# subscriptionID

The subscription’s unique identifier.

## Declaration

```occ
@property (copy, readonly) CKSubscriptionID subscriptionID;
```

## Discussion

Discussion This property’s value is the subscription ID that you provide to the initWithRecordType:predicate:subscriptionID:options: or initWithZoneID:subscriptionID:options: methods when you create the subscription. If you use a different method to create the subscription, CloudKit automatically assigns a UUID as the subscription ID.
