Why Numerology Texts Disagree on a Plate's Digit Sum and Pairs
Compares three ways of counting the digit sum on a single plate, with an example whose grade ranges from A to C, and a guide to choosing when you find texts that contradict each other on digit sums, digit pairs and birth-day numbers.

Two websites disagreeing does not mean someone added wrong
People who check the same license plate on several websites often get different answers. One site says the digit sum is excellent, another says it is average. The difference can arise at three levels. The first is how the digit sum is counted. The second is the meaning the texts give to the same sum. The third is the choice of which numbers count as lucky for a birth day.
This article goes through each level with real numbers, to show that most disagreements are not mistakes but different choices. Once you know where the difference lies, you can choose for yourself which set to believe.
Level one: three ways to count the digit sum
The example plate is 1กท 2345. Adding only the plate number digits, 2 3 4 5, gives 14. Adding the series prefix digit 1 as well gives 15. Counting the consonants ก and ท too, each worth 1, gives 17. All three values are correct by their own counting method.
The knock-on difference is the grade. Sums of 14 and 15 are grade A in this site's table, but a sum of 17 is grade C. So the same plate can be called excellent or average depending on what a site counts. This site counts every part on the plate, because these are the letters and digits you actually see, and it shows the breakdown so every character can be checked.
When results disagree, ask three questions before concluding who is wrong. One, do they count the consonants? Two, do they count the series prefix digit? Three, does the consonant value table they use match the one you use? These three points are covered in detail in the article on how to calculate a car plate's digit sum.
| Counting method | What is counted | Digit sum | Grade in this site's table | Meaning given by the table |
|---|---|---|---|---|
| Plate number only | Adds only the plate number digits, without the series prefix digit or the consonants | 14 | A | Brisk trade, money flowing well |
| Series prefix digit plus plate number | Adds every digit visible on the plate, including the series prefix digit, but not the consonants | 15 | A | Goodwill and popularity (เมตตามหานิยม) |
| Including consonants | Adds the value of every consonant, the series prefix digit and the plate number; this is the method this site uses | 17 | C | A fighter who must wait for the right time |
Level two: same digit sum, different meanings
Even when the digit sum is counted the same way, the meaning the texts give that number may differ. A common example is the sum 3. Some schools say it means a hot temper and a risk of accidents, while others say it boosts trade and investment. This site's table rates a sum of 3 as grade D, which reflects a choice of one set of texts and does not mean the other set is wrong.
For single-digit sums such as 2, 4, 5, 6 and 9, some tables put them in the good group, while this site's table gives them average to good grades. This is a matter of how much weight each text is given. There is no central authority that every school accepts.
| Digit sum | Grade in this site's table | What other schools say |
|---|---|---|
| 3 | D | Some schools say a hot temper and a risk of accidents, others say it boosts trade and investment |
| 2 4 5 6 | C C C C | Some tables put these single-digit sums in the good group |
| 9 | B | Some tables put it in the very good group |
Level three: birth-day lucky numbers and enemy digit pairs
On lucky numbers for each birth day there is a direct contradiction: some sources recommend the digit 6 for people born on Sunday, even though under Taksa (ทักษา) 6 is Sunday's Kalakini (กาลกิณี). This site follows Taksa because it is the principle most texts agree on, and it is also used for naming and choosing auspicious times.
Another example is enemy pairs by planet. One line of texts holds that the Sun and Mars, the Moon and Jupiter, Mercury and Rahu, and Venus and Saturn are enemy pairs, so adjacent digit pairs on a plate such as 13, 31, 25, 52, 48, 84, 67 and 76 get a warning. This site's digit pair table agrees on almost every pair, except 25 and 52, which this site grades B and C.
Some sources also warn that the pairs 68 and 86 mean money will not stay with you, while this site's table grades both pairs B, and Chinese numerology is very fond of these numbers. This is an example of two schools using entirely different systems, so their results are opposite.
| Planet pair | Digit pairs | Digit pair grade in this site's table |
|---|---|---|
| Sun and Mars | 13 and 31 | D and D |
| Moon and Jupiter | 25 and 52 | B and C |
| Mercury and Rahu | 48 and 84 | E and E |
| Venus and Saturn | 67 and 76 | D and D |
What to do when the texts contradict each other
First, pick one school and use it consistently. Mixing several schools produces so many exceptions that you cannot decide. Second, use your birth day's Kalakini as the first filter, because it is the point most texts agree on. Third, if schools disagree about a number, check first whether the plate is reasonably priced, because a number the texts disagree on should not be a reason to pay more.
All of this is belief based on traditional texts. No side has been able to prove its effects, so choose for the owner's peace of mind, and always compare the market median before deciding.

FAQ on this topic
Does this site agree with other websites?
This site's digit sum counts every part: the consonants, the series prefix digit and the plate number. Sites that count less will get a lower sum, so the results may differ. This site shows the breakdown so you can check every character.
Which school should I believe?
There is no central school that everyone accepts. Choose the school you are comfortable with and use it consistently. Kalakini by birth day is the point most texts agree on, so you can use it as your first criterion.
Does the digit sum of the same plate change with the birth day?
The digit sum does not change with the birth day. What changes with the birth day is Kalakini and the fortune-boosting numbers, which are calculated separately from the digit sum.
