International Organization for Standardization (ISO) certifications are globally recognized standards that ensure quality, safety, efficiency, and reliability in products and services. Organizations across the world adopt ISO standards to improve operational efficiency, build customer trust, comply with regulations, and enhance business credibility.
ISO itself does not issue certificates directly. Instead, accredited certification bodies audit organizations and provide certification after verifying compliance with specific ISO standards.
Currently, there are 24,000+ ISO standards, but only some are widely used for certification purposes in businesses and industries.
