The ban on marketing calls outside permitted hours helps ensure you can enjoy your time off. We will only call you during business hours and never on public holidays or weekends.
We don’t call you just to present you with new proposals. We contact you to inform you about exclusive offers, benefits and improvements designed to make daily life easier.
We support the ban on spam calls. That is why we will present our offers clearly and transparently, so you can consider them without pressure and in complete confidence.
It means that a company is trying to get in touch with you to send you a commercial communication. Under the new law on marketing calls, the Government has assigned this specific prefix to provide greater transparency and allow you to identify the reason for the call instantly on your screen before answering.
At CaixaBank Payments & Consumer, we use these official numbers for our marketing communications. By using the 400 prefix, we strictly comply with the regulation on marketing calls and ensure that you can clearly, quickly and transparently identify that we are the ones calling you.
Yes, it is completely safe to answer it. The creation of this special numbering system is specifically intended to combat nuisance calls and banking fraud. For your complete peace of mind, the full, up-to-date list of our authorised numbers is available on this official website, so you can carry out any checks you need.
It’s very simple. Simply visit this website and check our official list of telephone numbers with the 400 prefix. If the number shown on your mobile phone matches one of the numbers on our list, you can be absolutely certain that you are speaking to CaixaBank Payments & Consumer securely.
Although the ban on anonymous marketing calls provides users with a high degree of protection, fraudsters are always looking for new ways to operate.
So if you have any concerns, remember our golden rule: CaixaBank Payments & Consumer will never ask you for secret passwords, access credentials or signing codes over the phone. If you are asked for this personal information, hang up immediately and verify the telephone number with us.
No. For security and regulatory reasons, these official numbers are configured exclusively to make outgoing calls and do not accept incoming calls. If you try to call back, your phone will not give you a dial tone or will indicate that the number does not exist. This helps prevent you from falling victim to scams such as suspicious missed calls.
With the new law on marketing calls now in force, the use of conventional mobile or landline numbers for advertising campaigns is restricted. The aim of regulating the sector is to put an end to prohibited or unknown source marketing calls, requiring legitimate organisations to clearly identify themselves to consumers at all times.
Your peace of mind is our priority, and we fully respect your decisions. Although the law provides for a ban on marketing calls without prior consent, if you ever wish to withdraw your authorisation for us to inform you about new products or exclusive offers, you can do so quickly and easily through your private customer area (on the website or official app) or by contacting our Customer Service.
