Format, years and the law

Format
9999, for example กข 1234 (9 any digit)
  • category_letter_1: delegated
  • category_letter_2: delegated
  • province: the name of Bangkok or of the province of registration, spelled out; the word เบตง where the vehicle is registered at Betong District, Yala Province

The two letters name the issue series, the first runs in blocks tied to the vehicle class, and Thais recite them by their letter names: a กข plate reads aloud as "chicken, egg". The bottom line spells the registering province out in full; no code table needed.

ขส
กรมการขนส่งทางบก (Department of Land Transport, its abbreviation, embossed in a circle at lower right)

The format above is broad: a registration that fits it has the right shape, which does not show that this series issued it.

About this plate
What IS new in 2011 is the size (the 2547 sizes are in the revoked instrument, not secured here) and the leading-numeral exhaustion rule the หมายเหตุ explains. Thai press dates the modern arrangement to 1997 and Bangkok's first leading-numeral series to 2012; neither was pinned to an instrument and neither is asserted.
How numbers are issued
A letter pair runs 1..9999 and the registrar then moves to the next pair the Director-General has opened; when the pairs are exhausted the leading numeral 1-9 is prefixed and the pairs restart. The pair-opening ORDER is not published in any instrument secured here, so no age inference is offered, this is the single biggest gap for a parse API.
About the format
The pattern is the REGISTRATION NUMBER ONLY. The printed mark is two lines: line 1 = [optional leading numeral 1-9] + category letter 1 + category letter 2 + the registration number of not more than four digits; line 2 = the province name in Thai.
