I am trying to register online to let immigration know that I am staying here now within the 24 hour notification period but I am stuck and confused about which 2 documents on the 2 Nd page they are asking for. 1 seems to be a copy of the house id, yellow book. Which I haven't got. Only the blue book. And not sure about the second document.
TLDR : Answer Summary
The user is confused about the required documentation for online registration with immigration in Thailand under the 24-hour notification period. They question the need for a 'house ID' or a yellow book, as they only possess a blue book. Community comments emphasize that foreigners don't appear in blue books and advise obtaining a yellow book, while one comment suggests that registration must be completed by a spouse, friend, or landlord.
