This guide lists major trademark offices and intellectual property authorities commonly used during VMC trademark validation, including trademark offices such as USPTO, EUIPO, UKIPO, CIPO, IP Australia, and other recognized jurisdictions.
Why Does VMC Require a Trademark?
Verified Mark Certificates (VMCs) require a valid trademark registration because mailbox providers and Certificate Authorities must verify that your organization legally owns the logo being displayed in email inboxes.
Trademark validation helps prevent:
- Brand impersonation
- Fake logos in inboxes
- Phishing abuse
- Unauthorized logo usage
For Gmail specifically, trademark verification is also required for the blue verified checkmark experience.

Important VMC Trademark Validation Notes
Trademark acceptance depends on multiple factors beyond the trademark office itself.
Certificate Authorities may additionally review:
- Trademark status (active/approved)
- Trademark ownership
- Exact logo matching
- Jurisdiction
- Mark type (word mark vs figurative mark)
- Public verification availability
Final approval always remains subject to Certificate Authority validation policies.

Frequently Asked Questions
Can I use a word mark for a VMC Certificate?
Yes, word marks do qualify for VMC certificates. If your trademark is registered as a word mark, the logo used for the certificate may still use your preferred font, font size, capitalization, and colors.
However, the logo must remain plain text only. Figurative elements, icons, symbols, or decorative design components are generally not allowed unless they are separately protected under a figurative/logo trademark registration.
Many trademark offices explicitly mention this flexibility within the trademark description itself.
Can I apply for a VMC if my trademark is still pending?
Most Certificate Authorities require the trademark to be fully approved and active before a VMC certificate can be issued. Pending trademark applications are generally not accepted for final VMC validation.
However, if your trademark is already in the final stages of approval, you can begin with your purchase process in advance. It’s better to start early because internal procurement processes, legal reviews, payment approvals, and information exchange can take time.
While the certificate issuance itself will remain on hold until the trademark becomes fully approved, starting the process early can help reduce delays once the trademark registration is finalized.
Additionally, the certificate validity period starts from the day the certificate is issued — not from the purchase date — so beginning the process early does not reduce the usable validity of the certificate.
What if I don’t have a trademark?
You may still qualify for a Common Mark Certificate (CMC). CMC certificates are designed for organizations that actively use their logo publicly but do not yet own a registered trademark.
To qualify for a CMC, the logo usually must:
- remain publicly visible,
- stay unchanged,
- and show more than 12 consecutive months of continuous usage history.
Logo history is typically reviewed through sources such as web.archive.org. CMC certificates support verified logo display in supported inboxes, although Gmail’s blue verified checkmark remains exclusive to VMC certificates.
