. Yep, in some time I have the same question I guess. Maybe for me it's a bit more easy, because now I am registered in the house of my girlfriend but I/we are building a new house about 50m further. So everything stays the same except for the house number. I just ask in my local Amphur where I got it from I think. Maybe ask your new Amphur how they handle that. Would be nice to know indeed. Little bit the same for my Thai drivers license. On the back is my address too 🤷♂️
