I had both my injections administered at Bang Sue station.
After the first one in July, I was given a white receipt paper.
This told me when my second vaccination was in October, but had no thirteen digit number on it.
Only my name, age and address.
After getting my second vaccination last week, I was only given back my yellow vaccination screening and consent form, which I had just filled in, prior to the injection.
No thirteen digit number, but a QR sticker.
I requested a receipt with the thirteen digit number, whereby I was directed to another section.
After I explained to the girl, she attempted to sort this out for me, but she had some problem with what was printed out.
Whereby we went to another section.
This time all went well and I was issued a yellow Thailand National Certificate of Covid-19 Vaccination.
This had my my name, DOB, passport details, complete vaccination details and the thirteen digit number.
When I downloaded Mor Prom and entered the magical thirteen digit number, everything was there.
Hope this helps.
