Frequently asked questions

Why do I get the error "License key is no longer valid, it may have expired"?

This error is generated whenever you try and do a lookup using a key that has been deleted, or has expired. Licence keys can be deleted through your account online; if you do this by mistake you’ll need to contact us to get them reinstated. With annual user licences available for the Royal Mail's Postcode Address File (PAF®) data, this error will be displayed if you have not renewed and the licence has expired, again please contact us.

What does the error "The licence key has reached its daily limit, please check your settings or wait until tomorrow" mean?

Each per-click licence key has a setting that dictates the total credit it can consume from the account on a single calendar day. This is a security setting to help protect your credit from being consumed too quickly. It can be changed within the edit wizard of the licence key in question. If you are using a user licence key then the daily limit will be set at the time of purchase, in accordance with our fair usage policy.

What does the error "This license key cannot be used from this website, the security settings for the license key may not include this domain" mean?

Within your key settings you have the option to limit our service to only accept requests on that key that are coming from specified website addresses. This is a security feature to prevent your key from being used anywhere other than the site you intended. If you set this up and get this error message please check the URL is formatted correctly and is available. The website address will be detailed in the table in the email.

Why do I have the error "Your credit has run out"?

This means your account has run out of credit. An error message email will be generated when a user tries to do a lookup. The error will usually show the IP, or URL where the request originated and details of the service that was used. To fix this, log into your account and top up with credit.

What does the error message "Free Service Limit Exceeded" mean?

The Free Service Limit Exceeded error occurs automatically when there are a significantly higher number of uncharged requests in comparison to charged. For example, when using the address validation service, a find (free) request should usually be followed by a retrieve (charged) request. This error is highlighting an imbalance in free and charged calls to the service. Check the usage on your account under Menu > Reporting to see if the service has been installed correctly. If the calls to the service are dramatically imbalanced please get in touch with our support team.
