Facilitation of management and utilization of domain-specific anonymous customer references (ACRs) for protection of subscriber privacy across different domains is disclosed herein. In one aspect, on receiving user authorization, an ACR services (ACRS) component can generate an ACR that is to be inserted in a communication or message transmitted from a user equipment to an untrusted entity. The ACR can be generated based on address data associated with the untrusted entity and/or a unique subscriber identifier associated with the user equipment. As an example, the ACR creation component can generate the ACR based on a cryptographic hash, a static encryption key, and/or a dynamic encryption key. If the ACR is forwarded to a trusted entity, the trusted entity can calculate the unique subscriber identifier based on evaluating the ACR and/or exchange the ACR for the unique subscriber identifier via a secure communication with the ACRS component.
