What is DIATF / Digital Verification Services (DVS)?

The UK Digital Identity and Attributes Trust Framework (DIATF) is the government's certification scheme for organisations that provide or rely upon digital identity verification. Organisations that achieve certification are listed on the official Digital Verification Services (DVS) register; a signal to customers, partners, and regulators that their identity processes meet a rigorous, independently audited standard. For sectors such as financial services, recruitment, property, and professional services, where right-to-work, anti-money laundering, and know-your-customer checks are daily business, DVS certification is rapidly moving from competitive differentiator to baseline expectation. Inform-ISO guides organisations through the full certification journey: from readiness assessment and gap analysis, through policy and process alignment, to audit preparation and submission. Whether you are building a digital identity product or embedding compliant verification into your existing workflows, we provide the structured, expert support to get you on the register, and keep you there.
