A credit union cleanses its member base by re-validating CPFs
How a credit union can cleanse its member base, update records and cut costs by re-validating CPFs in batch against the official source.
The challenge
Over the years, a credit union built up a member base with outdated data: old addresses, invalid phone numbers and even deceased holders still active in the records. This raised communication costs, distorted reports and created LGPD compliance risk, while making it harder to base credit decisions on reliable data.
The solution
The credit union began re-validating its base in batch against the official source. CPFs are resubmitted periodically to confirm the registration status and refresh the linked data; records with a deceased-holder CPF or irregular status are flagged for handling. Recurring cleansing keeps the base clean and aligned with the LGPD’s data-minimisation and data-quality principles.
Results
- Member base re-validated in batch against the official source, on a recurring basis.
- Records with deceased-holder CPFs or irregular status identified.
- Lower communication costs from outdated contact data.
- A more reliable base for reporting, credit and LGPD compliance.
Re-validating the base in batch turned an old, noisy database into a reliable asset for decisions and compliance.
