The gender codes are as follows:
– For citizens born in the 20th century (from 1900 to 1999): Male = 0, Female = 1
– For citizens born in the 21st century (from 2000 to 2099): Male = 2, Female = 3
– For citizens born in the 22nd century (from 2100 to 2199): Male = 4, Female = 5
– For citizens born in the 23rd century (from 2200 to 2299): Male = 6, Female = 7
– For citizens born in the 24th century (from 2300 to 2399): Male = 8, Female = 9
Birth Year Code
The last two digits of the birth year of the citizen are used as the birth year code.
For example, if your Personal Identity Card number is: 079097000123, then:
– 079 is the code for Ho Chi Minh City
– 0 indicates male gender, born in the 20th century
– 97 indicates the citizen was born in 1997
– 000123 is a random sequence of numbers.
So, you only need to memorize the last 6 digits, and you don’t have to remember the first 6 digits if you understand the rules.
