Step 1
Define the decision
Your service sends who is asking, what they need, which policy version applies, and channel context. The format is the same for live API calls and offline packets.
What is stateless eligibility verification for UK government?
Stateless eligibility infrastructure for departments, agencies, and regulated bodies.
Short answer: After sign-in (for example GOV.UK One Login), programmes still need allow or deny answers with proof - not another citizen data silo. AffixIO returns signed yes/no outcomes via API and SDK and does not retain request payloads.

Verification for UK government programmes
AffixIO provides stateless eligibility infrastructure for departments, agencies, and arm's-length bodies. Your services receive a clear yes or no with cryptographic proof, without building another citizen data store at the verification layer.

View sector pageFrom request to verified outcome
The same three-step model used across AffixIO applies here: describe the decision, evaluate against sources you control, return yes or no with proof.
Step 2
Evaluate against authority
Checks run against registries and rules you authorise. Sensitive fields stay in systems you already operate wherever the design allows.
Step 3
Return yes or no with proof
The response is explicit, signed where required, and suitable for audit or partner handoff. AffixIO does not retain the request after the decision.
Where AffixIO sits in your stack
A thin stateless layer between citizen channels and core departmental systems. It answers eligibility questions; it does not replace case management, payments, or identity providers.

Capabilities used across government programmes
Binary eligibility
One verified decision for benefits, access, pricing, and similar rules. Documented on the eligibility API page.
Identity without retention
Confirm facts via API without storing PII at AffixIO. See identity product and government database integration.
Physical and digital access
Gates, accounts, and field checkpoints with evidence security teams can cite. Access control use cases.
Agentic and automated channels
Machine clients receive the same signals as human channels. Machine-to-machine verification.
Cryptography and data handling
Built for long-lived programmes that must plan beyond legacy signatures and minimise data held at the verification boundary.
Stateless by design
No long-term store of who asked or the attributes inside a request. Supports proportionate DPIA narratives.
ML-DSA ready
Artefacts can use Module-Lattice-Based Digital Signature Algorithm (ML-DSA), aligned with NIST post-quantum direction, with optional HSM-backed key ceremonies.
Zero-knowledge outcomes
Where policy allows, demonstrate that a rule evaluated to yes without exporting underlying registry content.

Common questions
How does AffixIO relate to GOV.UK One Login?
One Login and certified identity services handle authentication. AffixIO answers eligibility after that step - benefits, tax, right to work, licensing - with stateless decisions and signed proof.
Which UK departments can use this pattern?
HMRC, DWP, DVLA, NHS, Home Office, MOD, TV Licensing, councils, and digital-identity relying services. Each sector page describes typical use cases and integration posture.
Does AffixIO store citizen personal data?
No. AffixIO is stateless verification infrastructure. It evaluates a request against sources you authorise and returns a decision with proof.
Can this run offline for field teams?
Yes. Signed proofs can be validated where connectivity is limited, with reconciliation when back online.
