate TIN, my TIN starts with 6XXXX
Whereas, people with no pink card get TIN which starts with 0XXXX
Both are 13 digits
You may open an account with Yellow Book & Pink Card, not a problem.
