I guess one has to live in one of these provinces or otherwise have a close connection with it to become familiar with these abbreviations. For me, living in Italy, they are incomprehensible and although having read them here now, if they crop up again in future I will probably have to ask again for an explanation.
BKK I know as the airport code for Suvarnabhumi Airport in Bangkok and I am familiar with Ubon, Udon and Korat, which I have heard come up in conversation during my visits to Thailand, but the others mean nothing to me and I am not in the mood to memorise the various abbreviations invented by members of this forum for the 76 provinces currently existing and future ones to come.
On my part, I shall continue to write my posts in a manner that they will hopefully be understood easily by a wide majority of readers, wherever in the world they may live.
