# UserInfo Claim Structure

The table below provides descriptions of the attributes included in the `UserInfo` claim of the ID Token. The value of the `UserInfo` claim is a JSON object, and it is a **mandatory** attribute in all Corppass ID Tokens.

{% hint style="info" %}
**Mandatory Attributes**: These attributes will always be present in the `UserInfo` object and will always contain a value, which could be a blank string if no data is available.

**Non-Mandatory Attributes**: These attributes will only be included in the `UserInfo` object if data is available and they are not required by the schema.
{% endhint %}

The table below provides a detailed description of each attribute in the `UserInfo` claim of the ID Token.
