How this service works
Offline validator for a Guatemalan CUI (Código Único de Identificación), the 13-digit national ID number. Parses the 13 digits into an 8-digit correlative, a 1-digit check digit, a 2-digit department code and a 2-digit municipality code, recomputes the check digit using the published weighted mod-11 formula (weights 2-9 over the 8 correlative digits, mod 11, 10→0) and compares it, returning validity plus the parsed components.
Output
Returns a validity boolean plus the parsed components of the CUI: the 8-digit correlative, the 1-digit check digit, the 2-digit department code, and the 2-digit municipality code, along with whether the recomputed check digit matches the input.
Example use cases
KYC identity check for Guatemalan users
“I need to verify that this Guatemalan national ID is legitimate before onboarding the user — can you validate CUI 1234567890123 and tell me if the check digit is correct?”
Form input validation for Guatemala ID field
“A user entered 2845692630101 as their Guatemalan CUI on our sign-up form — can you check if it's a valid ID and also tell me what department and municipality it belongs to?”
Bulk data cleanup for Guatemalan records
“We have a CUI number in our database — 3001234560805 — and I need to know if it passes the official mod-11 check and what its parsed components are.”
