Application for Covid vaccination form

[Speedo1968]

I live outside a small town about 50km south of Khon Kaen and went to a local clinic to ask about applying for vaccination.
The vaccinations were being done at the towns hospital.
At the clinic ( which I have attended as a patient in my years here ) the doctor said that I can register there for the vaccination.
I gave him a copy of my passport.
Oh dear he said the application requires an ID that has 13 numbers, your passport only has 9 numbers so I cannot register you.
He said he would try to figure out a way but I have heard nothing since.

I have looked online for the link to download the government application form or apply on line, could someone kindly send me details of the link ?
Many thanks
