Ubonjoe. Wish they would have given me the TM6 number so I could use it to do the 90 day report online. She just told me to get another TM6 from an airline. I will get one and take it with me next time I go to Jomtien Imm. so they can change my number. They just scanned the bar code of the old notification receipt and give me a new blue paper. Done in 2 minutes.

Perhaps you wrongly assumed by stating you'd 'lost it' they would look it up and replace your TM6.

 

Every office may have it's own unique system in dealing with a lost TM6.

My IO have a duplicate book specifically for this purpose. They will find your TM6 number, enter the details in the book, give you a receipt with the details and staple it in your passport.

report it to the police or immigration asap

Well as fate happens I found my lost TM6 yesterday. Will try to put the number in next 90 day report online. If not back to Jomtien Imm.
