Remove the Postal Code Requirement


If the country code for the targeted location is the United States (US), Canada (CA), or the United Kingdom (GB), you must not remove the postal code requirement. Doing so results in all credit card transactions being declined.

The postal code requirement can be removed for all other countries.

Requirements and limitations

  • You have integrated the In-App Payments SDK into your iOS or Android application.
  • Your application can get the location country code of the seller who is taking the payment. This must be done by your server backend using the Locations API, because the payment is taken on the buyer's mobile device.
  • Your application is based in a country that doesn't require the postal code for processing payments.

1. Get the location country of the seller

Your mobile application needs to make a request to your server backend to get the correct location and location country. To be valid, the target location must have ACTIVE status and CREDIT_CARD_PROCESSING enabled and the field cannot be US, CA, or GB.

Follow the steps in Locations API to find the correct location.
