As a provider of ISO 17025 accredited calibration services we often receive terms and conditions that require a conversation with our clients. A common conversation is the term: "calibrate to A2LA". In discussions with clients that make this request it becomes clear what they really want is ISO 17025 accredited calibration.
What is the difference between A2LA, ANAB, L-A-B and ISO 17025?
A2LA is an acronym for American Association for Laboratory Accreditation. It was started in 1978 and operates as a 501(c)3 non profit organization. Source:https://www.a2la.org/about

ANAB is NOT a standard. They are a 3rd party accreditation body.
ISO 17025 is the internationally recognized standard for calibration. If you want an accredited calibration you need to specify ISO 17025 not A2LA, L-A-B or ANAB.
The role of the international bodies mentioned above is to ensure that 3rd Party accreditation bodies provide unbiased and objective evaluations of calibration services. Yes, 3rd Party accreditation services are audited by international bodies for conformance.
NCSL International has an excellent resource explaining the benefits of accredited calibration.
