IBAN Validator

Use the free IBAN Validator to validate IBAN numbers for Pakistan, EU, UK and 80+ countries with mod-97 checksum.

That is the whole scope of the page. It sits in Converters & Generators, the group for data converters & generators. The IBAN Validator only does the job in that first sentence.

IBAN Validator runs in your browser. The file or the figures stay on your device, and the free plan does not ask you to create an account.

Use it when you have data in one shape and you need the other shape named in the description.

Open it when you need to validate IBAN numbers for Pakistan, EU, UK and 80+ countries with mod-97 checksum. If you need a different output, pick the tool whose description names that output.

Paste a sample that matches the format. Fix the first error the tool reports before you convert a large file.

Run it once with the values you have. The result should line up with this promise: Validate IBAN numbers for Pakistan, EU, UK and 80+ countries with mod-97 checksum. Change one field if you want a second case, and keep the other fields the same so you can see what moved.

Open the output in the program that will consume it. A file that looks right in the browser can still miss a column.

Keep the units, the dates, and the file type that the form showed. A number from the IBAN Validator is ready to copy only after you have checked it against the labels on this page.

The converter follows the rules on this page. It does not invent columns that were not in the input.

Anything the description does not mention is outside this tool. Use the result as the estimate or the file this page promised, then check the source that actually applies to your bank, school, client, or project.

Other tools in Converters & Generators include Barcode Generator, Hash Generator (MD5 / SHA), Color Converter (HEX / RGB / HSL), vCard Generator, Schema Markup Validator and .env Validator. Open the one whose description matches the next job.
