Argentina Address Format Guide
Argentina introduced its current CPA (Código Postal Argentino) format in 2000: a letter, then 4 digits, then 3 more letters (e.g. C1425DTE). The leading letter identifies the province or autonomous city (Buenos Aires City addresses always start with C), giving the code more locating precision than the older purely-numeric postcode. The standard address format is: street + house number, city, province, CP + postcode, Argentina. Note that some international-facing forms still only accept the old 4-digit postcode, in which case you can extract just the 4 digits from the middle of the CPA.

FAQ
What format is the Argentine CPA postcode?
A CPA (Código Postal Argentino) is a letter, then 4 digits, then 3 letters (e.g. C1425DTE). The leading letter identifies the province or autonomous city, the 4 digits correspond to the old traditional postcode zone, and the trailing letters narrow it down further, sometimes to a specific side of a block.
How does the CPA relate to the old 4-digit postcode?
The CPA was introduced after 2000, adding letters before and after the traditional 4-digit postcode to carry more precise location information. If an international form only accepts a 4-digit postcode, you can usually just extract the 4 digits from the middle of the CPA.
Does it cover all 23 Argentine provinces plus Buenos Aires City?
Yes, you can specify one or generate randomly.
Can these addresses be used for real deliveries?
No, the generated results are fictional test data intended only for format reference and development testing.
