Code sharing is a voice service accessed via the Eutelia Carrier Selection 10062. It is dedicated to provision of wholesale services to companies that resell phone traffic; despite they have no infrastructure ("Switchless Reseller"). Reseller enables Calling Line Identifiers (CLI, aka phone numbers) of its end Customers by entering them to an appropriate webpage. Registered CLIs can now access service by dialling the 10062 carrier selection code before the number being called. The Eutelia network, after checking the calling line corresponds to an enabled CLI, manages the call up to its final destination. Code can be entered on a keypad or by a device for automatic routing (dialler or smart box) managed by Reseller.

As an alternative, Eutelia can provide Code Sharing together with "Carrier Pre-Selection" (CPS): in this way, any call by a CPS-enabled CLI is automatically routed to the Eutelia network with no need for dialling 10062 first. Troubles from automatic routing devices are thus avoided and no call goes lost just because user had forgotten to dial 10062 first. Even when CPS is on, an operator, other then the selected default one, can be invoked by dialling that operator’s selection code first.

Eutelia provides the Reseller with an interface to allow autonomous management of service, by self-provisioning of CLIs (activation/deactivation/suspension); it also provides with daily retrieval of call details records (also in ‘put’ mode by automatic forwarding of file to an IP address specified by customer), outages notices with trouble ticket tracing, download of invoice duplicates in .pdf format, etc...
