Use restrictions and guidelines
ISO logo
Do not use, copy, modify, or alter the ISO logo.
The ISO logo cannot be used in any advertising, marketing materials, websites, or social media unless you are an ISO member or technical committee.
Certification bodies provide their own certification logos; companies certified to ISO standards should use the certification body’s logo, not the ISO logo.
ISO short name "ISO"
Avoid using "ISO" in domain names, company names, product or service names.
Do not suggest or imply that your company, product, or service is endorsed, approved, or certified by ISO.
When referring to ISO standards, always use the full reference such as "ISO 9001:2015."
Why follow these rules?
ISO represents quality, trust, safety, and confidence worldwide.
Misuse of the ISO trademarks can mislead customers and damage ISO’s reputation.
ISO and its members will take legal action against unauthorized or misleading use of their trademarks, including trademark enforcement and takedown requests.
How to use ISO branding correctly
Refer to ISO by its full name or by the correct standard number.
Use certification logos provided by accredited certification bodies, not the ISO logo.
