Thailand has its own ten digits, written ๐–๙. They represent the same values as 0–9 and work in the same decimal system. For example, ๒๕ means 25, and ๑๐๐ means 100.
Where you may see Thai digits
They still appear in some official documents and government correspondence. You can also spot them on Thai banknotes or in traditional lettering. Official paperwork is not always written entirely with Thai digits: Arabic digits are also used, depending on the document and the organisation.
What is more common today?
In everyday life, the familiar Arabic digits 0–9 are more common. Prices, phone numbers and online services generally use them. Thai digits have not disappeared, but you will not need them for every shop visit or message. Learning to recognise the ten shapes makes occasional documents and signs much easier to read.
