IMEI Check Brazil: ANATEL Registration and Blacklist Verification

IMEI Check in Brazil: ANATEL's Homologation System Explained

Brazil has one of the strictest telecommunications equipment regulations in the world, enforced by ANATEL (Agência Nacional de Telecomunicações). Every phone sold or used in Brazil must be ANATEL-homologated — meaning officially approved and registered in the national IMEI database. Here's how to check your phone's ANATEL status and what it means.

What Is ANATEL Homologation?

ANATEL homologation is the process by which phones are officially approved for use on Brazilian telecommunications networks. A homologated device has been tested for electromagnetic compliance, SAR (radiation) limits, and network compatibility. Every approved model is assigned an ANATEL certification number.

Phones sold in Brazil by authorised retailers are homologated. Phones brought in from other countries (grey market imports) often are not — and Brazilian carriers can block them from their networks.

How to Check ANATEL Homologation via IMEI

  1. Find your IMEI by dialing *#06#
  2. Visit sistemas.anatel.gov.br/ahu/ (ANATEL's device verification portal)
  3. Enter your IMEI number to check if the device model is homologated
  4. Alternatively, check the physical device: homologated phones have an ANATEL certification mark/number on the back or in Settings

Finding the ANATEL Number on Your Phone

  • iPhone: Settings → General → Regulatory → the ANATEL number appears as a string starting with "ANATEL" followed by numbers
  • Android: Settings → About Phone → Regulatory → look for ANATEL certification
  • Physical device: Check the back of the phone or under the battery cover (older models) for a printed ANATEL certification mark

IMEI Blacklist in Brazil

Brazil's telecom operators maintain a joint IMEI blacklist through ANATEL. Phones are blacklisted for:

  • Reported theft or loss (boletim de ocorrência - police report required)
  • Non-payment of device financing (financiamento)
  • Cloned or counterfeit IMEIs

To check if a phone is blacklisted in Brazil, contact your carrier directly or use the carrier's app. For international blacklist status, imeicheckpro.com checks the GSMA global blacklist.

The "Bloqueio" — Brazil's Carrier Blacklisting for Theft

Brazil has extremely high smartphone theft rates in major cities (São Paulo, Rio de Janeiro). Brazilian carriers can blacklist ("bloquear") an IMEI almost immediately after a police report (boletim de ocorrência). The block applies to all national carriers simultaneously.

Buying Used Phones in Brazil: Checklist

  • ✓ Verify ANATEL homologation number is present and matches an approved model at sistemas.anatel.gov.br
  • ✓ Run IMEI check at imeicheckpro.com — verify brand and model
  • ✓ Ask the seller for the Nota Fiscal (Brazilian purchase receipt) — legitimate phones have one
  • ✓ Contact your carrier to confirm the IMEI is not blocked in their database
  • ✓ For iPhones: check iCloud lock status via premium IMEI report
