Format facts

    IAM unique-ID prefix table: AKIA/ASIA/ABIA/ACCA prefixes, and AIDA as the IAM-user unique-ID prefix rather than an access key (re-checked 2026-09-20, #36); 16-character base32 body and 40-character secret are tool-corroborated

Benchmark dossier notes

From the provider dossier, as written. The evidence level above says how well the format is backed; a fact the dossier does not record is not shown.
Shape
Long-term access key ID for an IAM user, prefixed AKIA.
Basis
T1 per the shipped aws-access-key contract in the benchmarks assessment: the IAM unique-identifier prefix table documents the AKIA prefix. The 16-character base32 body and the 40-character companion secret are tool-corroborated, not provider-stated. Provider source re-checked 2026-09-20 in benchmarks#36 (PR #38). The contract does not cover ASIA.
