Native IBAN Input Field with Validation
It would be great to have a native IBAN input field that automatically validates the IBAN format and checksum in real-time as the user types.

Thanks for getting back to me! I've already seen and upvoted the general regex/input validation request. However, I wanted to specifically highlight that for fields like IBANs (as well as credit cards or national tax IDs), standard regex pattern matching only verifies the structure/length, but cannot detect typographical errors. A true native validation requires a mathematical checksum check Is there any consideration to support checksum algorithms or allow custom mathematical validation rules alongside the planned regex feature? This would provide far more robust data quality and prevent invalid entries at the source.
Hey Paul — thanks a ton for the feature request and for being a Tally user! We love hearing from you. ✌️ The more general regex/input validation request would be this; https://tally.so/feedback/board/p/input-validation-regex
