Dear Mosin Khan,

Thank you for contacting Q&A Forum.

Azure AI Language's PII detection service does support the Italian language; however, it currently does not include built-in support for detecting certain country-specific identifiers, such as:

• Italian Driver’s License IDs (e.g., AB1234567)
• Italian VAT Numbers (e.g., IT12345678901)

These identifiers are not part of the default entity recognizers used by the service, which focuses primarily on globally common PII types like names, emails, phone numbers, and credit card numbers.

To address this limitation, we suggest the following options:

1. Custom Pre/Post-Processing: Use regular expressions to detect these identifiers before or after calling the Azure PII API.

2. Microsoft Presidio: Consider using Microsoft Presidio, an open-source PII detection tool that allows you to define custom recognizers for specific patterns like Italian IDs and VAT numbers.
