iDenfy is a Lithuania-based identity and age verification platform founded in 2017, recognised in independent analyst evaluations of identity verification. The platform delivers document scanning, facial recognition, and liveness detection through an AI pipeline with high stated accuracy, supporting over 14,000 document types from 200+ countries. It is used by adult content platforms to satisfy compliance obligations under the UK Online Safety Act, EU rules, and the wave of US state-level age verification statutes that took effect across 2024-2025.

Integration is via SDK or API, allowing the verification flow to be embedded in existing onboarding UX rather than redirecting users to an external site. Pricing is per-check rather than subscription-based, which suits platforms where a fraction of sessions trigger full document verification. iDenfy has published specific guidance for adult-industry compliance use cases, demonstrating active engagement with the sector's regulatory requirements.

A technically strong, compliance-focused option for adult sites that need defensible, documented age verification with solid international ID coverage and proven adult-vertical experience.
