Singapore car number plate n checksum character

example: SXY 1234 Z
Only 2 letters of the prefix are used in the checksum, for now, so discard the S.

The 2 relevant letters of prefix, X and Y, are converted to numeric value where A => 1 and Z => 26.

Coefficients (aka weights) for the 2 alphabetic prefix positions and the 4 numeric positions are:

position: weight
X : 9
Y : 4
1 : 5
2 : 4
3 : 3
4 : 2

multiply each position by its weight.
Sum up all the products,
Take MOD 19 of the sum. This is the checksum. Look up the letter according to this:

0 A
1 Z
2 Y
3 X
4 U
5 T
6 S
7 R
8 P
9 M
10 L
11 K
12 J
13 H
14 G
15 E
16 D
17 C
18 B

Or you can do "19 minus the mod19" and use a slightly different final lookup, but that's longwinded.

Number 1 Plate in Singapore
« Reply #2 on: October 02, 2009, 04:25:38 AM »
saw a number 1 plate recently and did a search. this came up.

Quote
first suffixes of major prefix series.. if u need to get the other numbers' suffixes in these series, pls derive on ur own first using the same old method before i compile them into my script.. what is shown here is indicative that it can be or will be registered but need not have been registered by someone already, especially the S?, SF? and SZ? series.. it follows that those series whose first suffix is 'Z' is the same series as SBS and 'E' is same as TIB..

from one series to another corrsponding series, the jump is 2 places right from the same cycled ordering (e.g. "ECAYUSPLJGDBZXTRMKH" )..

Owners need not register new vehicles to retain registration numbers

 
From 22 December 2003, the Land and Transport Authority (LTA) will be introducing changes to the scheme on the retention of vehicle registration numbers.

These changes will enable vehicle owners to enjoy greater flexibility to use their retained vehicle registration numbers after the vehicles are de-registered. These changes are being introduced following feedback from members of the public.

The changes are as follows:

1. A vehicle owner can transfer the retained vehicle registration number to an existing vehicle he owns. Previously, the retained vehicle registration number could only be used to register a new vehicle.

2. A vehicle owner will have up to 12 months to use the retained vehicle registration number. Previously, the existing registration number had to be used to register a new vehicle within 6 months.

The following table gives the breakdown of the charges:

Description

Charges

To use a retained number on an existing vehicle

$1300

Six-month extension of 12-month validity period to use a retained number (up to two extensions allowed)

$1,020 per extension (including $20 administrative fee)

For further information, please call LTA's Customer Service Line: 1800-CALL LTA (1800 - 2255 582) or visit the One.Motoring website at http://www.onemotoring.com.sg/

Checksum

The checksum letter is calculated by converting the letters into a number, i.e. where A=1 and Z=26, giving 7 individual numbers from each registration plate. SBA 1234 would therefore give 19, 2, 1, 1, 2, 3 and 4. Each individual number is then multiplied by 7 fixed numbers. These are added up, then divided by 19. The remainder corresponds to one of the 19 letters used. In the case of SBA 1234, the final letter should be a T.

Singapore Number plates
« Reply #13 on: November 15, 2010, 03:19:36 AM »
Quote from: wilman2772;
Private car licence plate numbers began in the early 1900s when Singapore was one of the four Straits Settlements, with a single prefix 'S', then adding a suffix letter S 'A' to S 'Y', but skipping a few like S 'H' and S 'Z' (reserved for taxis and buses), S 'D' (reserved for municipal vehicles), and S 'G' for goods vehicles large and small. No changes were made when Singapore became independent in 1965. Later, the suffix was added. Previously there was no suffix, for example, SS1234, as in the vehicle registration plates of Malaysia.
When 'S' was exhausted at SY, in January 1972, Private cars started with E, Motorbikes with A and Goods Vehicles under 3 tonnes with Y. E was followed by EA, EB with the letters EC in 1973 up to EZ. From 1984, the "S" series of number plates was launched again, but now with two serial suffix letters, starting from SBA. Currently, as of this writing, the SJY series is in issue for private cars.
Other classes of vehicles have registration numbers beginning with specific letters:
  • A series: Motorcycles (used until 1980)
  • CB series: Company or school buses
  • F series: Motorcycles
  • FB series: Motorcycles [Ex. FBA, FBB...], m/cycle plate started in end of December 2005
  • G series: Goods vehicles (class 3) [GA-GZ,GBA..GBB]etc
  • P series: Private buses (PA, PB, PC, PH, PZ were used to separate Private bus, Pte Hire etc, subsequently they were not issued and all are issued under PA
  • Q series: Company vehicles (QBx, QCx etc, except QX and QY)
  • SH series: Taxies or Street Hire vehicles (SJE - Singapore-Johore Express)
  • W series: Heavy vehicles (class 5) (Currently issuing WD)
  • X series: Heavy vehicles (class 5) (Currently issuing XD)
  • Y series: Heavy vehicles (class 3/4/5)
In addition, the following are controlled for specific types of vehicles, including:
Special prefixes were used for specific events, such as:

Re: Singapore car number plate n checksum character

update on the first post.
here's something from yahoo.
Quote
If we take a car plate number, for example SFX 9305, and we want to find the last letter (called a checksum digit), we first have to convert the letters into numbers. Each number corresponds to its position in the alphabet, i.e. A is the first letter so A = 1. Also, the S in the front is discarded; it does not take a part in the operation. From here, we get the numbers 6/24/9/3/0/5. We must then multiply the numbers in the sequence by certain constants. The constants are: 14/2/12/2/11/1. Therefore, it will become:

6*14 = 96
24*2 = 48
9*12 = 108
3*2 = 6
0*11 = 0
5*1 = 5

We have to take the sum of these numbers:
84+48+108+6+0+5 = 251

And apply modulus operation 19 on it. In this case, we divide 251 by 19, obtaining the remainder 4.

The number 4 corresponds to a letter, and in this case that letter is P.

P.S. We divide by 19 because 7 letters are omitted from the alphabet; namely F, I, N, O, Q, V and W. Therefore 26(the number of letters in the alphabet) minus 7 equals to 19.
