For this, there is a mechanism that contributes to a better security of your bank account. Do you know what is account DV?



In this post, you will check the answer to the above question, know the importance of the DV, how to locate it, the difference between the account digit and the agency digit, and some more relevant information.

What is Account DV?

The Check Digit (DV) is an authentication and security tool.

In credit cards, it is this digit that ensures that the number is consistent with an agency or account is in fact true.


Because of this, DV is also called a control algorithm.

On a credit card, the DV of the account is that number that stands alone, separated by a dash (-) or just a space.

It is usually next to your bank account number.

What is the importance of DV?

Now that you know what Account DV is, let's talk about its importance.


The DV is important because it is the DV that confirms whether a bank account exists or not.

In addition, the Check Digit helps to avoid situations where deposits or bank transfers are made fraudulently or wrongly.


For example: if the person tries to make a transfer, but ends up putting the wrong account number of the person who will receive it.


It is the DV that will prevent the money from being transferred to another customer's account or even to an account that does not exist.

It's also worth noting that the Check Digit is so important that it's not just used on cards and bank accounts.


Personal documents also use this security mechanism, as is the case with the CPF.

In short, DV is a fundamental measure for people's safety.

Do all accounts have DV?

Yes. As a security mechanism, both a savings account and a checking account have their own DV as a way of proving that the digit is legitimate.

In addition, it is also worth making it clear that digital accounts also have this mechanism.

For example, if you make a purchase on an e-commerce site and choose the debit card as a payment method, the store may ask you to enter the Verification Digit of your account to carry out the transaction more safely.


Account digit and branch digit are different numbers

Attention! The bank account Check Digit is not the same as the branch digit.

Both have the same function, they even have the same format, as they are algorithms that are isolated from the other numbers and the sequence continues after a dash, but they are used for different operations.

In this case, the fundamental difference between the two DVs is that it is not all the times that the agency digit will need to be used by the client.



That way, in most situations, when making a purchase in an online store or making a transfer between accounts, there is no need to put the agency's DV.


In these same operations, the Account Verification Digit is requested most of the time.

Where can I find the Account Verification Digit?

In general, the Check Digit of all banks is in the same place. You just need to have your credit card in hand and follow these steps to find out where the DV is:

  1. Banco Itaú: you check the Verification Digit of this bank's account on the back of your credit card, right after the sequence of five account numbers, with the sixth number after the hyphen being the DV of the account;
  2. Banco Bradesco: most of the time, customers of this bank find the DV on the front of the card, right after the account number;
  3. Caixa Econômica Federal: here is another bank that uses the DV on the front of the Caixa card, it appears right after the account number;
  4. Bank of our country: in the case of BB, the Verification Digit is also on the front, right after the sequence of account numbers;
  5. Banco Santander: at Santander, there is a variation of where the Verification Digit is. On some cards, the DV is on the front and on others on the back. But anyway, the DV can be found right after the account number (after the hyphen).
  6. Banco Inter: also follows one of the standards on Banco Inter cards, where the DV is on the back.

The category of digital banks follows a slightly different methodology from traditional banks.

In this way, fintechs, such as Nubank, this digit is not entered with your account data on credit cards without an annual fee.


So, to find the DV, you need to access a digital account in your app and go to the “Profile” tab. On this page, you will be able to find your Check Digit information.

At the bottom of this same tab, you will see a QR Code. There you can also see your account number, including the DV right after the hyphen.

What to do if my account has two Check Digits?

In addition to all the situations already mentioned, some financial institutions use two Check Digits, as is the case with Citibank and HSBC.

With this, customers can end up getting confused when making a purchase in online stores or even when they need to access the Federal Revenue system, since the site only accepts accounts with only one DV.

However, it's ok, you don't have to worry, even to answer the question in this topic, the solution is much simpler than you can imagine.


If your account has two Verification Digits, you would consider using only the last number, which is linked to your personal account number.

Now you know what an account DV is and can locate yours.
