# Checks

Every person and contract can interact with VePassport to check if an address can be considered a person. Additionally, modules can be called separately, allowing a certain amount of flexibility to implement custom personhood checks.

In the following pages, you can browse each module's endpoints and learn how the VePassport personhood check is performed.

The up-to-date interface of the VePassport contract can be found [here](https://docs.vebetterdao.org/vebetter/vebetter).
