About This Tool

The IBAN generator constructs a valid international bank account number using country code, bank code, and account data. It follows ISO 13616 standards to assemble the BBAN and calculate the two checksum digits, producing an IBAN suitable for testing payment integrations and reconciliation workflows. The tool performs country-aware BBAN assembly, applies the mod-97-10 checksum, and outputs both raw and optionally formatted strings. It supports deterministic outputs across environments and provides clear error codes for missing or invalid inputs. Audience includes developers, QA engineers, and finance teams working on cross-border payment testing. Use cases cover API integration testing, ledger validation, and data quality checks without requiring live bank data.

Frequently Asked Questions

Find Quick Answers

What data is required to generate an IBAN?
Required fields include country_code, bank_code, and account_number. Optional fields such as branch_code and account_suffix refine the BBAN. All inputs are normalized to uppercase alphanumerics before processing to ensure consistency.
Does the tool validate against live bank databases?
No. It validates IBAN structure and the mod-97-10 checksum per ISO 13616 but does not connect to live banking networks or verify that a bank account exists.
Can it generate IBANs for all countries?
Generation relies on country-specific BBAN patterns. The tool covers common European formats and select regional patterns; unsupported countries may return an error indicating lack of pattern support.
How is the checksum calculated?
The standard MOD-97-10 algorithm is used: move the country code and checksum to the end, replace letters with numbers, compute the remainder, and derive the two-digit checksum to prepend to the BBAN.
