      address = AddressField(on_delete=models.CASCADE)
      enabled = models.BooleanField(default=True, null=False)
      phone = PhoneNumberField(null=True)
      email = models.EmailField(null=True)
      web_site = models.TextField()
  </code></pre>
  
  <p>I have added this in my settings.py file ...</p>
  
  <pre><code>PHONENUMBER_DB_FORMAT="RFC3966"
  </code></pre>
  
  <p>However, when I submit my form using the following JSON ...</p>
  
  <pre><code>{

              "street_number": "222",
              "route": "1212",

  }
  </code></pre>
  
  <p>I get this error (a 400 response)  ...</p>
  
  <pre><code>{"phone":["The phone number entered is not valid."]}
  </code></pre>
  
  <p>How else can I configure my server to recognize my phone number format (or do I need to change the format)?</p>
