What makes up an Argentina address?
Argentina addresses usually put the street name first and the house number after it, with optional Piso (floor) and Depto. (unit). The next line holds the 8-character CPA postal code and the city. With a CPA you can omit the province because the first letter already encodes it.
Four-line layout
| Line 1 | Street + house number (use N° for numbered street names) |
|---|---|
| Line 2 | Piso / Depto. (optional) |
| Line 3 | CPA + city |
| Line 4 | ARGENTINA (province optional when CPA is present) |
Postal codes
The current CPA (Código Postal Argentino) is 8 characters: one province letter + 4 digits + 3 letters (e.g. C1426BMD), uppercase with no spaces. The old 4-digit codes have not been maintained since 1974. A practical check is ^[A-HJ-NP-Z]\d{4}[A-Z]{3}$; uppercase and strip spaces on input. Accept 4-digit codes only when you must support legacy data.
Form testing checklist
Accept 8-character CPA, uppercase and strip spaces; make province optional; keep street name before house number. For a broader address-form checklist, see US address form test cases
Typical use cases
Useful for street-before-number order, CPA structure, optional floor/unit lines, and optional province fields. Use country code AR and phone prefix +54.
How to use test data
In development you can use these samples to check field length, line breaks, international characters, and responsive layouts. For payment, identity, logistics, or compliance flows, use official sandbox data from your provider—do not submit these samples to live systems.
