Associating unique identifiers of primary and enriching content

A system comprising:

• a Unified Numbering System (UNS) server configured to:
• associate a first UNS identifier with a primary media content item, wherein the first UNS identifier is selected from a set of unique identifiers;
• associate at least one second UNS identifier with at least one enrichment content item, wherein the at least one second UNS identifier is selected from the set of unique identifiers;
• an enhancement database configured to establish an indirect link between the primary media content item and the at least one enrichment content item by storing a relational entry linking the at least one second UNS identifier with the first UNS identifier;
• and
• a communications interface configured to provide the at least one enrichment content item to a subscriber based on the indirect link.

A Unified Numbering System (UNS) server, the UNS server comprising:

• a processor;
• a memory operably coupled to the processor;
• a non-transitory program of instructions configured to be stored in the memory and executed by the processor, the program of instructions including:
• at least one instruction to associate a first UNS identifier with a primary media content item, wherein the first UNS identifier is selected from a set of unique identifiers;
• at least one instruction to associate at least one second UNS identifier with at least one enrichment content item, wherein the at least one second UNS identifier is selected from the set of unique identifiers;
• at least one instruction to establish an indirect link between the primary media content item and the at least one enrichment content item by storing a relational entry linking the at least one second UNS identifier with the first UNS identifier;
• and
• at least one instruction to provide the at least one enrichment content item to a subscriber based on the indirect link.
