NIE requires accurate capture and maintenance of phone numbers. This could also be seen as beneficial for all Market Participants. The phone number data model and strategy is important from a customer service perspective.
Currently, there is no way of identifying which phone number is a mobile, work, home number in any inbound Idoc. The Central Market System does not store any number in this categorisation, making it difficult to transfer phone numbers accurately to all the feeder systems and subsequently back to Suppliers.
Without phone number categorisation, it is difficult to provide updates to the correct phone numbers in the Central Market System. This is resulting in existing numbers being overridden, sent to feeder systems as the incorrect type of phone number and generally being an inaccurate representation of customer data.
