Record Description

Bangkok's full ceremonial Thai name, Krungthepmahanakhon Amonrattanakosin..., runs to 168 letters in its formal transliteration and is recognized by Guinness World Records as the longest official place name on Earth. A shorter 111-letter version is used in some contexts since Thai script has no capital letters.
