## Share PIN with the cardholder

To share the PIN with the cardholder, you can do one of the following:

- Ship the PIN to the cardholder, in a separate letter to the card itself.
- Integrate with the [Android](https://www.checkout.com/docs/developer-resources/sdks/card-issuing-sdks/card-management-android-sdk.md) or [iOS](https://www.checkout.com/docs/developer-resources/sdks/card-issuing-sdks/card-management-ios-sdk.md) Card Management SDK to enable the cardholder to access the PIN in your mobile app.

> **Information**
>
> We recommend confirming with the cardholder that they have received their card and PIN and ensuring that the card is [activated](https://www.checkout.com/docs/card-issuing/activate-a-card.md).
