RUT / NIT check
Paste a Colombian RUT or NIT and get a quick format sanity check before banking or vendor forms. This is not a RUES / DIAN registry lookup — it only helps catch missing digits and odd lengths.
How to use
- Paste digits (with or without check digit).
- Read length / format feedback.
- Confirm against your official RUT document.
What the tool does
Checks digit length and basic formatting on-device.
What the tool does not do
Does not query DIAN/RUES or validate the check digit against the registry.
Tips
- Strip spaces and punctuation before comparing to paperwork.
- Keep the DV (check digit) consistent with your ID card.
