Title: Error: Billing Postcode / ZIP is not a valid postcode / ZIP Last modified: June 3, 2020 --- # Error: Billing Postcode / ZIP is not a valid postcode / ZIP * Resolved [Patrick](https://wordpress.org/support/users/pmdigital/) * (@pmdigital) * [6 years ago](https://wordpress.org/support/topic/error-billing-postcode-zip-is-not-a-valid-postcode-zip/) * Hello, In the checkout page when selecting Portugal as a country and leave the other address fields empty (as there are optional) it shows the following message when submitting the form: Billing Postcode / ZIP is not a valid postcode / ZIP. * I tried with UK and it doesn’t show any message. The plugin is up to date (Version 3.8.1) * Are there any settings I’m supposed to change? Thank you Viewing 4 replies - 1 through 4 (of 4 total) * Plugin Support [Tseten a11n](https://wordpress.org/support/users/tibetanitech/) * (@tibetanitech) * [6 years ago](https://wordpress.org/support/topic/error-billing-postcode-zip-is-not-a-valid-postcode-zip/#post-12932155) * If I understand it correctly, you are trying to checkout on your site where you would like to leave the billing postcode blank. You mentioned you can checkout with the country as UK with blank postcode however if you use the country as Portugal, you cannot checkout with blank postcode – correct? * Could you please share a copy of your site’s System Status to understand how your site is configured? You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”.  Once you’ve done that, paste it here in your response. * Thread Starter [Patrick](https://wordpress.org/support/users/pmdigital/) *

To figure out which plugin is causing the problem, reactivate your other plugins one by one, testing after each, until you find the one causing conflict. You can find a more detailed explanation on how to do a conflict test here. * Plugin Support [Tseten a11n](https://wordpress.org/support/users/tibetanitech/) * (@tibetanitech) * [6 years ago](https://wordpress.org/support/topic/error-billing-postcode-zip-is-not-a-valid-postcode-zip/#post-12969373) * We haven’t heard back from you in a while, so I’m going to mark this as resolved– if you have any further questions, you can start a new thread.
