# Future Bus Registration Numbers

This is the page for future bus registration numbers.

The suffix of the bus registration numbers is derived from the following formula.

## Checksum Formula

**SBS Registration Numbers**

2 - (5 X 1st Number) - (4 X 2nd Number) - (3 X 3rd Number) - (2 X 4th Number)

**SG Registration Numbers**

11 - (5 X 1st Number) - (4 X 2nd Number) - (3 X 3rd Number) - (2 X 4th Number)
SG9999F

**SMB Registration Numbers**

9 - (5 X 1st Number) - (4 X 2nd Number) - (3 X 3rd Number) - (2 X 4th Number)

**TIB Registration Numbers**

7 - (5 X 1st Number) - (4 X 2nd Number) - (3 X 3rd Number) - (2 X 4th Number)

Using the result, mod the number with 19, you will get a number from 0 to 18. Refer to the list below for the suffix.

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

You can mod the number by 19 using Google. For example, if the result is -156, type ' -156 mod 19 ' into the Google search bar and it would calculate the answer.

Alternatively, you may use this checksum calculator created using Google Spreadsheet to get the letters or this checksum calculator tool instead.

For the Google Spreadsheet calculator, go to File then click Make a Copy. The checksum calculator is then for your own use.
