What is an ISO Certificate?

An ISO (International Organization for Standardization) certificate signifies that an organization adheres to internationally recognized standards in areas such as quality management, environmental management, and information security. It assures clients, customers, and stakeholders that a business consistently meets high standards.

Why is Verifying an ISO Certificate Important?

Before engaging with a company, it is crucial to verify whether its ISO certification is genuine and up-to-date. A valid ISO certificate:

• Guarantees that the company follows quality practices
• Protects your business from risks related to subpar goods or services
• Enhances your credibility by partnering with certified organizations
• Ensures legal and regulatory compliance

Steps to Verify an ISO Certificate

Here’s a simple process to ensure that an ISO certificate is valid –

Review the Certificate Details

The first step in verifying an ISO certificate is to check the basic details on the certificate itself:

• Certification body: The organization that issued the certificate should be listed clearly. This should be a recognized and accredited certifying body.
• Certificate number: The certificate should have a unique certificate number that can be tracked.
• Scope of certification: This outlines the areas for which the business is certified.
• Expiration date: Check the validity period of the certification. ISO certificates are typically valid for 3 years, after which they must be renewed.

Verify the Issuing Certification Body

Not all ISO certificates are equal. Some organizations issue certificates that may not be from accredited certification bodies. To confirm that the certificate is legitimate, you should:

• Look up the certifying body: Verify if the organization that issued the certificate is accredited by a recognized body, such as the International Accreditation Forum (IAF) or the ANSI National Accreditation Board (ANAB).
• Check the certification body’s website: Most accredited bodies have online databases where you can look up the certificate number or search for the company’s details.

Contact the Certification Body

Once you have the name of the certification body, it’s best to contact them directly for verification. You can do this by visiting the certification body’s official website or calling their office.

• Provide the certificate number: When contacting the certifying body, share the certificate number, the organization’s name, and other details provided on the certificate.
• Ask for verification: Ask if the organization is currently certified under the relevant ISO standard and if the certificate is valid.

Most certification bodies have a verification process that allows you to confirm whether a business holds a valid and current ISO certification.

Check the Accreditation Status Online

Many recognized certification bodies offer online verification tools. You can visit their websites and use these tools to search for companies that have been certified by them. Examples of such organizations with online databases include:

• International Accreditation Forum (IAF): Offers a global directory of accredited organizations.
• UKAS: The United Kingdom Accreditation Service allows you to verify certificates issued by UK-based accreditation bodies.
• ANAB: Provides an online database for organizations accredited by ANSI.

Confirm Renewal and Surveillance Audits

ISO certifications are not one-time achievements; they require regular surveillance audits to ensure the company continues to meet standards. A genuine ISO certification should be backed by:

• Periodic audits: Companies are subject to regular surveillance audits, usually every 6 months or 12 months, depending on the certification type.
• Renewal: ISO certificates need to be renewed after 3 years, and the organization should undergo re-certification audits.

You can ask the company to share their audit reports or renewal certificates to verify if they are compliant with ongoing ISO standards.

Be Wary of Fake Certificates

Be cautious of fake or misleading ISO certificates. Common signs that a certificate may not be genuine include:

• Missing accreditation details or logos of certification bodies
• Vague or incomplete information
• Unclear or incorrect company details
• Certificate issued by an unknown, non-accredited body
• A lack of renewal or surveillance audit history

Use Third-Party Verification Services

In some cases, third-party verification services can be used to cross-check the legitimacy of an ISO certificate. These services often charge a fee but offer detailed verification, helping you avoid fraudulent or outdated certificates.
