The ANSI National Accreditation Board (ANAB) is the United States' largest accreditation body, responsible for accrediting organizations involved in testing, calibration, certification, and inspection services. As a wholly owned subsidiary of the American National Standards Institute (ANSI), ANAB operates to ensure that conformity assessment bodies in the U.S. meet rigorous international standards of competence and reliability. Its primary mission is to enhance trust and confidence in the quality and performance of goods and services across various industries.

ANAB collaborates with a range of national and international organizations to uphold high standards of accreditation. It is a full member of the International Laboratory Accreditation Cooperation (ILAC) and the International Accreditation Forum (IAF). Through these memberships, ANAB participates in mutual recognition arrangements that facilitate the global acceptance of test and calibration results, certifications, and inspection reports issued by accredited U.S. bodies. These international partnerships help reduce technical barriers to trade and enhance the global competitiveness of U.S. products and services.

To maintain its leadership in accreditation, ANAB continuously updates its accreditation criteria and processes to align with international best practices. It provides essential services, including the accreditation of laboratories, certification bodies, and inspection agencies. By ensuring the quality and reliability of these services, ANAB supports regulatory compliance, consumer protection, and industrial innovation.
