the Pink ID card has no benefits since most Thais never seen one. For travel and ID use you're drivers licens to check in to hotels, flights etc. What you real want is the Yellow house book, that makes life easier, no need certificate of residency from immigration
my first extension immigration nakhon si thammarat wanted to see the pho yai in person, after that copy of his tabien baan, his Thai ID and pho yai ID 😁
