Called Qudox, the service provides a link to Global Address's server, allowing customers' own websites to validate addresses on a pay-as-you-go basis.
Further features will be added to the service after it is launched in May.
Martin Turvey, CEO of Global Address, said: "Qudox is ideal for organisations that want to make low-to-medium volume country data requests to our hosted server. It's quick, easy and puts the customers in charge.
"You register, copy the code, make the payment and you're done. From then on, your website can be validating addresses from Milan, Mexico or wherever in an instant."
