What is the IMEI Registration & TAC Approval? Difference Between

In today’s mobile-driven world, every smartphone, tablet, or cellular device carries a unique identity known as the IMEI number. This number plays a crucial role in identifying and authenticating mobile devices across global telecom networks. In India, to ensure the legal import, sale, and traceability of mobile devices, IMEI registration and TAC approval have become mandatory steps. Let’s understand what these processes are, how they differ, and why they are important.

What is IMEI Registration?

The International Mobile Equipment Identity (IMEI) is a 15-digit unique code assigned to each mobile device. The process of IMEI registration ensures that the IMEI number of every device is officially recorded in the Indian CEIR (Central Equipment Identity Register) managed by the Department of Telecommunications (DoT) through the CDOT (Centre for Development of Telematics).

When a manufacturer or importer brings a new mobile model to India, they must register the IMEI number on the CDOT IMEI portal. This step creates a verified database of devices that are authorized for sale and use in India.

Steps to Register IMEI Number

To register IMEI numbers in India, the following process is followed:

1. TAC Approval: Before IMEI generation, the manufacturer must obtain a Type Allocation Code (TAC).

2. IMEI Number Generation: Using the TAC, unique IMEI numbers are generated for each device unit.

3. IMEI Upload: The manufacturer or importer uploads all IMEI numbers on the official IMEI registration portal.

4. Verification and Approval: Once verified, the devices are marked as legally registered and can be imported or sold in India.

5. Issuance of IMEI Certificate: After successful registration, an official IMEI certificate is issued confirming that the devices are registered and verified.

This IMEI certificate acts as proof of authenticity for customs clearance, import, and product sale authorization.

What is TAC Approval?

TAC (Type Allocation Code) is an essential component of the IMEI number — the first eight digits that identify the brand, model, and manufacturer of a device. TAC approval ensures that each device model has a unique identity in the global database, preventing duplication or misuse.

The TAC approval is granted through CDOT in India, based on international guidelines. Manufacturers or importers must provide detailed technical information, brand details, and test reports for approval. Once TAC is granted, it serves as the foundation for generating valid IMEI numbers.

Difference Between IMEI Registration and TAC Approval

In simple terms, TAC approval identifies what the model is, while IMEI registration identifies each unit of that model.

Why IMEI Registration is Important

• Ensures legal sale and distribution of mobile devices in India.

• Helps track and block stolen or duplicate devices.

• Required for import and customs clearance.

• Builds consumer trust by guaranteeing product authenticity.

• Mandatory compliance under DoT and CEIR regulations.

Conclusion

Both TAC approval and IMEI registration are crucial for mobile device compliance in India. Without TAC approval, IMEI numbers cannot be generated, and without IMEI registration, devices cannot be legally imported or sold.

So, whether you are a mobile manufacturer, importer, or distributor, it’s essential to register IMEI numbers and obtain your IMEI certificate to ensure full regulatory compliance. Proper registration not only supports lawful operations but also enhances consumer safety and trust in your products.
