Las empresas deben usar una numeración específica para identificar las llamadas comerciales desde este 17 de octubre, mientras que los consumidores pueden pedir a su operadora que bloquee estos contactos
In Spain, commercial calls will have a new identifier from Saturday, 17 October, as they will be required to use the prefix 400. Companies making calls to offer products, promote services or attract new customers will have to use numbers starting with these three digits. The aim is to allow consumers to recognise commercial calls before answering and decide whether to take the call.
