How Italy tax IDs are formatted
In Italy, the tax identifier is commonly known as Codice Fiscale (Codice Fiscale). The expected format is 16 alphanumeric characters (surname + name + birthdate + place). Teams usually need a Italy Codice Fiscale check around tax filing, healthcare, employment, or before a record moves into billing, onboarding, or compliance review.

What this validator checks
Format and length
Confirms the number follows the expected Italy pattern: 16 alphanumeric characters (surname + name + birthdate + place).
Useful examples
Shows valid and invalid-looking samples so you can compare spacing, separators, letters, and digit counts before submitting real data.
When people usually check this number
- Tax filing
- Healthcare
- Employment
- Banking
A format match does not prove that a Italy tax ID belongs to a specific person or business. Use the result as a first-pass data quality check, then confirm sensitive cases with official records.

How to check a Italy Codice Fiscale
Use this check before a record reaches billing, tax reporting, or manual review.
Enter the Codice Fiscale
Paste or type the Italy tax identifier exactly as it appears in your source record. Spaces and separators are fine when they are part of the expected format.
Review the format result
Check whether the number matches the known Italy structure, including length, separators, letters, and checksum rules where public guidance includes them.
Confirm important records
For onboarding, tax reporting, or compliance work, treat the result as a data-quality signal and confirm high-risk records with Agenzia delle Entrate or your internal process.
