In fact many Land Transport departments don’t know anything about IDPs. Appendix 7 of the Vienna treaty states that the frontpage of the IDP must be in the language of the issuing country.
But my IDP was refused because the validity on the frontpage was stamped with “maart” which is Dutch for March.
I showed the supervisor the appendix of the treaty but he refused. “Thailand IDPs have English and your country must do the same.”
(Which is incorrect)
I had to fly to Bangkok and ask for an English translation at the Dutch embassy (with their official stamps). 🙄
In my case that was getting an import permit. Not specifically "immigration procedure" but immigration related. I showed my drivers license but that wasn't accepted. Then I took my Pink ID and all was well.
Apply for facial recognition at SCB, get Thai prices at various tourist places, get you a PIN, ease up on several immigration procedures. Just to name a few.
I managed an IT department of 20 employees. We installed anti-theft firmware on all laptops, continuously reporting the location of the laptop and mandating use of anti-virus and VPN.
No way anyone could simulate a different location.
