Brazil Implements Mandatory TAC Codes for Mobile Devices

September 25, 2019


On July 10, 2019 the Brazilian ANATEL issued an Official Letter 25/2019/ORCN/SOR-ANATEL, which requires all Mobile Device suppliers and manufacturers applying for certification of regulated products to register the TAC (Type Allocation Code - composed by the first 8 digits of IMEI). The document is applicable to all devices with WWAN functions that will use the SMP (Portable Mobile Service), such as Mobile Phones, Tablets, Modules and all other terminal using WWAN.


Registration of the TAC codes of the products must be done in the system database developed by ABR Telecom, called SIGA (Integrated Device Management System), prior to their sale.


SIGA (Sistema Integrado de Gestão de Aparelhos) is a centralized technological solution integrated with the SMP Providers (Carriers). Its purpose is to treat and combat the use of cloned, adulterated or uncertified IMEIs in the Mobile Operator networks.

The TAC registration system is available via link. 


The registration can be done only by the Brazilian Manufacturer or the Local Representative company in Brazil. 


The flowchart below should be provided by the OCD to the applicant at the beginning of product certification:

Thus, the manufacturer or supplier will have to declare their knowledge of the obligation to register the TAC (s) in the GSMA.


Anatel also asked the OCDs to emphasize the applicant (manufacturer/importer for the certification process) the importance and necessity of registering each TAC code with the GSMA under penalty of having access of the mobile terminal blocked in the network of the providers of the country's mobile services, even if it is homologated by Anatel, due to the absence or non-compliance of the information in the SIGA system database.


Therefore, it is the responsibility of the applicant for the homologation of the damages caused to the users for not complying with this determination, agreed at the plenary meeting of the Working Group of the Legal Cell Project.


In this document, Anatel also requests that the company concerned contact ABR Telecom via for the purposes of registering the TAC numbers and for clarifying other information on the procedure.
