What changed
Alongside the commercial call numbering rule, Spain has reserved a separate telephone number range specifically for customer service lines (after-sales support, complaints, and incidents), keeping them clearly distinct from commercial calls. Companies subject to the 2025 Customer Service Act must use this dedicated numbering for support lines.
Who is affected
Directly affects companies required by law to offer customer service lines, especially those covered by the 2025 Customer Service Act. For consumers, it means they can easily tell whether they are calling a genuine support line or a commercial sales number.
What to look out for
→ No action required from consumers. Companies with legal customer service obligations should verify their current numbering and adapt to the new requirements within the deadlines set by implementing regulations.
