Account tracking in South African banking is a service that monitors a set of bank account numbers for changes — such as account closure, account number change due to a bank migration, or account status changes. It is typically used by EFT collecting businesses to proactively detect when a debtor changes their bank account, switches banks, or closes their account. Early detection allows the collecting business to update the DebiCheck mandate or request updated banking details before the next collection, preventing failed EFT debits, return item fees, and the associated cashflow impact.

Account tracking integrates with the DebiCheck mandate lifecycle by monitoring the bank account numbers linked to active mandates. When an account change is detected — typically through bank notification systems or periodic batch checks via PayInc (BankservAfrica) — the tracking system flags the affected mandate. The collecting business is notified to request updated banking details from the debtor. A new DebiCheck mandate must then be created and authenticated for the updated account before collections can resume. Without account tracking, the first indication of an account change is usually a failed collection with a return reason code, by which time the business has already incurred the return fee.

Common EFT collection failure reasons (return codes) in South Africa include: insufficient funds (the most common reason); account closed or does not exist; incorrect account details (wrong account number — prevented by CDV and AVS); account holder's identity does not match (prevented by AVS); debit order cancelled or not authorised; account type not suitable for debits; and bank migration causing account number changes (prevented by account tracking). Return item fees charged by South African banks typically range from R10 to R25 per returned item, which adds up significantly for high-volume collectors with a poor quality debtor book.

Yes. Bank migrations — such as the ongoing Capitec Business banking migrations or legacy bank consolidations — can change a debtor's account number without their explicit action. Account tracking services monitor for these changes by cross-referencing account numbers against bank notification systems. When a migration event is detected, the account tracking system can sometimes automatically map the old account number to the new one, or alert the collector to request reconfirmation. This is particularly important during large bank mergers or platform migrations, where thousands of account numbers may change simultaneously.
