スペイン税務ID検証ツール

Validate Spanish NIF, NIE, and CIF-style tax IDs with format, prefix, and checksum checks before form submission.

Spanish Tax ID Validator lets you collect and validate Spanish NIF, NIE, and CIF-style tax identifiers directly in a Jotform field. It checks identifier format, accepted prefixes, and Spanish checksum rules before submission, helping reduce mistyped tax IDs on registration, billing, onboarding, and compliance forms.

このウィジェットを使用して出来る事：

• Collect Spanish NIF, NIE, or CIF-style identifiers from customers, suppliers, students, or members
• Validate personal and organization tax IDs with checksum rules
• Limit accepted identifier types for forms that only need NIF, NIE, or CIF values
• Store normalized uppercase values for finance and compliance workflows
• Map validation status, identifier type, and control character into other form fields

Use it when a regular text field or regex mask is not enough to verify Spanish tax ID correctness.
