Extended Validation Certificate

Also known as: EV certificate, EV SSL

Definition

A TLS certificate issued only after a CA performs a strict, standardised verification of the legal identity, physical existence and authority of the requesting organisation.

Extended Validation (EV) certificates follow the CA/Browser Forum Baseline and EV Guidelines, requiring proof of the legal entity name, jurisdiction, operational status and authorisation of the certificate requester. The CA performs out-of-band checks against government registries and direct contact with the organisation before issuing. The resulting certificate contains organisation identity attributes that historically triggered a green address bar in browsers; modern browsers have removed the prominent UI but the validated identity is still exposed in the certificate viewer and can be consumed by applications. EV certificates are most useful where strong proof of organisational identity matters, such as banking, e-commerce and government services.

Examples

  • A national bank using an EV certificate for its online banking domain.
  • A government tax-filing portal that issues an EV certificate to assert its legal entity.
