CNH Digital: How to Download, Validate & Share on Smartphone
Step-by-step CNH Digital guide: Carteira Digital de Trânsito (CDT) app, Gov.br biometric verification, Vio QR code validity, and sharing digital vehicle title (CRLV-e).
How do you download and validate the CNH Digital and does it have the same legal validity as the printed driver's license?
Statutory Legal Equivalence and the Carteira Digital de Trânsito (CDT)
Enacted under Contran Resolution nº 684/2017 and reinforced by the Traffic Code Reform (Law nº 14.071/2020), the electronic driver's license (CNH-e) completely eliminated the legal necessity of carrying the physical paper document. Traffic enforcement agents (Polícia Rodoviária Federal, Polícias Militares, and municipal traffic authorities) are legally bound to accept the digital presentation through the official CDT app.
Authenticity is guaranteed via the Vio QR Code system developed by the federal technology agency Serpro. When an officer scans the QR Code, the system cryptographically validates the driver's registration directly against the Renach (Registro Nacional de Carteiras de Habilitação) database, displaying current status, restrictions (such as glasses requirements), and expiration dates even if the officer's device is temporarily offline.
Facial Biometric Enrollment and Multi-User Vehicle Sharing
Activating the CNH Digital no longer requires an in-person visit to a local Detran branch. Drivers download the Carteira Digital de Trânsito app from the Google Play Store or Apple App Store, authenticate through Gov.br, and perform facial biometric validation using their smartphone's front camera. The facial scan is cross-referenced in real time against the national biometric image repository recorded during initial licensing or renewal.
Beyond personal driver credentials, the CDT incorporates the Certificado de Registro e Licenciamento de Veículo digital (CRLV-e). Vehicle owners can store their vehicle title in the app and digitally share the credential with up to five other licensed drivers (e.g. family members or colleagues) who also use the CDT app, eliminating the historical inconvenience of sharing a single paper document.

Step-by-Step SOP to Download and Validate CNH Digital
Download Carteira Digital de Trânsito (CDT) App
Install the official CDT app developed by Serpro from Google Play Store or Apple App Store (never use unofficial third-party apps).
Log In Using Your Gov.br Credentials
Authenticate using your CPF and Gov.br password, ensuring your account is verified at Level Prata or Ouro.
Perform Facial Biometrics via Smartphone Camera
Follow the on-screen prompts (blinking, smiling, turning head) to validate your biometric identity against the national Senatran database.
Create 4-Digit Security Key (Chave de Acesso)
Define a 4-digit PIN code or enable fingerprint/FaceID biometrics to access your CNH Digital and CRLV-e anytime without internet access.

"The Carteira Digital de Trânsito is a triumph of digital public transformation. Over 45 million Brazilian drivers now carry their driver's license and vehicle registration securely in their pocket, eliminating bureaucracy and unnecessary Detran queues."
"All federal, military, and civil police officers are equipped to verify the Vio QR Code. Drivers no longer face impoundment penalties for forgetting physical paper at home as long as their CNH Digital is active."
Perguntas Frequentes (FAQ)
What happens if my phone battery dies during a traffic stop?▼
If your phone battery is depleted and you do not carry the physical document, the officer can still verify your licensing status in the Renach system using your CPF. Under Article 230 of the CTB, as long as the system confirms you are properly licensed, you cannot be fined for not carrying physical paper.
Can I use my CNH Digital as official identification for domestic flights and banks?▼
Yes. Under Federal Decree nº 10.278/2020 and ANAC civil aviation regulations, the CNH Digital within the official CDT app is legally accepted as a valid primary identity document for boarding domestic commercial flights, opening bank accounts, and public notary transactions.
Can I activate the CNH Digital if my physical license was issued before 2017 without a QR Code?▼
No. The security architecture requires the encrypted QR Code printed on the inner fold. If your physical license was issued prior to May 2017 without a QR Code, you must renew your license or request a 2ª via at Detran to receive a QR-enabled document.
