IBAN: what is it, and what is it for?

The IBAN code is the account number identification code, and it has a great impact on the financial world and the day-to-day operations of all banking users

Promoted product

When a transfer is made, the IBAN alphanumeric code (International Bank Account Number) is always used. As its name indicates, it is used to identify any bank account in the countries that use it. It has its origins in the EU, but many other countries such as the USA, Canada and much of South America have already joined. As a result, the IBAN system is used all over the world.

Why was it created? Previously, international payments posed certain problems for users. Each country had its own conditions and rates. Sometimes, it was also difficult to know what country a certain bank account was in. With the arrival of this code, financial institutions were able to automate their transfers. 

The function of the IBAN is similar to the euro's, since it allows transactions to be made as if they were in the same country. This eliminates the bureaucracy and the misunderstandings that used to occur, streamlining the process. 

The IBAN code in detail

The IBAN is an alphanumeric code (numbers and letters) consisting of two separate parts: 

  • 4 initial characters: the first two are the country code, while the other two are the control code. For example, ES-61.
  • Customer account number: it also consists of a series of 20 digits that make it up. Each part also has an explanation. In this case, let's take the number 1234 3456 42 0456323532 as an example.
    • The first four correspond to a bank (1234).
    • The next four correspond to a branch (3456).
    • The next two are the control digit (42).
    • Finally, the last ten correspond to a bank account (0456323532).

As a result, the complete IBAN code consists of 24 characters in Spain and in this case, it would be as follows: ES61 1234 3456 42 0456323532. However, in other countries, it can be as long as 32 characters.

It's important not to confuse the IBAN with the BIC, a code of 8 to 11 characters that is used to identify the bank that receives a transfer (also called destination). Although the two concepts are normally used in different processes, they are not the same.

Applications of the IBAN code: the SEPA

After the entry into force of the euro (2002), the EU achieved its goal of having a common currency. However, there were still problems with some monetary transactions. Each Member State still had its own bank accounts and when it came to transferring money, it was difficult to know what country it came from. To simplify things, the EU launched SEPA (Single Euro Payments Area) in 2014. 

The 27 EU member states, as well as Iceland, Liechtenstein, Monaco, Norway, San Marino, Switzerland, Andorra, Vatican and the United Kingdom (despite Brexit) belong to it. In general, the coverage does not extend to the overseas territories of countries such as France, the United Kingdom or the Netherlands. And in Cyprus, only the part controlled by Northern Cyprus is included.

In parallel to the emergence of this new financial region, the IBAN code was introduced in bank accounts in order to replace the previous Bank Account Code (CCC). In the case of Spain, accounts had 20 digits previously. With this new change, and as mentioned earlier, they all transitioned to 24, starting on 1 February 2014. The other Member States also went through similar processes. The last step occurred in 2016, when the deadline for countries outside the eurozone to migrate to this SEPA system expired. 

The applications of this single euro payments area extend to several sectors. These include transfers, direct debits and cards. In this regard, the advantage for Spaniards is clear: they can make transfers to any SEPA country faster.

IBAN in countries without SEPA

The IBAN code is used beyond the SEPA. More than 80 territories in the world are currently required to use this system. These include Kazakhstan, Lebanon and Kuwait. In others, such as Iran, Brazil and the Dominican Republic, its use is recommended. This number will probably go up in the future, since the IBAN provides a fast and easy way to identify bank accounts worldwide.
