I own a condo in Bangkok and I try to register a new account today on the website. https://extranet.immigration.go.th/fn24online/#
My condo is located in Bangkok (as a province), Watthana (as a district), Phra Khanong Nuea (as a sub-district).
When I come to the address section, I notice province, district and sub-district are all restricted by the drop down menu with locations already pre-set in the system. I was able to select and put in Bangkok as a province, but I could not locate Watthana as a district, nor could I continue to select sub-district.
I did some research to have a full list of districts in Bangkok and then sample checked against the pre-defined districts in the drop down menu. I noticed that not all the districts are available for selection.
I appreciate suggestion on how I can proceed.
