International Accreditation Service

What International Accreditation Service does

International Accreditation Service (IAS) is an independent, nonprofit accreditation body founded in 1975 and headquartered in Brea, California. Operating as a wholly-owned subsidiary of the International Code Council (ICC), IAS evaluates and accredits conformity assessment bodies against internationally recognized standards, including ISO/IEC 17011, 17025, 17020, 17021-1, 17024, and 17065, as well as proprietary AC-series criteria (AC472, AC478, AC473, AC89, AC204, AC98, AC291, AC370, AC780, AC785, AC784, AC800, and others). Its portfolio spans 36+ accreditation programs serving testing laboratories, calibration laboratories, inspection agencies, certification bodies, medical laboratories, biobanking facilities, proficiency testing providers, reference material producers, building departments, metal building fabricators and assemblers, and government-focused environmental and food safety laboratories. IAS is recognized by federal agencies including the FDA (FSMA, ASCA, LAAF), EPA (ELAP, NLLAP), DoD (DoD ELAP), DoE (DoE CAP), NRC, CPSC, and FAA, and holds memberships in ILAC, IAF, IAAC, and APAC.

The organization generates revenue through non-refundable application fees, assessment fees, annual maintenance fees, and expansion-of-scope fees, supplemented by paid training services. Pricing is quote-based with annual billing cadence. Distribution is conducted through the IAS Portal web platform (application, document management, invoicing) and the IAS Connect mobile application (assessor workflows with offline sync), complemented by direct consultative engagement with applicants and onsite assessments by IAS-trained assessors. Marketing leverages the IAS website, peer-reviewed publications (International Journal of Conformity Assessment), social channels, webinars, and industry partnerships (MBCEA, MBMA). The company maintains a global footprint across 16+ countries spanning North America, Asia Pacific, the Middle East, Latin America, Europe, South Asia, and Africa, and recently launched the Global Accreditation Cooperation Incorporated alongside its 50th anniversary milestone in 2025.

Direct peers

• ANSI National Accreditation Board (ANAB): ANAB is a US-based accreditation body offering programs for testing/calibration labs, inspection bodies, certification bodies, and personnel certification — directly overlapping IAS's core ISO/IEC 17025, 17020, 17021-1, and 17024 offerings.
• American Association for Laboratory Accreditation (A2LA): A2LA accredits testing and calibration laboratories to ISO/IEC 17025 and inspection bodies to ISO/IEC 17020 — the same core laboratory-accreditation programs that anchor IAS's portfolio.
• Perry Johnson Registrars / Perry Johnson Laboratory Accreditation (PJLA): PJLA provides ISO/IEC 17025 laboratory accreditation and ISO/IEC 17020 inspection body accreditation, competing head-to-head with IAS in the US conformity-assessment market.

Broad incumbents

• NIST National Voluntary Laboratory Accreditation Program (NVLAP): NVLAP is a US federal government accreditation body that accredits testing and calibration laboratories across many of the same scopes as IAS, providing government-operated competition and a benchmark for laboratory accreditation.

Regional players

• United Kingdom Accreditation Service (UKAS): UKAS is the national accreditation body of the UK and an ILAC MRA signatory offering ISO/IEC 17025, 17020, 17065, and 17021-1 programs — operationally comparable to IAS but serving a UK/Europe customer base.
• Deutsche Akkreditierungsstelle (DAkkS): DAkkS is Germany's national accreditation body offering ISO/IEC 17025 and related accreditation programs; comparable to IAS in scope and global recognition, but focused on the German and broader European market.
• National Association of Testing Authorities (NATA), Australia: NATA is Australia's peak accreditation body for testing, calibration, inspection, and reference-material producers — directly comparable to IAS's laboratory and inspection accreditation programs but serving the Australia/New Zealand region.
• China National Accreditation Service for Conformity Assessment (CNAS): CNAS is China's national accreditation body providing ISO/IEC 17025 and ISO/IEC 17020 accreditation, competing with IAS for multinational accredited-customer footprints in China and Asia.

Others

• International Laboratory Accreditation Cooperation (ILAC): ILAC is the global cooperation of laboratory and inspection accreditation bodies of which IAS is a member; it sets mutual-recognition rules that underpin the value of IAS accreditation internationally, making it an ecosystem peer rather than a direct competitor.
• International Accreditation Forum (IAF): IAF is the worldwide association of accreditation bodies for management systems, products, services, and personnel certification; IAS holds IAF membership, and IAF MLA signatory status is a key enabler of the global acceptance of IAS-accredited certifications.
