Title: Getting an error: Billing postcode / zip is not a valid postcode. on Poland Last modified: April 26, 2024 --- # Getting an error: Billing postcode / zip is not a valid postcode. on Poland * Resolved [optimalprime](https://wordpress.org/support/users/optimalprime/) * (@optimalprime) * [2 years, 1 month ago](https://wordpress.org/support/topic/getting-an-error-billing-postcode-zip-is-not-a-valid-postcode-on-poland/) * Hello, * I have found out that the problem is on filling out the country “Poland” specifically. I will describe what happens. The woocommerce report doesnt show any fails and now error log report. * So when you start to fill out a booking on the link provided and you choose Poland as the client Country on the checkout screen when chosen European Bank transfer( the option on the bottom) it will give the error: * `Billing postcode / zip is not a valid postcode. ` * It will refuse to finish the order. If you then choose to alter it into another country on the same checkout page that you are still in, for example Netherlands, it will succesfully finish it. Made me think if Poland wasnt a Sepa country, but it is. So I have no idea why Poland gets this message specifically. Please can you test it for yourself and tell me what you think? Thank you. * ```wp-block-code ` WordPress Environment WC Version: 8.6.1 REST API Version: ✔ 8.6.1 WC Blocks Version: ✔ 11.8.0-dev Action Scheduler Version: ✔ 3.7.1 Log Directory Writable: ✔ WP Version: 6.5.2 WP Multisite: – WP Memory Limit: 1 GB WP Debug Mode: – WP Cron: – Language: en_GB External object cache: ✔ Server Environment Server Info: LiteSpeed PHP Version: 8.2.4 PHP Post Max Size: 100 MB PHP Time Limit: 30 PHP Max Input Vars: 3000 cURL Version: 7.87.0 OpenSSL/1.1.1p SUHOSIN Installed: – MySQL Version: 10.6.16-MariaDB-cll-lve Max Upload Size: 100 MB Default Timezone is UTC: ✔ fsockopen/cURL: ✔ SoapClient: ✔ DOMDocument: ✔ GZip: ✔ Multibyte String: ✔ Remote Post: ✔ Remote Get: ✔ Database WC Database Version: 8.6.1 Total Database Size: 46.27MB Database Data Size: 33.10MB Database Index Size: 13.17MB attachment: 458 custom_css: 1 customize_changeset: 1 gs_faq: 14 ml-slide: 5 ml-slider: 1 mphb_booking: 1153 mphb_coupon: 5 mphb_payment: 624 mphb_rate: 18 mphb_reserved_room: 1270 mphb_room: 17 mphb_room_attribute: 2 mphb_room_service: 12 mphb_room_type: 16 mphb_season: 16 nav_menu_item: 26 oembed_cache: 1 page: 34 popupbuilder: 9 post: 41 product: 1 revision: 467 shop_order: 511 simple_pricing_table: 1 testimonial: 4 wp_block: 4 wp_global_styles: 1 wp_navigation: 1 wpforms: 1 Security Secure connection (HTTPS): ✔ Hide errors from visitors: ✔ Active Plugins (30) advanced-cache.php: advanced-cache.php maintenance.php: maintenance.php object-cache.php: object-cache.php Must Use Plugins (1) aios-firewall-loader.php: by – Settings API Enabled: – Force SSL: – Currency: EUR (€) Currency Position: left Thousand Separator: , Decimal Separator: .

You choose to book. And on the booking screen thats follows you fill out adults: 1 * Then on “your information” you let the fields be autofilled by what it suggests and after change the country manually to for example Poland. Then you go to the next screen and Dont fill out anything. Especially not change or add anything in the address fields. Then choose European Bank Transfer and that should give you the error. * It should give the error. I used the chrome browser. * Thank you * [Zee](https://wordpress.org/support/users/doublezed2/) * (@doublezed2) * [2 years, 1 month ago](https://wordpress.org/support/topic/getting-an-error-billing-postcode-zip-is-not-a-valid-postcode-on-poland/#post-17722533) * Hello [optimalprime](https://wordpress.org/support/users/optimalprime/) * Thank you for your reply. * I followed your instructions and the result was the same as before. I did not encounter any issues. I am using Google Chrome. * Here is a [video recording](https://drive.google.com/file/d/1J5mK_jU5_RcWUL6zabEzd4U5vooFNL-6/view?usp=sharing) of my steps. Please let me know if you see anything odd. * I look forward to your reply. 🙂 * Best regards. * Thread Starter [optimalprime](https://wordpress.org/support/users/optimalprime/) * (@optimalprime) * [2 years, 1 month ago](https://wordpress.org/support/topic/getting-an-error-billing-postcode-zip-is-not-a-valid-postcode-on-poland/#post-17722998) * Thank you for investigating it. Maybe my directions were unclear, but after watching the video I do see some differences. The first difference I dont think is a problem, but most people on the booking screen fill in the fields on the far right column and click the blue “search” button. I dont think this will make a difference or is relevant for the postcode error though. * The thing I do think makes the difference is when you are on the screen where you fill out the amount of adults / kids I noticed that you filled out the “your information” fields manually. The 1st field is “first name” now many people when filling out there name will get autofill suggestions here. Once you click on the autofill suggestion it will fill out all other fields right away automatically, so name, country, phone and email. You manually filled it out instead. Can you please test this with choosing an autofill option on the “first name” field and after when all fields are filled out change the country field, that is prefilled then too, to another country manually and then after finish the process exactly how you did before (so not change anything on the checkout page and then choose European bank transfer). This will recreate the error, I had this recreated already with 4 different people. * Hope I am more clear now, thank you again. * [carolm29 (woo-hc)](https://wordpress.org/support/users/carolm29/) * (@carolm29) * [2 years, 1 month ago](https://wordpress.org/support/topic/getting-an-error-billing-postcode-zip-is-not-a-valid-postcode-on-poland/#post-17726450) * Hey, [@optimalprime](https://wordpress.org/support/users/optimalprime/)! * Thank you for the clarification, I did as you mentioned and I was able to see the issue with not only Poland, but also Portugal (I started trying other countries to check, and the third one I tried, New Zealand, went through). * I see on your report you have an outdated version of WooCommerce. * We recommend keeping everything updated. Regularly updating everything helps maintain your site’s security, performance, and compatibility while ensuring you benefit from the latest features and improvements. * So please update Woo, any other plugin that needs it, as well as your theme and check if the issue persists. * If it does, please add a simple product via the default WooCommerce interface and try it out. Please let us know if the issue also happens with simple products so we can assist you further. * Also, I don’t see the plugin list on your report, do you mind sharing it again with the plugin list so we can take a look? You can do it after updating everything so we see the current versions. * Looking forward to your reply. * Have a wonderful day! * [anastas10s](https://wordpress.org/support/users/anastas10s/) * (@anastas10s) * [2 years ago](https://wordpress.org/support/topic/getting-an-error-billing-postcode-zip-is-not-a-valid-postcode-on-poland/#post-17751209) * Howdy 👋 We haven’t heard back from you in a while, so I’m going to mark this as resolved – we’ll be here if and/or when you are ready to continue. * Thread Starter [optimalprime](https://wordpress.org/support/users/optimalprime/) * (@optimalprime) * [2 years ago](https://wordpress.org/support/topic/getting-an-error-billing-postcode-zip-is-not-a-valid-postcode-on-poland/#post-17751217) * Hello, I directly reacted in the mail, but guess that doesnt work. So my reaction here on your answer: * Ok,  * “so there might have been adjustments made to its validation rules.” * By who? If you mean me? Besides making it optional I did not. The technicality of it not working, I do agree it probably is one of these reasons. But if these adjustments weren’t applied universally will this get fixed eventually by woocommerce? What can be done?  * [carolm29 (woo-hc)](https://wordpress.org/support/users/carolm29/) * (@carolm29) * [2 years ago](https://wordpress.org/support/topic/getting-an-error-billing-postcode-zip-is-not-a-valid-postcode-on-poland/#post-17755091) * Hey, [@optimalprime](https://wordpress.org/support/users/optimalprime/)! * I’m afraid I’m a bit lost. * You quoted: “so there might have been adjustments made to its validation rules.” As it was an answer from us, but I don’t see this in this thread. * Are you still having issues with the Poland Zip code or is this last message about something else? * Looking forward to your reply. * Have a wonderful day! * Thread Starter [optimalprime](https://wordpress.org/support/users/optimalprime/) * (@optimalprime) * [2 years ago](https://wordpress.org/support/topic/getting-an-error-billing-postcode-zip-is-not-a-valid-postcode-on-poland/#post-17762654) * Hello, Yes a message was deleted, Guess someone else responded on the question aswell. This was the answer I got. Yes the problem with Poland (and Portugal) exists unless I take away (disable not hide) the fields entirely, which I did as a workaround. But I still dont get why 2 countries only would give this error. * Femi wrote: * Hello * You may want to review the settings or code related to the zip code field validation. How was the zip code field made optional? Typically, this field is mandatory by default, so there might have been adjustments made to its validation rules. However, it’s conceivable that these adjustments weren’t applied universally, resulting in the field being required for some countries while optional for others. * Plugin Support [omarfpg a11n](https://wordpress.org/support/users/omarfpg/) * (@omarfpg) * [2 years ago](https://wordpress.org/support/topic/getting-an-error-billing-postcode-zip-is-not-a-valid-postcode-on-poland/#post-17763907) * Hi [@optimalprime](https://wordpress.org/support/users/optimalprime/), * Can you share more details about these code modifications you’ve made?

If it doesn’t, then the issue is likely related to your modifications. * If the issue persists even after removing the custom code, it would be helpful to know if you have any other customizations or plugins that might be affecting the checkout process. * If you haven’t already, I recommend updating all your WooCommerce plugins, themes, and WordPress to their latest versions. This can help ensure that you have the latest fixes and improvements that might resolve your issue. * Please let us know how it goes or if you need further assistance.
