Where is the ID on the CNH? check out

Know where is the ID on the CNH It can be important at various times when we need the number of this document, but we do not have the original ID on hand, only the driver's license.

The National Driving License (CNH) is one of the most important documents for Brazilian drivers, not only because of its main function of legally allowing the driving of vehicles, but also because it is widely accepted as an identification document.

Although it is a practical substitute for the identity document (RG) in many situations, it is common for people to not know where to find this number, and here, you can find out everything about the subject!

Understanding the CNH: a complete identification document

Firstly, before highlighting where is the ID on the CNH, it is important to clarify that the CNH is issued by the State Traffic Departments (DETRANs) and follows a standard established by the National Traffic Council (CONTRAN).

It contains various personal information about the driver, including name, date of birth, affiliation, photo, signature, and a national registration number – the Renach number (National Driving License Registry).

Where is the ID on the CNH?

In the current CNH model, any driver can find their ID number in the “DOC. IDENTITY/ORG. UF EMITTER”. This can be used whenever necessary in everyday life.

In the vast majority of situations, the CNH is accepted as an identification document, and even without the original ID in hand, the driver's license will be legally valid to confirm your data.


Driver's license as identity document

Now that you know where is the ID on the CNH, it is worth mentioning that this document is often used as an identity document in many contexts as it is a federal document, containing the bearer's photo and signature, which facilitates identification.

When is ID Necessary?

Although the CNH is a valid document for most everyday situations, there are certain moments and procedures in which the presentation of the ID is essential.

This is due to the need for a civil identity document issued by a state identification agency, which contains information that is not present on the CNH, such as the driver's license number. RG original.

Digitization and modernization of documents

With the digitization and introduction of electronic documents, such as the e-RG and CNH Digital, access and management of personal documents have become simpler and safer.

The Digital CNH, for example, can be accessed through smartphone applications and is legally equivalent to the physical version, containing all the information necessary to identify the driver.

Here you can check where is the ID on the CNH, and this data will be located in exactly the same field in the virtual version, so just check your document to find it.


In short, find where is the ID on the CNH it's very simple. The CNH serves as a robust form of personal identification, but does not completely replace the ID in all legal and administrative contexts.

It is essential that citizens are aware of the differences and specific validity of each document to avoid setbacks and ensure adequate proof of identity where necessary.

This understanding not only clarifies a common doubt, but also helps in the personal organization of documents, ensuring that each situation is faced with the correct documentation. Therefore, while the CNH is an extremely useful and practical document, it is essential to always have the ID document available or even opt for its digital versions, depending on the need and context.
