This has been problematic on more than one occasion.  Logically,  there was only one visa - the original Non-Immigrant O - with annual extensions coming after that (though all pqassport stamps bear some kind of sequential number).  These are the "numbers" for myself & dependent wife, respectively, issued in Chiang Mai -

2014 non-imm O visa - B2699563 & B2699564 

2014 annual extn - 20928/57 & 20929/57 (though hard to read)

2015 annual extn - 58/PN/2858 & 58/PN/2859

2016 annual extn - 59/PN/7591 & 59/PN/7593

2017 annual extn - 60/RT8405 & 60/DRT8406 

I presume we should always be quoting the first "B" numbers.  Is this correct?

Thanks in anticipation.

What did you put on the card for all the other renewals?

I have read on here, that you put the re-entry visa number on your TM6. And if you 'lose' your TM6. you fill in a new one at Immigration, and they will tell you which number to put on.

I think we must have been quoting the sequential numbers on the annual extensions.  

If you have a still valid visa issued by a Thai Consulate allowing multi-entry you put that number.  If you are on an extension of stay you put the number of your re-entry permit.  Extensions of stay by themselves do not allow any entry.

You seem to be on a extention of stay...

You would put you ReEntry Permit number..

If you forgot to get one before leaving the

country you must start all over...

No. You should put the re-entry permit number on the TM.6.

 

As long as the IO sees/finds the re-entry permit they will use it regardless of what you write on the TM.6.
