Argentine passports are issued to citizens of Argentina by the National Registry for People (ReNaPer). They were issued exclusively by the Argentine Federal Police up to 2011. Their primary use is to facilitate international travel.
Argentine passports are valid for travel all over the world, but some countries require a visa. For traveling within South America (except the Guyanas), Argentines do not need to use a passport, as they may use their National Identity Document (DNI).
On June 15, 2012, the Argentine Interior Ministry announced the immediate introduction of biometric passports. The new passports will have unique numbers (alphanumerical combinations, with 3 letters and 6 numbers), a significant change from the current policy, where passport numbers were the national ID number of the holders (with an N after it).
