Who should I list as the contact person and phone number for my 90-day report in Thailand?

The discussion revolves around filling out the TM.47 form for a 90-day immigration report in Thailand. The original poster is uncertain about whom to list as the contact person and phone number. Responses suggest that the contact person should be the individual submitting the report, and the phone number is optional. It is also recommended to leave the phone number field blank and select the option to use login information.
