Hi there,

Thank you for the report!

I was checking further this issue, and I understand that you want to know if the space on the zip could be related to the validation error.

It wouldn’t make a lot of sense from what I see, as it is a basic validation on both sides.

In this case, I suppose that it might be because the zip associated with the card and the one provided on the checkout might not be matching.

You can see more about that here: https://stripe.com/docs/radar/rules/reference#post-authorization-attributes

I recommend you ask them to contact the card issuer and ask your customer to make sure that it is the same zip added there.

Hi Felipe,

thank you for the answer, sadly we did already all those checks with Stripe and the client and from their side they confirm that all is fine apart the ZIP that should be split in 2 parts with a space in the middle, this actually is the only thing i can think of.

Here you can see how it is passed in the API: https://drive.google.com/file/d/1yk3t9BphxnoQsS-3ymjNXsoa7Z6aqXLz/view?usp=drivesdk

Is there maybe a filter I can apply for testing purpose where I can intercept this specific ZIP and pass it into the API with a space?

Thanks

Hi there @pecoramannaraweb,

I tested this exact scenario and couldn’t reproduce the problem using the post code S0G0H0. I entered it without a space at checkout, and the WooCommerce Stripe extension passed it as a string with the space included:

It also was received by Stripe with the space:

I noticed in your screenshot that the postal code without the space appears in the Owner properties, which is not a value the WooCommerce Stripe extension sends in payment requests. Is the customer’s billing address somehow set like that in the Stripe dashboard?

Hey Tijosh, thanks for the answer, you make a good point with the “owner” properties, however we didn’t entered it. I assumed it came from the transactions and then Stripe saved it?

But as the client is also a developer and use regularly Stripe, he himself integrated it directly at the checkout of other sites (not using woocommerce integrations but the stripe checkout directly), and he keep saying he has never had this problem before in years, so I will keep investigating the issue more, hopefully something comes up.

Thanks

BTW, I tested it adding the space in the ZIP and I can confirm that same to me, I get it separate in the API call and also I can say that other clients are using it separate and get passed correctly, so there is nothing filtering it before the API call.

Hi, @pecoramannaraweb!

This is interesting as I just came across a similar issue with another user using a different Canadian zip code. Can you clarify for us, is the error coming up just for this one user?

The reason I ask is that, with :address_zip_check: = 'fail', at least according to Stripe’s documentation, the block would be coming from the card issuer, i.e., the zip code provided by the customer at checkout does not match what their bank has on file. And if that’s the case, then it would be best that the customer take it up with their bank. Do you think this might be the case here?

Actually I did some more in depth investigation after this suggestion (should have done it before probably), I exported all the payments and dive into the data more in depth to properly understand the matter.

We have plenty of completed payments from Canada, and I notice that there is a variety of approach, as many use space in the middle, other are uppercase, lowercase, mixed case, etc.. and all passed the Zip validation, no matter how the zip was used.

Only 6 didn’t pass in the first attempt, but 4 of those using another Zip they passed with the same card, so I definitely suspect that in this specific case, there is a mismatch between the zip code used by the client and the one from the bank, I can’t see another way to solve the issue.

Thanks for the help!

Hey, @pecoramannaraweb!

Thanks for the help!

First, you’re most welcome!

Second, really impressive digging. Thank you too for taking the time to validate our theory and update us with your findings. That’s really helpful!
