What Is a vCard (.vcf) File?

A vCard (Virtual Contact File) is a standardized file format for electronic business cards. vCard files use the .vcf extension and store contact information such as names, phone numbers, email addresses, URLs, and more. The format is supported by virtually all contact management applications, including Apple Contacts, Google Contacts, Microsoft Outlook, and CRM systems.

vCard has gone through several versions: 2.1, 3.0, and 4.0. Version 3.0 (RFC 2426) is the most widely supported and is the format generated by our virtual contact card creator. This validator checks files against all common versions and identifies potential issues.

How to Validate Your vCard

  1. Upload a .vcf file — Click the file upload button to select a vCard file from your device.
  2. Or paste vCard text — Copy and paste the raw vCard content directly into the text area.
  3. Click "Validate" — The validator will parse your vCard and check for structural issues, missing required properties, and version compatibility.
  4. Review results — See parsed fields, errors (if any), and warnings about potential compatibility issues.

What We Check

  • Proper BEGIN:VCARD and END:VCARD delimiters
  • VERSION property presence and validity
  • FN (Formatted Name) property
  • Standard property parsing (EMAIL, TEL, ORG, URL, TITLE)
  • Property parameter handling (e.g., TEL;TYPE=WORK)

Common vCard Issues

  • Missing BEGIN:VCARD or END:VCARD markers
  • No VERSION property specified
  • Missing FN (Formatted Name) — required in v3.0+
  • Incorrect line endings or encoding
  • Invalid or outdated version numbers
