Postal-prefix test records - synthetic suffix
Argentina Address Generator
Argentine CPA-shaped test addresses using a source province letter and four-digit locality code. Three synthetic letters complete the eight-character test CPA.
Source-matched postal prefix. Street and remaining postcode characters are synthetic, not delivery-verified.
Argentina Address Format
The CPA format combines one province letter, four digits and three final letters before the locality. The synthetic road name precedes its building number. Where the standard source provides four digits and a separate province letter, the build combines those source fields; only the final three characters are generated.
Calle de Prueba 250 B1761GGG 20 DE JUNIO ARGENTINA
Synthetic format example, not a delivery address. The street or box line is generated test data.

GeoNames does not provide the complete block-level CPA assignment used by this tool. The final letters are not checked against Correo Argentino and are unrelated to the synthetic building number. The province selector includes only source groups with retained records, not a promise that every Argentine delivery area appears.

Counts describe this imported subset, not a national completeness percentage. A locality label may occur in more than one source group. Exact duplicates are removed; unsupported or inconsistent records are omitted, not repaired with guessed geography.
Argentina Form-Testing Cases
Argentine forms should distinguish older four-digit postcode fields from the full alphanumeric CPA. These test records exercise the latter's shape and preserve its initial letter. A validator must not strip all letters or parse the CPA as a number. Format acceptance still does not establish a real delivery point.
Generated records are for development, QA and demonstrations. They must not be used for mail delivery, identity checks, account verification or proof of residence. A synthetic result can coincidentally resemble an existing address; it is not guaranteed to be nonexistent.

Argentina Address FAQ
Are the final three CPA letters assigned to the generated street block?
No. They are synthetic. The export retains the source prefix separately so a consumer can tell which part is sourced and which part was added for a format test.
