If you can't add your driver's license or state ID

• If there's a problem adding your driver's license or service is temporarily unavailable, try again later or contact your state issuing authority. Learn how to check if you're experiencing an Apple service outage.
• If your driver's license can't be added, contact your state issuing authority.
• If your driver's license can't be added because it's already associated with a different Apple ID or added on another iPhone, you need to remove your license or ID from the other Apple ID or iPhone. You also need to remove your license or ID from your paired Apple Watch before you can add it to a new iPhone.
