# Delete a Contact Identifier

## Operation overview

```json
{"path":"https://api.sendgrid.com/v3/marketing/contacts/{contact_id}/identifiers","method":"delete","servers":[{"url":"https://api.sendgrid.com","description":"The Twilio SendGrid v3 API"}]}
```

**This endpoint can be used to delete one identifier from a contact.**

Deletion jobs are processed asynchronously.

Note this is different from deleting a contact. If the contact has only one identifier, the asynchronous request will fail. All contacts are required to have at least one identifier.

The request body field `identifier_type` must have a valid value of "EMAIL", "PHONENUMBERID", "EXTERNALID", or "ANONYMOUSID".
