Choose which user attributes your service can request

Your service can request certain user attributes. To do this, you need to choose which ‘scopes’ or ‘claims’ your service will use and include these when you make your authorisation request.

OpenID Connect (OIDC) scopes are identifiers your application uses during authentication to authorise access to a user’s attributes, such as an email address. Each scope returns a set of user attributes contained within it. OIDC calls this set of user attributes ‘claims’.

The user attributes and how you request them will depend on whether you are requesting authentication only, or authentication with identity assurance.

Type of request you’re making What type of user attributes you can request
Authentication only You can only request user attributes using scopes.
Authentication and P1 identity assurance You can only request user attributes using scopes.
Authentication and P2 (or higher) identity assurance You can request user attributes using both claims and scopes (or either claims or scopes, depending on what your service needs).

You’ll need to agree which scopes and claims you want to use when you register your service to use GOV.UK Sign In.

Choose which scopes your service can request

openid is the only scope you must include. You can choose to include other scopes for your authorisation request depending on the user attributes your service needs.

You can find details of the scopes in the following table.


Required or optional




OIDC authorisation requests must contain the openid scope value to indicate that an application intends to use the OIDC protocol.

This will return the sub claim, which uniquely identifies your user.



Returns the email claim, which contains:

  • your user’s email address
  • email_verified, which is a boolean indicating whether your user has verified their email address or not



Returns the phone_number claim, which contains:

  • your user’s phone number
  • phone_number_verified, which is a boolean indicating whether your user has verified their phone number or not



You use an access token to make calls to the /userinfo endpoint.
If you want to access the /userinfo endpoint for longer than 3 minutes, you should use a refresh token to refresh your access token.
If you want a refresh token, you must request the offline_access scope.

Choose which claims your service can request

You can also request specific claims from GOV.UK Sign In, if you need more information than the scopes in the previous section can provide. You must choose a level of identity confidence P2 or above, otherwise you will not receive any claims in the authorisation response.

You can find details of the claims in the following table.

Claim Description This claim contains core identity information about your user:
  • their names
  • their date of birth
  • the level of confidence GOV.UK Sign In reached in your user’s identity This claim contains your user’s postal addresses. This claim contains your user’s passport details if GOV.UK Sign In proved their identity using their passport.

If GOV.UK Sign In did not prove your user’s identity using their passport, the authorisation response will not return this claim.

You can see more about the structure of this information when you process your user’s identity information.

You can only ask us for claims that are covered by your Data Protection Impact Assessment. You must clearly explain to your users why you are collecting the data and what you will use it for.

Once you have chosen which attributes your service can request, you can manage your service’s configuration with GOV.UK Sign In.
