Where is the driver's license security code and what is it for? 

Where the driver's license security code is located is a common question that always arises at specific times.

And with so much information in a single document, it can be difficult to locate data, especially when it's not requested frequently.

But what is this code, and what is it for? How do I find it on the physical document? And what about the digital CNH?

All of these questions will be present in the following content, so continue reading to clear up all your doubts on this subject!

What is the CNH security code?

The CNH (National Driver's License) is one of the main identification documents accepted in Brazil.

In many cases, qualified citizens end up leaving their ID card in the drawer and only using their driver's license in their daily lives.

The reason for this is usually practicality, since to drive you need to carry your driver's license, and if this already serves as your identity document, there is no need to fill your pockets with more documents.

But, going beyond practicality, for a long time the CNH was considered the favorite because it had more complete information about the holder.

This is because, for a long time, the oldest ones did not have the holder's CPF, nor did they have much information other than full name, document number, affiliation, signature and fingerprint.

The CNH has always had all this information (with the exception of the digital one), and also included some additional items that facilitate the creation of records and the identification process.

So, it is clear that there is no shortage of reasons why the CNH has been adopted by Brazilians as a practical and useful identification document.

However, the CNH has a specific item, which is the security code, which many people are unaware of its function.

The security code is a number made up of 11 (digits) digits, and, as the name suggests, exists for security reasons.

In this way, the code helps verify the holder's information, validates online/digital services, and also helps prevent fraud.

Therefore, knowing where your driver's license security code is located is very important, as it may be requested on different occasions.

Where is the CNH security code?

By now you already know that the CNH is much more than a document that allows the holder to drive a vehicle, it is also an important identification document.

Furthermore, you also understand that the security code is crucial for granting access to online services related to the CNH, and also serves as a document protection item.

This makes it easy to understand that knowing where the driver's license security code is located is just as important as other information.

Therefore, we will now see where this information is located specifically on each CNH model currently in circulation.

The first thing you should look at before looking for the code is the year the driver's license was issued.

This is because, if the document was issued before May 2017, the code is numeric.

If it was issued after that date, the code became a QR Code.

Therefore, if your driver's license is the latest model, simply look for the QR Code to locate the security code.

But if your model is the older one, then you will have to look for the code on the back of the document.

This is located just below the document's issue date, above another code that starts with the federative unit of the Detran responsible for issuing the CNH.

It is worth highlighting that this code has 11 (eleven digits).

It is important to note that to use the QR Code, you must scan it using a compatible device.

Does the digital license have a security code?

The digital CNH has gained a lot of ground since its creation.

This is because its use eliminates the need for the driver to present the physical version.

This means that the driver who presents the digital version on their device does not need to carry the physical CNH.

Therefore, it is important to know about the security code in this version.

After all, is there a security code on the digital license?

And, as we have seen, this code is intended to guarantee the authenticity of the document.

Therefore, the digital CNH certainly has the security code.

This code is usually a QR Code, but this varies depending on the state where the license was issued.

In any case, knowing where the CNH security code is in the digital version is not difficult, since it follows the same rules as the physical version.

CDT x digital CNH: what are the differences?

It is a fact that the Brazilian licensing system has undergone significant changes in recent years.

This is because, if before there was only the physical document, now it is possible to carry only the digital version.

Additionally, some other features have emerged, and one of them is the CDT, which many believe will replace the Digital CNH, but is this true?

The CDT or Digital Transit Wallet is an application that stores and brings together the digital CNH and the vehicle document.

This means that when using the CDT, you will have your vehicle documents on your cell phone.

Therefore, it is easy to understand that the CDT is not a type of license, and much less does it replace the CNH.

The CNH remains the official vehicle license in Brazil.

However, the CDT is here to facilitate access, as it concentrates all the necessary documents in one place.

This way, you'll never have to worry about being stopped at a checkpoint and forgetting your documents at home.

But for this to happen, you must have access to your driver's license and vehicle documents in digital form.

From there, just open the app and present the requested documents whenever you need! 

This makes it easy to know where your driver's license security code is, and so much other important related information!
