I still have my TM6 from four years ago. Will it still be valid?

Nope, best you get a new one.

If you care to take a look at it, it says 'departure card'. So it stands to reason that it is valid until you depart. They used to request the card number when doing a 90 day report, but they have stopped doing that now so it's possible it may no longer be relevant, but there's no harm in hanging on to it. It doesn't weigh a lot does it.

OP, your old TM6 has no relevance.

 

If the new online TM6 commences May 1 then to enter Thailand after that you will do the online TM6.

It's a quick reference for when I do my retirement visa without having to thumb through multiple stamps.

I still have mine from 2017 , I thought the number was required when we do the yearly extension and if you have to do the 90 day at your office ?

Technically yes it's still required if you have one.
