From time to time, tools like Bizum arrive that manage to make our lives much easier. Through our telephone number, Bizum allows us to both send and receive money in a matter of seconds in our bank account. This service is easy to use, but it has particularities that you may not know, such as, for example, if it is possible to have two numbers with the same Bizum . If you don’t know the answer, we will tell you in this article.
As we say, the arrival of Bizum has been a breakthrough in terms of personal finances . Today, most people have this service active and, in fact, it is already possible to pay in many stores or businesses with this payment method.

Bizum only allows one IBAN per number
Lets start by the beginning. To register with Bizum, we will have to do it through our online banking application, which will be different, obviously, depending on our bank. Doing it is very simple, since all we have to do is find the section where it says Bizum or Send/Receive money and accept the Terms and Conditions of the service . Once this is done, we will have the possibility of making Bizum without having to wait for some type of authorization or similar to arrive.
What this process does is link a phone number to your IBAN , so that when you send or receive money with your mobile, you will be doing it through this account. The best thing about Bizum is that it is a totally free tool that can be used by everyone, and it only requires you to have a bank account and be of legal age in practically all the banking entities in our country.
Now, is it possible to join another phone number to the same IBAN? Well yes, yes it can. As the Bizum Frequently Asked Questions page explains, it is possible that the same Bizum account has two associated telephone numbers . Now, what is not possible is to have the same phone number associated with more than one bank account. If you have two bank accounts and your phone number associated with one, you won’t be able to associate it with the other as well without unsubscribing first.

How do we unsubscribe?
If your case is the latter that we have mentioned, you must first unsubscribe from the Bizum service before registering with your second bank account. To do this, we will have three different ways that we can use equally for it. The first and most direct is to do it through the same online banking that we have used to register. In the same Bizum section you should find a button that allows us to limit the service or unsubscribe, something for which it will probably ask us for some type of credential such as a digital signature.
Another channel that we can use to unsubscribe is the customer service of our bank. This usually has several ways to connect with him, either by call, email or through online banking through a chat. Finally, we also have the possibility of approaching our bank so that they can help us or advise us to permanently unsubscribe. When we have done it, we will only have to go to our second bank account and do the same process as before to register Bizum.
