What is an Identity Service Provider (IDSP)?

Understanding the role of Identity Service Providers in the UK DVS trust framework, whether you're consuming digital identities or looking to certify as an IDSP.

Certification as an IDSP

An Identity Service Provider (IDSP) is a specific role within the UK DVS trust framework that performs identity verification services. Here's what defines an IDSP:

One-off verification

An IDSP checks a user's identity for single-point-in-time use, providing verification services across relationships between users, businesses, and government.

Specialist or integrated

IDSPs can specialise purely in identity checking or offer it alongside other services (e.g., banks, solicitors, libraries, postal organisations).

Overall responsibility

While an IDSP doesn't need to perform every step of the identity checking process itself, it remains responsible for the overall process and outcome, including any third-party components.

Multiple roles possible

If an IDSP also creates or shares attributes (e.g., digital credentials), it's also an Attribute Service Provider. If it holds and supports reuse of digital identities, it's also a Holder Service Provider.

If you're consuming digital identities

As a relying party, an IDSP that appears on the DVS register provides you with independently certified, trustworthy identity verification services that meet government standards for security, privacy, and reliability.

Trusted identity verification

IDSPs on the DVS register have been independently certified to meet government standards for secure, reliable identity checking.

Compliance assurance

Use certified IDSPs to meet regulatory requirements for identity verification in areas like right to work, right to rent, and DBS checks.

Reduced risk

Certified IDSPs follow strict operational, security, and privacy standards, reducing your exposure to fraud and data breaches.
