Summary
This case study documents the implementation of the CAMARA-standardised Know Your Customer Match API by Millennium Cobranças y Crediativos, a company engaged in debt collection for banks and financial institutions in Brazil. The primary objective of the implementation was to enhance contact accuracy and reduce operational costs associated with unproductive calls due to invalid or outdated phone numbers. Prior to the API's implementation, Millennium faced significant challenges, with over two million daily calls resulting in low success rates of 3.5–5%. The API allows for pre-validation of identity against Telefónica's KYC records, leading to a reduction in daily calls from over two million to approximately 250,000 and an increase in accuracy rates to 18–23%. This shift has not only minimized compliance risks with ANATEL regulations but has also improved cost-efficiency, resulting in a 12–15% reduction in telecom and messaging expenses.
