CUIC ‑ CUI CHECKER

This Romanian CUI Validator helps Shopify merchants verify Company Unique Identification Numbers during checkout. The app checks that customer-entered CUIs are valid and properly formatted according to Romanian tax regulations, reducing errors in order processing. The validator is essential for stores using Facturare Gestiune Online (FGO) integration, ensuring CUI authenticity before orders are processed. It prevents common data entry mistakes by validating CUIs in real-time and keeps the company field clean—no more commas or business names where they don't belong. Perfect for Romanian businesses that need accurate tax identification data for compliance and smooth integration with FGO systems.
