Marigold has a long history of helping Telecom companies with innovative Direct Marketing programs. Today we are happy to announce that all of our extensive list properties are selectable by Central Office or CLLI code. A Central Office is essentially a building where Telecom companies house their switches and hubs. What this means is that Telecom companies can target consumers or businesses based on where the Telecom company has facilities.
Marigold can target businesses or consumers within a specific radius of a Central Office where, for example, DSL equipment has been installed. When a DSL provider invests in their network and offers new services in a new market, they want to maximize that investment by signing up customers in the area that can be serviced by that new DSL switch. Marigold works closely with our Telecom clients to get the best return on investment possible in the Direct Marketing arena.
Here are some basic counts on the most populated Central Offices according to our database:
