Need to apply for TAC?<\/h2>\n\n\n\n

3GPP requires all device types that can connect to a mobile wireless network to be identifiable by a Type Allocation Code (TAC), including IoT devices, payment terminals and connected vehicles. Crucially, it\u2019s the 8-digit number that forms the first part of the 15-digit IMEI (International Mobile Equipment Identity), which uniquely identifies each individual connected device, so they can be transported around the world.<\/p>\n\n\n\n

TAC \/ IMEI also helps enable governments to collect the correct taxes, devices to operate globally on mobile networks, and the identification of counterfeit or stolen devices.

Who provides TAC?<\/h2>\n\n\n\n

Only the GSMA is authorised by 3GPP to allocate TAC for all GSM mobile device identities globally, through our appointed reporting bodies. We make sure it\u2019s allocated in compliance with standards, industry agreed practice and worldwide regulatory requirements.\u2028\u2028

GSMA TAC and IMEI Integrity Framework<\/h2>\n\n\n\n

The GSMA\u2019s priority is to maintain the integrity of the TAC identity system globally for the benefit of the entire ecosystem, promoting TAC \/ IMEI best practice through training and education.

With the rise in cloned and fake TAC \/ IMEI in some key markets, the GSMA initiated the TAC \/ IMEI Integrity Framework \u2013 encouraging all in the ecosystem to report mistakes and malpractice.

Activities include the Non-compliant TAC \/ IMEI Reporting Process and TAC Market Watch.<\/p>\n\n\n\n

FAQs<\/h2>\n\n\n\n
\n

How to get TAC <\/p>\n\n\n\n

\n

Manufacturers and brand owners \u2013 register your brand on the GSMA website. Then login credentials will be sent to the manufacturer to allow online application for TAC. Online TAC applications are usually issued within 48 hours, subject to payment.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

\n
\n

What devices need TAC?<\/p>\n\n\n\n

\n

Any device containing GSM cellular access functionality from the GSM family of standards, e.g., phones, smartphones, modems, dongles, tablets, PCs, IoT devices, payment terminals and vehicles. All must include an IMEI number generated from a GSMA-issued TAC code.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

\n

What are Type Allocation Codes?<\/p>\n\n\n\n

\n

A Type Allocation Code (TAC) is an 8-digit number for 3GPP devices that identifies the make and model \u2013 which is why different device models require different TAC. Manufacturers use TAC to create a unique number that identifies individual mobile devices, known as the International Mobile Equipment Identity (IMEI). The IMEI is embedded into the device at the time of manufacture so it cannot be modified.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

\n

Why do you need an IMEI?<\/p>\n\n\n\n

\n

The purpose of an IMEI number is to identify a specific mobile device, not just its make and model. Crucially, it enables the network operator to accurately identify the device before allowing it to access the network. Without knowing the model and its capabilities, including band profiles, proper interaction between the network and device can\u2019t be ensured. The device make and model are identified from the TAC component of the IMEI<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

\n

How to generate or create an IMEI<\/p>\n\n\n\n

\n

First, you need a TAC number, as you can\u2019t create an IMEI without one. So, register for a TAC Allocation account with the GSMA, then apply for a TAC code. If you are entirely new to the process, we strongly advise you to download and read our TAC Training Modules here<\/strong>.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

\n

Why is the GSMA allocating TAC?<\/p>\n\n\n\n

\n

The mobile industry appointed the GSMA as the Global Decimal Administrator (GDA) for 3GPP devices and multi-mode 3GPP\/3GPP2 compliant devices. The GSMA\u2019s role is to ensure TAC are allocated in compliance with standards, industry agreed practice and worldwide regulatory requirements.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n
