# Removes postal code for card payments in certain regions on Checkout and Payment Element

## What’s new

A postal code is no longer collected for all card payments on [Checkout](https://docs.stripe.com/payments/checkout.md) and [Payment Element](https://docs.stripe.com/payments/payment-element.md) in the following regions:

- Canada
- United Kingdom
- Puerto Rico

## Why is this a breaking change?

Previously, the postal code was always collected for card payments in the following scenarios:

- On Checkout when [billing_address_collection](https://docs.stripe.com/api/checkout/sessions/create.md?api-version=2025-09-30.clover#create_checkout_session-billing_address_collection) was set to `auto`.

- On Payment Element when [billingDetails.address](https://docs.stripe.com/js/elements_object/create_payment_element#payment_element_create-options-fields-billingDetails-address) was set to `auto`.

## Impact

If you currently rely on the postal code for customers in the affected regions and don’t have [automatic_tax](https://docs.stripe.com/api/checkout/sessions/object.md?api-version=2025-09-30.clover#checkout_session_object-automatic_tax) enabled, make the changes necessary to collect this field manually:

- For [Checkout Sessions](https://docs.stripe.com/api/checkout/sessions.md?api-version=2025-09-30.clover), you can set [billing_address_collection](https://docs.stripe.com/api/checkout/sessions/create.md?api-version=2025-09-30.clover#create_checkout_session-billing_address_collection) to `required`. However, this will collect the full billing address and affect other payment methods and regions.

- For Payment Element, you need to add your own custom fields for country and postal code, as well as set [billingDetails.address](https://docs.stripe.com/js/elements_object/create_payment_element#payment_element_create-options-fields-billingDetails-address) to `never`.
