TAC APPROVAL & IMEI REGISTRATION

Introduction

TAC and IMEI - Overview

Definition and Overview of TAC: The Type Allocation Code (TAC) is an essential element in the mobile industry, representing the first eight digits of the International Mobile Equipment Identity (IMEI) number. Each mobile device requires a unique TAC to be assigned by the Global System for Mobile Communications Association (GSMA) , which ensures the device is recognized on global networks. TAC allows brand owners to differentiate between various models and manufacturing variations, facilitating global trade and device management.

Definition of IMEI and Its Purpose

The IMEI (International Mobile Equipment Identity) number is a 15-digit identifier unique to each mobile device. It is crucial for tracking, device management, and preventing theft or loss. When paired with a TAC, the IMEI offers mobile service providers and regulatory authorities a reliable tool for monitoring and regulating devices.

IMEI registration in India is the process of registering the unique International Mobile Equipment Identity (IMEI) numbers of mobile devices with the Central Equipment Identity Register (CEIR), managed by the Department of Telecommunications (DoT). This registration is essential for ensuring the traceability, authenticity, and security of mobile phones, helping to prevent theft and fraud. By maintaining a comprehensive database of all IMEI numbers, authorities can block stolen devices from accessing mobile networks and aid in their recovery. The process involves manufacturers and importers submitting detailed information and documentation to obtain certification and integrate IMEI numbers into the national registry.

What is TAC (Type Allocation Code)

The TAC is a unique identifier assigned to a specific mobile device model by GSMA-certified bodies. This code is vital for enabling cellular network connectivity and ensuring compliance with international standards. Every mobile device connecting to a 3GPP or 3GPP2 network needs a TAC. TAC not only ensures the authenticity of a device but also aids in global trade by allowing governments and organizations to track legitimate devices, preventing the circulation of counterfeit goods. By associating a TAC with a specific model, mobile operators can accurately serve devices on their networks and track their usage.

The GSMA, an industry body that governs global telecommunications standards, allocates TAC codes through authorized reporting bodies. Each brand owner must apply for a TAC to have their device recognized and authenticated across global networks. The GSMA ensures that these codes are distributed fairly and according to regulatory guidelines.

Key Elements of TAC Allocation

TAC Structure (8-digit format): The TAC code is the first 8 digits of the 15-digit IMEI number. The structure includes information about the manufacturer, brand, and device model. These digits are crucial for identifying each device uniquely, and they serve as the foundation for generating the complete IMEI.

TAC for Multiple Models and Variants: A single TAC is assigned to each unique device model. If there are any significant changes to the model, such as hardware upgrades or component modifications, a new TAC must be obtained.

Frequency of New TAC Allocation: A new TAC is required once a model reaches one million units. This ensures that each batch of devices remains easily identifiable by its TAC, preventing duplication and aiding in efficient tracking.

TAC Reporting and Application Process

GSMA-Approved Reporting Bodies: To maintain compliance, brand owners must apply for TAC through GSMA-authorized reporting bodies. Depending on the location of the brand's headquarters, the appropriate reporting body will manage the application. For example, TUV SUD is the reporting body for most regions, except China, where TAF handles the process.

Requirements for Brand Owners and OEMs: The brand owner holds the TAC, while the original equipment manufacturer (OEM) is named in the application. The application must specify the brand, the model, and details about the manufacturer to ensure proper allocation.

TAC Application Process Explained: The process begins with the brand owner submitting an application to the relevant reporting body. After verifying the details, including device specifications and production capacity, the TAC is allocated. Once approved, the brand owner can produce devices using the assigned TAC.

Variations That Require a New TAC

Changes in Brand, Manufacturer, or Model: If there is any change in the brand owner, OEM, or model name, a new TAC must be applied for. These changes affect the device's identity, which requires updated tracking.

Hardware Modifications: Changes in the device’s hardware, such as the motherboard, chipset, or number of cameras, require a new TAC. This ensures each unique model variant has its own identifier.

Software and Operating System Changes: If a device undergoes a major change in its operating system, such as switching from Android to Tizen, a new TAC is necessary to reflect these modifications accurately.

What is an IMEI Number?

An IMEI number is a unique 15-digit identifier assigned to every mobile device, including 3GPP and iDEN phones, as well as some satellite phones. This number is crucial for identifying and tracking mobile phones globally. Typically, the IMEI number can be found printed inside the phone's battery compartment or displayed on-screen by entering *#06#* on the dial pad. The IMEI is used for various security and network functions, including blocking stolen devices from accessing mobile networks and assisting in their recovery, thereby playing a key role in preventing mobile phone theft and fraud.

Scope for IMEI Registration

The scope for IMEI registration in India encompasses both manufacturers and importers of mobile devices, ensuring that every device entering the market is uniquely identifiable and compliant with regulatory standards.

Manufacturers

Every mobile equipment manufacturer or brand owner must register their devices with the GSMA IMEI database. This involves obtaining an IMEI registration certificate verifying that devices are assigned unique IMEI numbers that comply with international standards. This ensures devices can be accurately tracked and identified, providing security and authenticity.

Importers

Importers of mobile equipment must register their devices to ensure compliance with regulatory requirements. They submit an application via the online portal, providing detailed device specifications. The GSMA ICDR system validates the information, and once approved, a registration certificate is issued, allowing import of mobile equipment.

Benefits of IMEI Registration

IMEI registration offers numerous advantages that enhance the security, traceability, and regulatory compliance of mobile devices. Key benefits include:

Prevention of Theft and Fraud

Registered IMEI numbers allow mobile network operators to track and block stolen devices, reducing mobile phone theft and fraud. Law enforcement agencies can use the IMEI number to locate stolen devices.

Device Authentication

IMEI registration helps verify the authenticity of devices, ensuring only genuine and compliant devices are used on mobile networks.

Network Security

Registered IMEI numbers maintain network integrity by preventing unauthorized devices from accessing network services, ensuring compliance with international and national standards.

Regulatory Compliance

Facilitates legal importation of mobile devices, ensuring all devices comply with regulations. Simplifies customs clearance for smoother processing.

Consumer Protection

Provides transparency, helping consumers make informed choices and protecting them from counterfeit or non-compliant devices.

Market Integrity

Promotes standardization across the mobile device industry, ensuring consistency in device identification and traceability.

Support for Investigative Agencies

Assists agencies in tracking criminals by monitoring IMEI numbers and provides data for investigations and legal proceedings.

Facilitating Consumer Self-Registration

Allows consumers to register their devices independently, providing control over device security. Registered IMEIs can be quickly reported and blocked in case of loss or theft.

Step-by-Step Process for IMEI Registration in India

The process for registering an IMEI number in India ensures that all mobile devices are uniquely identifiable and compliant with regulatory standards.

Step 1: Application Submission: Register on the official IMEI portal using a user ID. Fill out the form with company details and submit required documents such as Certificate of Incorporation, business licenses, etc.

Step 2: Document Inspection: Authorities review and validate the submitted documents for compliance and authenticity.
