# contactIdentifier

The identifier for the contact associated with the person.

```
var contactIdentifier: String? { get set }
```

## Discussion

When you use the contact’s <doc://com.apple.documentation/documentation/Contacts/CNContact/identifier> value for the optional [`contactIdentifier`](/documentation/CoreSpotlight/CSPerson/contactIdentifier) property, it enables a direct way to look up the associated contact.
