vCard

A vCard (Virtual Contact File, .vcf) is a standard file format for electronic business cards. It stores contact information such as name, address, phone numbers, email, and URLs in a structured format that can be imported into address books, email clients, and CRM systems.

Key Aspects

Universal Standard

Defined by RFC 6350, vCard is supported by virtually all contact management systems and email clients.

Structured Data

Stores contact details in a machine-readable format, enabling automatic import into address books.

Cross-Platform

Works across iOS, Android, Windows, macOS, and web-based email and contact applications.

Understanding the vCard Format

The vCard format has been the standard for electronic contact exchange since the mid-1990s. Now at version 4.0 (RFC 6350), it supports a wide range of contact fields including name, organization, title, phone numbers, email addresses, physical addresses, URLs, photos, and even social media handles.

In the context of email signatures, vCards are commonly attached as .vcf files or linked for download. When a recipient clicks to download a vCard, their device prompts them to add the contact to their address book. This makes it easy for recipients to save your information accurately without manual entry.
