BIMI Mark Certificate designed for government bodies — verified identity, anti-impersonation protection.

A Government Mark Certificate (GMC) authenticates a government body's official seal or logo for BIMI display in citizen-facing email.

What is a Government Mark Certificate (GMC)?

A GMC is a BIMI Mark Certificate specifically designed for verified government entities. It authenticates a government body's official seal or logo and enables its display in BIMI-supporting email inboxes. Government email impersonation — scammers pretending to be tax authorities, health agencies, or law enforcement — is a major public harm. A GMC gives legitimate government senders a visual authenticity signal that citizens and mail clients can trust.

Questions

Frequently asked questions

What makes GMC different from VMC and CMC?
VMC is for commercial brands with registered trademarks. CMC is for established brands without trademarks. GMC is specifically designed for verified government entities — it validates government identity rather than trademark or commercial use.
What documentation is required for a GMC?
SSL.com verifies your government entity status through official records. Documentation requirements vary by jurisdiction but typically include official government registration and proof of authority to act on behalf of the government body.
Does GMC require DMARC?
Yes — like all BIMI certificates, a GMC requires strict DMARC enforcement (quarantine or reject) on the sending domain. Ensure DMARC, DKIM, and SPF are fully deployed before applying.
Which inboxes will display the government seal?
Any inbox supporting BIMI with Mark Certificate validation — including Gmail, Apple Mail, and Yahoo Mail. BIMI adoption continues to grow across major email providers.
Can state-level or municipal governments apply?
Yes — GMC is not limited to national governments. Regional, state, and municipal government bodies are eligible, subject to verification of their government entity status.
