Thailand: Banknote Serial numbers




Thai banknotes have serial numbers at top left and bottom right corners. The top left serial number has a prefix consisting of single digit Thai number and a Thai letter of alphabet followed by a 7 digit number.



100 Baht banknote



The bottom right serial number similarly has a prefix consisting of single digit Western numeral and a letter of the English alphabet followed by a 7 digit number using Western numerals.

Prefix system:
In any note, the Thai and Western numeral prefix (indicated by 1 and 4 in images) are always same.

9 Thai and 9 English letters (indicated by 2 and 5 above) are used to get various unique combinations for a batch of notes.

For a new series of banknotes (not signature change), prefixes always start from 0กA. Each combination gives a batch of 1million notes (0กA 0000000 - 0กA 9999999). See combinations below.

Disturbing that Thai currency has English writing and an English serial number. How would Americans like it if dollars had Thai serial numbers?
