CSV IBAN Validation Safety

Who this guide is useful for

People checking multiple IBAN values from spreadsheets, payment batches, vendor lists, customer records, or test datasets.

Treat pasted lists as sensitive

A pasted list can contain real payment details, customer records, vendor details, or internal references. Even when validation runs locally, the pasted text and exported results should be handled carefully.

What BankCodeKit can check

The Bulk IBAN Validator can check one IBAN per line for country support, expected length, allowed characters, and checksum status in the browser. It does not upload files or verify real accounts.

Handle CSV exports carefully

A CSV export can include the values you pasted and the validation result for each row. Do not email, paste into shared chats, publish, or store the export in a public location unless you have a separate trusted process and permission to handle that data.

What BankCodeKit cannot check

BankCodeKit cannot verify that the list is authorized to use, that every row belongs to the intended recipient, or that a payment batch is ready to send.

Practical CSV review example

Bulk validation can support cleanup without turning the CSV into an approved payment file.

Paste one IBAN per line into the Bulk IBAN Validator.
Review invalid rows for country, length, character, or checksum issues.
Keep the CSV export in a controlled location if you need to retain it.
Confirm real payment batches through your own trusted bank, provider, or internal process.

Important limitations

BankCodeKit validates format and reference data only. It does not confirm account existence, account ownership, bank connectivity, sanctions status, fraud risk, payment readiness, or payment success.

Bulk validation checks visible IBAN format only.
It does not verify account existence, account ownership, payment readiness, or payment success.
A CSV export can contain sensitive payment details and should not be emailed or publicly shared without a separate trusted process.
BankCodeKit does not provide data-governance, legal, tax, or banking advice.

FAQ

Is my pasted CSV uploaded?

No. BankCodeKit's bulk validation is designed to run in the browser, but the data you paste can still be sensitive.

Can I email the validation export?

Avoid emailing or publicly sharing exports unless you have a separate trusted process and permission to handle that data.

Does a valid row mean the payment can be sent?

No. A valid row means the visible IBAN format passed supported checks only.

Should test data be marked differently?

Yes. Keep synthetic or test data clearly separated from real payment data so it is not mistaken for a live instruction.

Sources and update note

BankCodeKit uses local IBAN reference data and browser-local format rules for country, length, character, and checksum checks. The official Swift IBAN information is used as a reference source, but BankCodeKit does not query Swift or any bank while you use the tool. Reference data is reviewed periodically and does not imply live accuracy.
