Identity verification that respects privacy.
Provn is a unified identity verification platform for businesses and individuals. Verify NIN, BVN, CAC records, addresses, and more through a single API—without ever storing your customers' personal data.
Identity verification is broken.
Fragmented identity databases
Your customers are spread across multiple identity databases. NIN here. BVN there. CAC somewhere else. Each one requires a different integration, a different vendor, a different compliance headache.
Unwanted PII liability
You're forced to collect and store sensitive personal data you never wanted — creating liability with every record.
AI-powered identity fraud
AI-generated synthetic identities, deepfakes, and fabricated documents are growing faster than traditional verification can handle.
One API. Every verification.
Zero PII stored.
Provn connects you to Nigeria's identity databases through a single integration. Verify customers in seconds. Receive yes/no attestations and risk scores—never raw personal data.
Unified verification
NIN, BVN, CAC, address, phone, and sanctions screening. One endpoint.
Privacy by default
Your systems never touch PII. Provn handles the data; you get the answer.
Continuous monitoring
Not a one-time check. We re-verify when risk signals change and notify you instantly.
Compliance built in
NDPR-compliant by design. Audit trails, data residency controls, and regulatory reporting included.
What we're building
Provn Verify — KYC/KYB API
LiveUnified identity and business verification. NIN, BVN, CAC, address, phone, sanctions and PEP screening, continuous monitoring.
Provn Passport — Identity Wallet
BuildingA mobile wallet that gives individuals control over their identity. Share only what's needed using zero-knowledge proofs. Revoke access anytime.
Provn Guardian — AI Identity Agent
Coming SoonAn autonomous agent that monitors your identity across the web. Dark web scanning, breach alerts, SIM swap detection, automatic access revocation.
Provn Auth — SSO & Authentication
Coming SoonPasswordless, ZKP-based single sign-on with FIDO2 passkey support. Prove who you are without transmitting credentials.

Built on serious cryptography
Provn is not just another API wrapper. We're building identity infrastructure on zero-knowledge proofs, homomorphic encryption, and trusted execution environments—so that verification never requires exposing sensitive data.
Zero-Knowledge Proofs
Verify claims without seeing the underlying data. BBS+ signatures enable selective disclosure by default.
Homomorphic Encryption
Run verification checks on encrypted data. We return the result without ever seeing the plaintext.
Trusted Execution Environments
Sensitive operations run inside hardware enclaves. Not even our own infrastructure operators can access the data.
Trusted by leading institutions across Nigeria
