The Phone Number Advanced endpoint returns a full NIN identity profile associated with a given phone number, including numbers beyond the primary registration. Use this when you need to verify additional phone numbers linked to a customer’s NIN.
For the primary phone number registered to an NIN, use Phone Number Basic — it is faster and returns core identity fields.
