title: Stripe card checks coming back null
body: <p>Using the Stripe.js V3 to create a a card element ...</p>
  <pre><code>var card = elements.create('card', {style: style, hidePostalCode: true});
  </code></pre>
  <p>Passing token to my Django backend where I am also building the payment method.</p>
  <pre><code>payment_method = stripe.PaymentMethod.create(
      type=&quot;card&quot;,
      card={
          &quot;token&quot;: request.POST['stripeToken']
      },
      billing_details= {
          &quot;address&quot;: {
              &quot;city&quot;: ...,
              &quot;country&quot;: 'US',
              &quot;line1&quot;: ...,
              &quot;line2&quot;: ...,
              &quot;postal_code&quot;: ...,
              &quot;state&quot;: ...,
          },
          &quot;email&quot;: ...,
          &quot;name&quot;: ...,
          &quot;phone&quot;: ...,
      },
  )
  </code></pre>
  <p>The response I'm getting from stripe.PaymentMethod.create(...)</p>
  <pre><code>&quot;checks&quot;: {
    &quot;address_line1_check&quot;: null,
    &quot;address_postal_code_check&quot;: null,
    &quot;cvc_check&quot;: &quot;pass&quot;
  },
  </code></pre>
  <p>Can I validate address_line1_check and address_postal_code_check on PaymentMethod?
  If not then what would be the best practice to tell if the card is valid before running payment?</p>
  <p>New to stripe sorry if this seems lengthy, thanks</p>
