Hello 👋

#

there's no validation on the front-end

#

AFAIK

#

there's only formatting

dapper sleet Oct 12, 2023, 12:31 PM

#

but there is validation of the US postal code

#

I've seen that there is an issue at Stripe about that inanother request in this channel

Hi! I'm taking over this thread.

#

Can you really type any number and it works? Like a single digit or letter for example?

#

Usually we do some basic checks on the frontend (like number of characters).
Then once the payment is sent to the card network, there will be an AVS Check. You can learn more about this here: https://stripe.com/docs/disputes/prevention/verification

Actually it looks like it's a known issue that we don't validate the format of UK postal code. Sorry about this.

dapper sleet Oct 12, 2023, 12:49 PM

#

if there any solution to made our own validation of the input ?

Stepping in as soma needs to step away

#

No there isn't a way to perform validation currently on a UK postal code until after the PaymentMethod has been created

#

So you could use the two step flow like with https://stripe.com/docs/payments/build-a-two-step-confirmation if you want to validate that way
