# Adds support for Argentine ID types

## What’s new

Adds support for two Argentine ID number types: `ar_dni` (Documento Nacional de Identidad) and `ar_cuit` (Código Único de Identificación Tributaria). Use these types when you create or update [Accounts](https://docs.stripe.com/api/v2/core/accounts/object.md?api-version=2025-11-17.preview) and [Persons](https://docs.stripe.com/api/v2/core/persons.md?api-version=2025-11-17.preview) for individuals and businesses in Argentina.

## Impact

If you work with users or businesses in Argentina, you can now collect and store DNI or CUIT numbers in the [id_numbers](https://docs.stripe.com/api/v2/core/accounts/object.md?api-version=2025-11-17.preview#v2_account_object-identity-business_details-id_numbers) field. This improves identity verification and compliance for accounts in Argentina.
