The agreement follows multiple tests carried out at the end of 2019 using the Verify platform.
Location Sciences has also signed a partnership agreement with Horizon Media, one of the world’s leading independent media agencies.
Accurate data remains an ongoing problem for the advertising sector with over half of local advertising campaigns the subject of fraud and inaccuracies according to the company.
Mark Slade, Location Sciences' chief executive, said: "These agreements are pivotal for us as we operate in an emerging market.
“Furthermore, they demonstrate that the relevant stakeholders in these large multi-national agencies recognise the potential of, and back, our technology and capabilities.
“While we are still relatively early in our journey as a business, these agreements give us access to a large pool of location advertising spend.”
