Address Validation API

In the world of payroll, address validity is incredibly important to determine appropriate taxation. In the past, we only validated addresses upon creation of specific entities, like workplaces. We’ve now rolled out a dedicated address validation endpoint so you can check any address against the USPS database to ensure they are accurate and can be used in Check. If you created an address somewhere else in your platform, you can use this endpoint to determine if it will work in Check before creating a workplace, company, employee or contractor. Note that this feature is offered at no additional charge for now; Check may update the fee structure in the future. Read more about address validation in our guide here.
