What Is Routing & Network Data?

Routing & Network Data refers to the datasets used to determine how calls are directed through telecom networks and which carriers are responsible for handling them.

These datasets include Local Routing Numbers (LRN), LERG (Local Exchange Routing Guide), and other forms of network intelligence that identify where a number resides and how calls should be routed.

For voice providers, this data is essential to ensuring that calls are delivered accurately, attributed correctly, and handled in accordance with network and regulatory requirements.

How It Works

When a call is initiated, routing data is used to determine the appropriate destination and the network path required to complete the call.

LRN data identifies the current serving switch for a telephone number, while LERG data provides broader routing and carrier information. Together, these datasets help providers:

Route calls to the correct destination
Identify the underlying carrier responsible for a number
Support interconnection and network handoffs
Maintain accurate call handling across complex telecom environments

This information is applied during call setup and routing processes, ensuring that calls move efficiently and correctly through the network.

Why It Matters

Accurate routing is foundational to both network performance and compliance.

Without reliable routing data, providers risk:

Misrouted or failed calls
Incorrect carrier attribution
Operational inefficiencies
Challenges responding to regulatory inquiries or traceback requests

Routing & Network Data ensures that calls are handled correctly from the start, reducing errors and supporting more reliable network operations.

It also plays a role in compliance by helping providers demonstrate how calls are routed and which parties are involved in call handling.

Common Use Cases

Routing & Network Data supports a wide range of telecom operations, including:

Determining the correct routing path for outbound and inbound calls
Identifying the current carrier associated with a telephone number
Supporting intercarrier agreements and traffic exchange
Enabling accurate billing and network reporting
Assisting with traceback and regulatory response efforts

These use cases help ensure that networks operate efficiently and transparently.

Who It’s For

Routing & Network Data is essential for organizations responsible for managing or operating telecom traffic, including:

VoIP providers
Telecom carriers
UCaaS platforms
Managed service providers
Enterprises managing voice infrastructure

Any organization routing or handling call traffic benefits from accurate and up-to-date network data.

Part of a Larger Compliance Framework

Routing & Network Data is a core component of telecom infrastructure and works alongside other systems to support compliant operations.

It integrates with:

Compliance data controls (DNO, DNC)
Caller identity and authentication systems
Real-time call governance tools
Fraud monitoring systems

Together, these elements provide a complete view of call handling, from origination and identity to routing and monitoring.
