ISO's logo is not for use

Upon certification, many organizations turn to ISO to request use of "the ISO 9000 logo". No such ISO logo exists. There is only the ISO logo itself, which is a registered trademark. Unless authorized by ISO, use of its logo is prohibited. ISO will not allow its logo to be used in connection with the certification of management systems, even when these certifications attest conformity to ISO 9001:2000 (or ISO 9001:2008) or ISO 14001:2004.

Examples of unacceptable use of the ISO logo would include use on products, on Web sites, in marketing materials, advertisements and company letterheads.

Allowing the ISO logo to be used would give the false impression that ISO carries out certification activities, or has approved or authorized the organization using its logo. These activities are not business functions of ISO.
