Argentina billing address generator
Argentina's full CPA has eight alphanumeric characters. A legacy four-digit code is not interchangeable with a full CPA.

Address information
Address format in Argentina
Write street and premises, then piso and departamento where needed. Put the complete CPA before the locality and finish with Argentina.
- Street and premises
- Place the premises after the street. Piso and Dpto. identify floor and apartment. Distinguish numerals in a street's name from the premises number.
- Postal-code format
- A CPA consists of one letter, four digits, and three letters, such as C1000ZAA. Legacy numeric codes still appear in some forms; do not invent letters to turn four digits into a full CPA.
- Region fields
- Ciudad Autonoma de Buenos Aires (CABA) is separate from Buenos Aires Province. A CPA beginning with C identifies the autonomous capital, not the surrounding province of the same name.

FAQ
What if a form only accepts four numeric digits?
Check whether the merchant explicitly uses legacy postcodes. A full CPA is more specific; stripping its letters does not validate the address. Ask the merchant about its format when the registered address cannot be entered.

Can I use a generated address as my billing address?
For an actual payment, use the billing address registered with the merchant or card issuer. Generated records and fixed examples do not establish that an address belongs to you or matches your account. This tool does not access account records or guarantee payment acceptance.
Why does the example differ from a generated result?
The fixed example illustrates field order, while generation draws records from the selected region's address data. Records may retain older administrative names. Confirm the full address and current postal code with the recipient or postal operator before use.
Billing address details
- Choose the destination country or region before entering address fields. Keep postal codes as text so leading zeroes are preserved.
- Use the building, unit, and apartment details from the registered address; a postal code cannot supply these details.
