They have to I believe by law - foreign tourists (not sure about non-tourists my sim is older than the law) also get different sims apparently. I’ll see if I can find a link about it.

Edit: found it. https://www.theguardian.com/world/2016/aug/10/thai-regulator...

Edit: to clarify I don’t think the two are linked specifically - most services/purchases like this in Thailand require some form of Government ID. For locals that’s usually an ID card, some places will accept my Thai drivers licence others want passport.
