I had recently renewed my passport, AND received a new 1-year extension, so was a little surprised when I was sent an on-line reminder to next renew the 90-day report.. I decided to try, and as expected it was rejected when I submitted...
Unexpectedly though, it was subsequently approved (albeit with the old PP number)...
But I decided to go to my local Imm office (Rayong) who said I needn't have bothered since the 90d report was fine (..??). They did print me a new receipt with the new PP number, although with the same "next due" date as before, and assured me they'd updated their system to allow me to be able to use the online system with the new PP next time... We will see...!
