Validador RUC / Cédula (Ecuador) is a Chrome extension designed to facilitate the quick verification of tax identification information and the structural validity of Ecuadorian documents. This free tool allows users to validate RUC numbers and Ecuadorian cédulas efficiently. It checks RUCs online against the SRI, providing essential taxpayer information, including the business name, RUC status, taxpayer type, accounting obligations, and primary economic activity.

In addition to RUC validation, the extension also validates cédula numbers using an official algorithm that applies structural checks such as province, third digit, and verification digit. While it confirms the format and verification digit of the cédula, it does not validate the existence of the ID in the Civil Registry. This tool is particularly useful for billing, sales, customer service, data validation, and internal processes requiring quick checks before data entry.
