Argentina Mailing Address Formats and Other International Mailing Information

When mailing an envelope or postcard, leave at least the bottom 16 millimeters (5/8 inch) blank on both front and back. (The postal service's reading and sorting machines might need this space to print bar codes on your mail.)

• Addressing format information, somewhat focusing on postal code usage. (in Spanish, with example addresses) -->
  Some guidelines:
  • The postal code (aka CPA) should be printed with capital letters.
  • The lines of address text should be flush left.
  • You needn't write the province name; the postal code implies it.
  • "ATTN" ("At.") lines should be in the addressee part of the address, NOT down with the postal code!

  Completing/repairing a partial address Interactive map of Buenos Aires (may require Javascript; in Spanish) Surprisingly useful for helping fix over-abbreviated, incomplete or slightly broken addresses in Buenos Aires.

  You can find an address by using a search form in the lower left corner (as of 2010 June) labeled "LOCALIZADOR DE DIRECCIONES". This can be useful for getting more complete forms of abbreviated street names, and for figuring out a location within the large city. Also useful for getting an address into the more complete form sometimes required by the Argentine Post's (Correo Argentino's) postcode lookup form.

  You can check that an address at least exists with Correo Argentino's Postal Code Lookup Form (Requires Javascript; in Spanish)
