Abstract
An emergency route back number (ERBN) may be assigned for use in emergency calls. A telecommunication network associated that may be associated with a wireless service provider, may identify an emergency call directed to an emergency number (e.g., 9-1-1) that originated from a device that is not associated with a unique phone number such as a shared line, or a communication that utilizes some other indicator to establish the emergency call (e.g., an email address, or some other identifier). When an emergency call is detected that does not have a dedicated phone number, an ERBN is assigned to the communication. This ERBN may be reserved for some period of time after the emergency call ends such that emergency contact centers are able to reach callers back in case of dropped calls, fails, and/or additional emergency services that may need to reach the callers directly.
