How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 48% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from. A declining trend compresses what a buyer would pay.

   Have used other address and postcode validation software but have found Ideal Postcodes to work extremely well and is easy to configure for many form builder plugins. Works well in all browsers and can be configured with hidden fields, this enables me to make the form attractive and easy to use for my clients but ensures I get the correct address in the correct format with the various fields for easy import in to my database. Support has also been second to none, I would recommend Ideal Postcodes and the plugins, I am currently using on several websites.

   Cannot recommend this plugin highly enough. Very simple to use, and the cheapest postcode validation available in the UK for smaller volume users like me. The plugin installs very simply, and integrates with woocommerce beautifully. Their own website where you can set up and manage your account is fantastic for keeping tabs on all aspects of your usage, and is also simple to use. Their user support via chat channels is super responsive. This should be bundled with woocommerce for UK users. Nothing is simpler for postcode validation
