Using your Postcodes4u Product Key
When you create a Postcodes4u Account you are given a product key which is used to access your postcode lookups. You can monitor how your credits are being used from the My Account
section of the website using the Credit Usage
Report. If you wish to use your Postcode lookups on a number of different websites or in different areas of your website, you may wish to create new Postcodes4u keys. Using different keys you can more accurately monitor where the postcode lookups lookups are being used. To create a key, visit the Postcodes4u Keys
tab in the My Account
section of the website.
Click the Postcode Finder
You will be requested to enter a descriptive name for your key. This key name helps to track usage and also provides you with a unique key to access the service. Also enter a daily limit for the number of credits that this key can use.
Once this information has been entered, the Products Keys tab will display the key XXXX-XXXX-XXXX-XXXX that can be used to access the service.
