Order TDF/149/2025: make calls and send SMS from your company

Does your company comply with the new call and SMS regulations? If your company uses commercial calls, customer service or SMS, it is essential that you adapt your communications to the new regulations governing the identification and use of telephony and messaging in Spain.

The Order TDF/149/2025promoted by the Ministry for Digital Transformation and the Civil Service, seeks to reduce telephone fraud, protect users and restore confidence in business communications.

If your company does not adapt, you could face blockages in your calls and messages, affecting the relationship with your customers.

In this article, we explain what you need to take into account to ensure that your communications comply with the regulations and how in Gloferaas a telecommunications operator, we can help you to ensure the continuity and security of your business communications.

What should commercial and customer service calls look like to comply with Order TDF/149/2025?

If your company makes commercial calls or manages a customer service department, it is essential to adapt the numbering you use.

  • The use of mobile numbers for commercial calls or customer service is prohibited. Companies must use fixed numbers or numbers in the 800 and 900 ranges.

  • If you call a customer, the number must be identifiable and legitimate. Do not use hidden or manipulated identifiers; calls with empty CLI will be blocked.

  • Allow customers to return calls free of charge. The use of 800 and 900 numbers to return calls at no cost is authorized.

How to adapt to the new order TDF/149/2025?

If you use a mobile number to manage business calls or customer service, you need to migrate to an IP telephony solution with fixed or free numbering. Glofera can help you configure your virtual PBX to comply with regulations without losing efficiency in your communications.

What should SMS/MMS messages look like to comply with regulations?

If your SME sends text messages (SMS/MMS/RCS) to customers, you must ensure that the numbers used are verified and registered correctly.

  • Do not use unregistered or manipulated numbers. Operators will block messages with empty CLI or unauthorized numbers.

  • If you use an alias or trade name in SMS, it must be registered with the CNMC. All companies that send messages with alphanumeric identifiers (aliases) must register them in the Registry of the National Commission of Markets and Competition (CNMC).

  • Avoid using international numbers to send commercial messages. Operators will block SMS originating abroad if they present an unauthorized Spanish CLI.

If your company uses commercial or customer service SMS, make sure you work with an operator that guarantees regulatory compliance. At Glofera we offer secure solutions for sending bulk and verified SMS.
