It depends on the country: https://stripe.com/docs/js/element/postal_code_formatting#:~:text=For instance%2C if a U.S. card is entered%2C the postal code field only accepts a five-digit numeric value. If it’s a UK card%2C an alphanumeric value can be provided instead.

#

so if someone uses a US card but inputs UK address like the example I'll get invalid postal code?

#

Thanks for your response btw!

#

I'm asking since we are getting live customer experience this issue so it doesn't seem like a test-only issue

#

No problem! That would depend on your radar settings. If you are blocking incorrect postal code. We have some test cards to test that scenario: https://stripe.com/docs/testing#fraud-prevention

Testing

Simulate payments to test your integration.

#

What issue are you seeing specifically?

cursive steeple Aug 9, 2022, 2:09 PM

#

we only get the first part of the postal code

#

so we can not ship

#

How do you collect shipping address? That should be separate from billing address

#

the image I sent describes the problem

#

when we do a payment request for googlePay. the postal code in GP is a two-part code.

#

yet on the payment request onShippingAddressChange we only get the first part of the postal code from your API

#

That's a canadian address though

cursive steeple Aug 9, 2022, 2:13 PM

#

yeah, happening on UK addresses aswell

#

all two-part postalcodes

stuck stirrup Aug 9, 2022, 2:14 PM

#

Gotcha. I know for billing in the US it's only a 5 digit postal code that's accepted. I'm not sure about shipping. Let me ask a colleague about this

cursive steeple Aug 9, 2022, 2:14 PM

#

seems odd you'd trim the postalcode and send an invalid one

#

yet on stripe dashboard, the postalcode is complete

stuck stirrup Aug 9, 2022, 2:15 PM

#

I'm not familiar with UK postal codes. Is the second part required?

#

In the US it's optional and you can still ship without it

#

Will check this with a colleague though

cursive steeple Aug 9, 2022, 2:15 PM

#

I presume it is. I have merchants complaining so I guess it's a problem for them

#

thanks for checking

stuck stirrup Aug 9, 2022, 2:20 PM

#

Ah my colleague got back. So the shipping address being trimmed is expected in the events before the payment is complete. See this section: https://stripe.com/docs/js/payment_request/events/on_shipping_address_change#payment_request_on_shipping_address_change-handler-shippingAddress

Stripe JS Reference

#

this means you can’t get the full address until after the customer authorises the payment and you’re handling that in the on('paymentmethod', function(ev){..}) stage( at which point ev.shippingAddress should exist and be complete)

#

gotcha. thanks for your help!
