How this service works
Validate and format a Chilean RUT (tax ID) including check digit (modulo 11). Use when a Chilean RUT is entered in a form or file and you must catch typos before saving.
Output
Returns a JSON object with three fields: 'rut' (the original input), 'valid' (a boolean indicating whether the RUT passes modulo-11 check digit verification), and 'formatted' (the RUT in canonical Chilean dotted-dash format, e.g. '12.345.678-9').
Example use cases
Form input validation before save
“I'm about to save a customer record with RUT 76.354.771-K — can you verify it's valid and give me the properly formatted version?”
Batch data cleanup before import
“We have a Chilean client whose RUT was entered as 123456789 — can you check if that's a valid RUT and show me how it should be formatted?”
Catching typo in tax document
“Someone submitted a Chilean tax form with RUT 9.876.543-2 — can you confirm whether the check digit is correct so I know if there's a typo?”
Technical details
Endpoint
POSThttps://toolrail.dev/cl/rut?utm_source=zero.xyzWhen to prefer
Use this endpoint whenever you need to verify a Chilean RUT before persisting it to a database, processing a payment, or submitting a government form. It is purpose-built for Chilean tax IDs with native modulo-11 logic, unlike generic regex validators that miss check-digit errors. Prefer it over manual validation or generic form libraries when accuracy and canonical formatting are both required.
Side effects
- Malformed or empty RUT string returns valid: false with no formatted output
- Non-Chilean ID formats (e.g. Colombian cédula, Argentine CUIT) may return invalid unexpectedly
- RUT with letters other than 'K' as check digit will be flagged invalid
- Network timeout or upstream error returns HTTP 5xx
