In this platform we encourage the use of correct postal code and also all the town names in Argentina. You can browse provinces, then towns and streets to find the Zip Code of your area. We also recommend using the official page for searching the Postal Codes in Argentina.
Implementation of the current Postal Code system in Argentina began in 1998 and is a complement to the old system with 4-digit Postal Codes. Although it is a new and more efficient system, the two systems continue to coexist to this day. The CPA expands the postal code information, incorporating 4 letters that identify each side of the square in towns with more than 500 inhabitants. Towns with less than 500 inhabitants have a single CPA.
