A.5.5 Contact with authorities
The organization is to set up and keep up working contact with the authorities that are relevant to it. Purpose (stated in ISO/IEC 27002:2022): ensures information security information flows properly between the organization and legal, regulatory and supervisory authorities. As an Annex A reference control, it is compared with the controls determined in risk treatment (6.1.3 c) and recorded in the Statement of Applicability as included or excluded, with the justification and implementation status (6.1.3 d); implementation guidance is ISO/IEC 27002:2022 5.5.

Clauses 4 to 10 are the management-system requirements: none of them can be excluded when an organisation claims conformity. The 93 Annex A controls are a reference set: one may be excluded with a justification in the Statement of Applicability. Certification bodies assess conformity; the evidence lists here are what auditors commonly ask for, not a list the standard prescribes.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Common gaps auditors find
- Contact details are stale or held only by one individual
- No defined decision point or owner for notifying a regulator, so notifications miss statutory deadlines
- Utilities and emergency services are omitted from the continuity contact list
- Regulatory horizon scanning is not linked to the authority relationships
