400 Number Requirements in Spain — Commercial Outbound Calls
Please Note: From 17 October 2026, all commercial outbound calls in Spain must be made from a number in the 400 range, as required by the Spanish telecommunications regulator (CNMC).
Who must comply
The following sectors must comply regardless of company size: utilities (water, gas, electricity), telecommunications, financial services (banking, insurance), and transport and postal services. Companies in other sectors must comply if they have more than 250 employees, more than €50M annual turnover, or more than €43M balance sheet total. Customer retention, renewal, and loyalty calls are considered commercial calls.
How 400 numbers work
400 numbers are outbound-only and cannot receive incoming calls. Each customer is allocated one 400 number. All commercial outbound calls must be made from this number. Existing geographic numbers can continue to be used for inbound calls and non-commercial outbound calls.
From 17 October 2026, operators are entitled to block any commercial call that does not originate from the 400 range.
How to order
Place your order via the LeadApps Store. Orders must be submitted by someone within your organisation. For questions, contact your LeadDesk Account Manager.
