The first banknotes bearing his His Majesty the King's image will be available on April 6, initially in three denominations.
The three denominations are 20, 50 and 100 baht, Bank of Thailand governor Veerathai Santipraphob said on Thursday.
Two other denominations - 500 and 1,000 baht - will be issued on the birthday of His Majesty King Maha Vajiralongkorn, July 28.
The front of the new banknotes will feature a portrait of His Majesty the King. The size and dimension will be the same as the banknotes circulated during the reign of the late King Rama IX, he said.
Existing banknotes will remain in circulation, he said.
April 6 is Chakri Day, which commemorates the founding of the current Chakri Dynasty.
