However, in cases where there is no match, it is necessary to contact the customer to get the correct address, as best practice. For example, the country of residence specified by the customer must be the same as the country in which the mobile phone number is registered. Carrying out such checks allows us to prevent fraud and significantly improve the customer experience by delivering shipments to the right address, to the right person. We also don’t have to pay for packages sent to the wrong address.
