There is a National ID Number for everyone with Salvadoran Nationality 18 and older. And also a Tax ID that anyone can apply for.

As someone from Latin America, it's funny to read about Americans' struggle for a countrywide ID and the sense of government control/ freedom.

Here in Mexico the government has our biometrics, there's a national election ID, SSN and a unique "clave de población " .
