A National Population Registry keeps track of "every single individual who comprises the population of the country," and verifies each individual's identity.
A national Catalog of Foreigners tracks foreign tourists and immigrants and assigns each individual with a unique tracking number.
Under Mexican law, illegal immigration is a felony. The General Law on Population States… "A penalty of up to two years in prison and a fine of three hundred to five thousand pesos will be imposed on the foreigner who enters the country illegally." (source)
