TAC Type Allocation Code

Last updated on 

Introduction

In the context of mobile telecommunications, the Type Allocation Code (TAC) is a unique identifier assigned to each mobile device model. The TAC is used to identify the device's manufacturer, model, and other essential information. It plays a crucial role in device management, regulatory compliance, and network operations.

Functionality

The primary function of the Type Allocation Code is to provide a globally unique identifier for each mobile device model. The TAC is assigned by the GSM Association (GSMA), an industry organization that oversees the development and implementation of mobile communication standards. The TAC is part of the International Mobile Equipment Identity (IMEI) number, which uniquely identifies each individual mobile device.

Structure of Type Allocation Code

The Type Allocation Code consists of eight digits and has a specific structure:

  • The first two digits of the TAC represent the Reporting Body Identifier (RBI), which identifies the organization responsible for allocating TACs. The RBI is assigned by the GSMA.
  • The remaining six digits of the TAC represent the Manufacturer Identifier (MID), which identifies the specific manufacturer and device model.

The combination of the RBI and MID creates a unique TAC for each device model.

Usage and Significance

The Type Allocation Code has several important applications within the mobile telecommunications industry:

  1. Device Identification: The TAC is used to identify each mobile device model. It provides information about the device manufacturer, model, and other relevant details. The TAC is part of the IMEI, which is a fundamental identifier used by network operators, device manufacturers, and regulatory bodies.
  2. Regulatory Compliance: The TAC is utilized by regulatory authorities to ensure compliance with local regulations, such as device certification and type approval. By analyzing the TAC, regulators can verify that the device being used meets specific technical and legal requirements.
  3. Device Management and Inventory: The TAC is essential for device management and inventory purposes. Network operators and device manufacturers use the TAC to keep track of device models, their distribution, and their compatibility with network technologies and services.
  4. Network Operations: The TAC is used by network operators for network planning, optimization, and troubleshooting. By analyzing the TAC, operators can gain insights into the types of devices connected to their networks, identify compatibility issues, and optimize network resources accordingly.
  5. Security and Fraud Prevention: The TAC is a valuable tool for security and fraud prevention. By analyzing the TAC, network operators can identify and track devices involved in illegal activities, such as device theft, unauthorized device modifications, or fraudulent activities on the network.

Conclusion

The Type Allocation Code (TAC) is a unique identifier assigned to each mobile device model. It provides valuable information about the device manufacturer, model, and other details. The TAC is an integral part of the International Mobile Equipment Identity (IMEI) number and plays a significant role in device management, regulatory compliance, network operations, security, and fraud prevention. By leveraging the TAC, network operators, device manufacturers, and regulatory bodies can ensure proper device identification, maintain regulatory compliance, optimize network operations, and enhance security measures within the mobile telecommunications industry.
