Whole-plate digit sum in numerology
When the letter values and all the digits add up to 21, the plate belongs to the sum 21 group. Thai numerology rates this sum Best avoided (grade E), under the name "Led astray by confidence": A number to avoid. It tends to lead to wrong decisions and needless losses. Digit sum 21 blends the Moon and the Sun in a form the texts consider conflicting, so it tends to bring overconfidence and overlooked details. Users often lose money by trusting the wrong person or by signing documents without reading them. If you cannot avoid it, have a second person check every decision that involves money. We currently track 48 listings for plates with a digit sum of 21. They are sorted by price so you can compare within the same sum. Choose a sum together with a birth-day check, because a plate with a good sum can still contain a Kalakini (inauspicious) digit for some days.

A plate's sum is the value of the series letters, plus the series prefix digit, plus every digit of the number
Two plates with the same number but different series get different sums, because each letter has its own value in the numerology table. The method is to add the series value to the sum of the digits on the plate. If the result is exactly 21, the plate belongs on this page. The table below therefore always shows a pair: the series value and the digit sum it has to be matched with.
| Series | Series value | Digit sum | Example number |
|---|---|---|---|
| 2กก | 4 | 17 | 89 |
| ภก | 2 | 19 | 289 |
| ฆช | 5 | 16 | 1168 |
| กง | 3 | 18 | 1188 |
| ฒฒ | 6 | 15 | 168 |
| ฮบ | 7 | 14 | 68 |
| พข | 10 | 11 | 38 |
| 2กจ | 9 | 12 | 39 |
The series value is the sum of every letter in the series plus the series prefix digit. The digit sum is the total of every digit of the plate number. We use the same table for every plate on the site, so it can always be checked.
