anybody knows of an OFFICIAL THAI MAIL POST OFFICE, which is conveniently located very near (walking distance not more than 200-300 meters) to a BTS or MRT station ?

thank you

Nana PO, strangely enough located near Nana BTS station, its on the suk road about 20 meters before you turn into Soi 4.

Saphan Kwai BTS has Sam Sennai post office right beside. Just down the stairs and you are there!

And Prakanong is located between the station and the soi but looks like a bomb shelter, Beirut circa 1987.

And Thonglor, there is a post office between suk 36 & 38. Quite small though.

Suk 23, out of subway (Suk stop) or Skytrain (Asoke stop), walk down Soi Cowboy, turn left at the end and is on right after about 30 yards.

Also you can search as per the webwise:
