IDDQD passes its 2026 ISO/IEC 27001 audit

IDDQD has passed its 2026 ISO/IEC 27001 audit. An independent certification body examined the group's information security management system and confirmed its certification to ISO/IEC 27001:2022 for another year.

ISO/IEC 27001 is the international standard for managing information security. A certified company has shown an auditor that it identifies its security risks, runs controls against them and reviews those controls as the risks change. The auditor returns every year to test that the controls operate in practice.

IDDQD has held the certificate since 2020. One certificate covers the whole group: the people, systems and processes behind Ideal Postcodes, AddressZen, Postcodes.io and Uprns.io.

For buyers, that shortens procurement. A single group-level certificate answers the security section of a supplier questionnaire, whichever IDDQD service they use. The current certificate is available to download, and IDDQD supplies further compliance documents on request.
