Just don’t mix up the Pink ID card and your driving licence with your TIN when dealing with Krungsri. I have now given Bangkok Bank my Pink ID card, driving licence, yellow house book, my wife’s house book, and proof of my phone number. For some reason, the head office even reprimanded the bank officer because she could not prove that we were married, even though we have never registered our marriage in Thailand and I am on a retirement visa. Should be a walk in the park from now on! We’ll register our marriage when we’re back. I’m sure a few more surprises will show up along the way. 😉
