Domain Knowledge

One uppercase letter for the household-registration office, then nine digits. The first digit is 1 for a male and 2 for a female citizen (8 or 9 for a foreign resident), and the last digit is a check digit. The letter is converted to a two-digit number (A=10, B=11 and so on in the official order A-H, J-N, P-V, X, Y, W, Z, I, O), the eleven resulting digits are multiplied by the weights 1,9,8,7,6,5,4,3,2,1,1, and the sum must be a multiple of 10.

Where to find it: Printed on the National Identification Card (國民身分證) and used for National Health Insurance, banking, tax filing and household registration.
