# objectID

The object ID of the managed object.

```
var objectID: NSManagedObjectID { get }
```

## Discussion

If the receiver is a fault, accessing this property does not cause it to fire.

> Important:
> If the receiver has not yet been saved, the object ID is a temporary value that will change when the object is saved.

## See Also

[`-  URIRepresentation`](/documentation/CoreData/NSManagedObjectID/uriRepresentation())
