# Addon

## Do I need a separate license for each addon?

Yes—each add-on requires its own license. See pricing at <a href="https://www.dynamsoft.com/store/dynamic-web-twain/" target="_blank">Dynamic Web TWAIN Pricing</a> and the licensing guide at [Using License Keys](/_articles/general-usage/license.md){:target="_blank"}.

For per-client-device licenses, you can add an add-on license to the existing project without changing the license key string in your application. Organization ID/handshake details are in the Dynamsoft License Server terms <a href="https://www.dynamsoft.com/license-server/docs/about/terms.html#organization-id" target="_blank">here</a>.
