Until now, it was common to receive commercial calls from mobile numbers, something companies use to increase their response rates. But that is now over.
Since June 7, 2025, a new regulation has come into effect in Spain that prohibits making commercial calls from mobile numbers. This measure was introduced to protect users from phone fraud, scams, and commercial spam, which have become increasingly common.
The new rule aims to improve transparency in communications, making it clear that companies must use clearly identifiable numbers suitable for commercial purposes. This change greatly affects those who make large volumes of calls, who now need to adapt to this legal framework.
Looking on the bright side, this regulation represents an opportunity for companies to update and professionalize the way they communicate with their customers. This is where Megacall stands out as a solution that adapts to this new scenario, offering
virtual landline numbers and tools designed for teams handling large call volumes.
What are the changes with this new regulation?
- Prohibition of commercial calls from mobile numbers.
It is no longer allowed to use mobile numbers to make commercial calls. Companies that do not comply with this new regulation may face hefty fines, as it would be considered a serious offense.
- Only official numbers can be used.
From now on, companies can only make calls from:
- Geographic landline numbers (such as provincial prefixes 91, 93, etc.)
- Numbers starting with 800 or 900. These numbers are suitable for customers to contact the company as they allow toll-free calls.
- Special numbers like Movistar’s 1004.
Commercial calls from mobile numbers will only be permitted if the customer has given prior consent, for example, by accepting the use of their data to receive offers.
- Blocking of suspicious calls.
Operators are required to automatically block all calls and SMS that violate these rules, as well as international calls that impersonate a Spanish number.
How can companies adapt to the new commercial calling regulations?
Companies making large volumes of calls can no longer rely on mobile numbers for commercial calls,
but there are legal alternatives such as landline numbers.
With virtual number providers like Megacall, companies can continue running their campaigns with customers legally and professionally, thanks to virtual landline numbers. So, what options do we have under this new regulation?
Megacall geographic landline numbers
At Megacall, you can get numbers from different locations with the prefix you choose (Madrid, Barcelona, Valencia, etc.). This provides a more professional image than a mobile number and also complies with current regulations for commercial calls.
Even though it’s a landline number, you can carry your number on your mobile thanks to the Megacall app. This way, you can make and receive calls from your mobile anywhere. Available for Android and iOS.
Additionally, it’s possible to connect the number to
Megacall’s virtual PBX, enabling more organized communication with features like call recording, transfers, voice recognition, and even integration with artificial intelligence to offer better customer service.
800 or 900 numbers
Numbers starting with 800 or 900 are toll-free for the caller and can also be used for commercial calls where the company bears the cost. These numbers are great for companies that want to strengthen their service image since customers will recognize it as a company call. They’re useful for sectors aiming to show transparency, such as insurance companies, banks, etc.
We can see that the advantages of Megacall’s geographic landline numbers are much more significant than using a mobile number. First and foremost, it’s completely legal—something mobile numbers are no longer allowed for without prior consumer consent. Additionally, it gives a much more professional image and is fully scalable for large call volumes.
It’s about generating trust from the first ring. That requires clear numbering and flexible tools. This is an opportunity to reconsider how we communicate with customers and which tools we use for it. Therefore, if you haven’t adapted to this new regulation yet, now is the time to switch to solutions that not only comply with the law but can also scale according to your business needs, like Megacall, which offers a wide variety of numbers and can manage large volumes of calls without losing quality or control.
