 * Hi,
 * I’m randomly getting an invalid postcode error when customers try to checkout.
   It is difficult to reproduce and happens frequently. Are there any known plugin
   conflicts or things I can check to find out what is causing it?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Finvalid-postcode-error%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi [@bencalder](https://wordpress.org/support/users/bencalder/). An intermittent
   issue with invalid postcode errors suggest a caching issue, so I’d recommend 
   checking your caching plugins. We have a [guide here](https://docs.woocommerce.com/document/configuring-caching-plugins/)
   for setting up caching plugins.
 * Aside from that, you can do a general conflict test using this guide – [https://docs.woocommerce.com/document/how-to-test-for-conflicts/](https://docs.woocommerce.com/document/how-to-test-for-conflicts/)
 * I hope that helps!

 * 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.
