Banning commercial calls: how to adapt

The ban on commercial calls is putting many SMEs in check: the sales team wants to continue calling from their mobile, but the fear of blockages, complaints and lost opportunities is real. The good news is that the rule is not about “don’t call”, but about calling with correct identification and proper numbering, to reduce scams and spam (yes: you can still work on mobile, but with the right approach).

At Glofera we work every day with companies that need a practical, legal and practical, legal and hassle-free solution: to keep sales reps on the move and, at the same time, to comply with and, at the same time, comply with regulations and offer a professional image. Our way of doing it usually goes through a very simple idea: mobile yes… mobile numbering no when we talk about unsolicited commercial calls or customer service calls affected by the Order TDF/149/2025

What does the ban on commercial calls from cell phones mean?

The key is to understand the “why”. Order TDF/149/2025 was created to stop frauds that rely on caller ID manipulation (technically known as CLI, the number you see on the screen). The objective is that the user can better identify who is calling and that operators can block irregular communications: unassigned numbers, “false” numbers, calls that appear to be from Spain when they really originate outside of Spain, etc.

In practice, for many companies the most visible impact is this: as of June 7, 2025, mobile numbers (prefixes 6 and 7) cannot be used to make certain unsolicited commercial calls (and, according to interpretations and guides, it also affects certain customer service scenarios). Therefore, even if your salesperson is calling with all the good intentions in the world, if he/she is “showing” a cell phone, the user perceives it as spam and operators have more and more mechanisms to filter it out.

“So do I have to stop campaigns? Do I have to change mobiles? Do I lose the number I’ve had all my life? No. What changes is the way the call is presented and the type of numbering from which it is issued. Instead of showing a cell phone, the usual solution is for the call to be identified with a geographic number (91, 93…) or with 800/900, or with correctly assigned/authorized numbering. This, in addition to helping compliance, improves customer confidence: a recognizable and consistent number has a higher response rate than an “unknown” mobile.

In Glofera we always explain it with an example: the salesperson wants to call from the car, from a visit or from home. Perfect. But instead of “calling with his 6XX”, he calls with the app/softphone and the customer sees the company’s landline number or the 800/900 of the campaign. The salesperson still uses his cell phone, but the company complies and keeps control (recording, statistics, queues, diversions, etc.). That is the difference between “prohibition” and “intelligent adaptation”.

When did TDF 149 2025 become effective?

This standard has been implemented in phases (and this is where many companies get confused, because they mix up dates):

• February 15, 2025: publication in BOE of Order TDF/149/2025 (of February 12).
• March 7, 2025: start of blocking measures related to irregular/unassigned numbering and part of the anti-fraud plan (operators start to leak more strongly).
• June 7, 2025: key milestone for companies: restrictions/impediments to the use of mobile numbers for unsolicited commercial calls (and general reinforcement of the blocking of irregular calls).
• June 7, 2026: additional measures linked to messaging (aliases/identifiers) and other mechanisms to strengthen traceability (e.g., registration/management of aliases within the framework indicated by the standard).

What does this mean for your company? That it is not worth waiting for the “storm to pass”. Since 2025, filtering and blocking have been on the rise. And this is not just about compliance: if your customers associate your calls with spam, your conversion drops even if you are not formally blocked.

In addition, new complementary measures are being announced in 2026 to facilitate the identification of commercial calls, such as the 400 prefix prefix (planned for late summer 2026). In other words: the regulatory and operational context is moving towards more transparency and more call origin signaling.

When an SME tells us “we need to continue selling by phone”, our recommendation is simple: set up a Virtual PBX (fixed number/800/900), centralize the management and do not depend on “each mobile on its own”. Not only you reduce risk: you also increase the level of customer service and internal control.

What numbers can you use to legally call customers?

If your goal is to continue to make business calls (and do it well), think about numbering that the customer will identify and that fits the rules. In practice, these are the most common options cited as valid/appropriate in industry guides and summaries of the standard:

1) Geographic numbering (91, 93, 96…)

It is the most natural for many SMEs, because it conveys “local business” or “established business”. It also conveys “local company” or “established company”:

• Improved response rate (people are less suspicious than with an unknown cell phone).
• Provides continuity: you always call with the same number and the customer can call you back on the correct channel.

2) 800 and 900 numbering

It tends to work very well in campaigns or attention, because it also reduces friction:

• “If I call back, does it cost me?” At 800/900 the perception is kinder.
• It is useful for campaigns that want transparency and ease of callback.

3) Correctly assigned/authorized numbering

This includes everything that is “well provisioned numbering” by operator/supplier and not “rare”, unassigned or manipulated numbering. The focus of the Order is precisely to avoid irregularity and impersonation.

What is not convenient (and less and less) is to “pull” with mobile numbers for unsolicited commercial calls or affected scenarios, because it puts you in the same mental bag as spam and exposes you to filtering.

How to continue calling from the mobile without skipping the TDF/149/2025 order?

Mobile yes, mobile numbering no (in the context concerned), the commercial still uses the mobile as a device. But the call goes out identified with fixed/geographic or 800/900 numbering. The company controls the operation from a Virtual PBX.

This, in practice, translates into 3 simple changes:

1. Unify the outgoing number: no more calling “each to his own number”. A corporate number (or several per site/department) is defined.
2. Give the team an easy way to call: App/softphone or simple integration so that the salesperson does not notice friction.
3. Create a professional service circuit: If they don’t pick up, they go to the queue; if it’s after hours, a voice mail; if it’s important, a diversion; if necessary, a mailbox. And everything measurable.

This not only helps with compliance and perception: it improves sales because you reduce missed calls and increase consistency. Improvements are clear when the circuit is ordered (and that’s why we talk about productivity, attention and control, not just “compliance”).

If your business sells or services over the phone, this regulation is not an obstacle, it’s a perfect excuse to do things better. Professionalizing your calls, measuring what really matters and conveying more confidence doesn’t just help you comply with the law. It helps you sell better.
