IBAN check: Validation of bank details in Procurement
November 19, 2025
The IBAN check is an essential validation process for checking the correctness of bank details in procurement. It ensures error-free payment processing and minimizes risks in supplier transactions. Find out below what IBAN verification means, which methods are used and how it is strategically applied in Procurement .
Key Facts
- Mathematical validation of the IBAN structure using the modulo-97 method
- Reduces payment errors by up to 95% in supplier transactions
- Automated integration into ERP systems and procurement platforms possible
- Legal requirement for SEPA payments in the EU
- Can be combined with BIC validation for complete bank data verification

Definition: IBAN check
The IBAN check refers to the systematic validation of the International Bank Account Number to ensure correct bank details in the procurement process.
Basic components of IBAN validation
A complete IBAN check comprises several validation levels:
- Length check according to country-specific standards
- Structure validation of characters and positions
- Mathematical check digit calculation according to ISO 13616
- Bank sort code comparison with current directories
IBAN check vs. traditional account validation
In contrast to conventional account number validation, IBAN validation offers international standardization and higher error detection rates. The BIC-SWIFT codes complement the IBAN check for complete bank identification.
Importance of the IBAN check in Procurement
IBAN validation is critical for procurement organizations to avoid payment errors and compliance violations. It supports data quality in supplier master data and reduces operational risks in invoice processing.
Methods and procedure for IBAN checks
IBAN validation is implemented using various technical and organizational approaches to ensure maximum data quality.
Automated validation procedures
Modern procurement systems integrate IBAN checks directly into the data entry processes. The modulo-97 method in accordance with ISO 13616 forms the mathematical core of the validation.
- Real-time validation for supplier registration
- Batch processing for master data cleansing
- API-based validation services
Integration in master data management
The IBAN check is systematically embedded in master data governance processes. Data stewards monitor the validation quality and exception handling.
Quality assurance and monitoring
Continuous monitoring of validation results using data quality KPIs ensures sustainable data quality. Regular audits identify potential for improvement in the validation processes.
Tacto Intelligence
Combines deep procurement knowledge with the most powerful AI agents for strong Procurement.
Important KPIs for IBAN checks
IBAN validation quality is measured using specific key figures that ensure operational excellence and risk minimization.
Validation accuracy and error rates
The validation accuracy measures the proportion of correctly identified IBAN errors in all checked bank details. Target values are typically over 99.5% for automated validation processes.
- False positive rate for IBAN rejections
- False negative rate for incorrect IBANs
- Average validation time per data set
Process efficiency metrics
Operational KPIs evaluate the efficiency of the IBAN verification processes in the procurement context. The Data Quality Score integrates various quality dimensions into an overall assessment.
Compliance and key audit figures
Regulatory KPIs monitor compliance with SEPA requirements and internal guidelines. Audit trail completeness and documentation quality are key evaluation criteria for compliance assessments.
Risks, dependencies and countermeasures
The IBAN check involves specific risks and dependencies that must be minimized through appropriate measures.
Technical default risks
System failures in validation services can block procurement processes. Redundant validation systems and offline fallback mechanisms ensure business continuity even in the event of technical faults.
Data quality risks
Incomplete or outdated IBAN reference data leads to incorrect validations. Regular updates of the reference data and data cleansing processes minimize these risks.
Compliance and regulatory dependencies
Changes in SEPA regulations or national banking standards require adjustments to the validation logic. Proactive monitoring of regulatory developments and flexible system architectures significantly reduce compliance risks.

Practical example
A medium-sized mechanical engineering company implements automated IBAN checking in its supplier management. When registering new suppliers, the system validates all bank details in real time and identifies 12% incorrect IBANs before the first payment is made. The integration reduces payment returns by 89% and saves 15 hours of manual correction work per month.
- Automatic validation for supplier registration
- Immediate error message with correction request
- Quarterly batch validation of all master data
Trends & developments around IBAN checks
The digitalization of finance and new technologies are changing the requirements and possibilities of IBAN validation in the procurement environment.
AI-supported validation optimization
Artificial intelligence is revolutionizing IBAN verification through advanced pattern recognition and predictive validation. Machine learning algorithms identify suspicious bank details and automatically optimize validation rules.
Real-Time Payment Integration
The increasing prevalence of instant payments requires accelerated IBAN validation processes. Cloud-based validation services enable real-time checks with minimal latency for time-critical procurement transactions.
Blockchain-based bank data verification
Distributed ledger technologies create new possibilities for decentralized IBAN validation and bank data verification. This development promises increased transparency and protection against manipulation in supplier data validation.
Conclusion
IBAN validation is an indispensable tool for ensuring error-free payment processes in modern procurement. Automated validation enables companies to significantly reduce operational risks and improve the efficiency of their financial processes. Integration into comprehensive data quality strategies maximizes the benefits and creates sustainable competitive advantages. Future technologies such as AI and blockchain will further increase validation quality.
FAQ
What exactly does IBAN validation check?
The IBAN check validates the mathematical correctness of the check digits, the length conformity according to country standards and the structural integrity of the bank details. It reliably detects typing errors and invalid account number combinations.
How often should IBAN data be validated in Procurement ?
Ideally, IBAN validation takes place with every data entry and in regular batch processes. Quarterly full validations of all supplier master data ensure continuous data quality and identify interim changes.
What costs are incurred due to incorrect IBANs?
Incorrect IBANs cause chargeback fees of EUR 5-25 per transaction, delays in supplier payments and increased manual correction work. In addition, opportunity costs arise due to disrupted supplier relationships.
Can IBAN checks also detect attempted fraud?
IBAN validation primarily detects technical errors, but not deliberate manipulation with valid third-party bank details. Additional plausibility checks and supplier verification processes are required for comprehensive fraud protection.
