In a world where identity fraud and digital scams are on the rise, verifying who’s really behind an ID has never been more important. For businesses in Guatemala, especially those operating online or managing customer onboarding, the Código Único de Identificación (CUI) plays a key role in confirming a citizen’s authenticity.
Whether it’s a financial institution verifying loan applicants or an e-commerce platform validating new users, accuracy and speed are everything. Manual ID checks often slow down processes and open the door to errors. That’s where Verifik’s CUI verification API comes in, which offers an automated, secure, and instant solution that helps businesses verify Guatemalan identities in seconds.
What is CUI and How It Works in Guatemala?
The CUI, or Código Único de Identificación, is the official national identification number assigned to every Guatemalan citizen. It serves as a unique digital and physical identifier used across government, financial, and legal systems.
From opening a bank account to accessing government services, the CUI is essential for proving identity. Each number is unique to the individual, making it a reliable way for organizations to confirm that a person is who they claim to be.
By verifying the CUI, businesses and institutions can ensure they are interacting with legitimate individuals, reduce the risk of fraud, and maintain compliance with national regulations.
