Your partANATEL certification is how any telecommunications product gets permission to be sold in Brazil. ANATEL certification is the route by which any telecommunications product, including a household appliance with Wi-Fi, Bluetooth or a cellular modem inside it, gets permission to be sold in Brazil. Under Resolução nº 715/2019 an Organismo de Certificação Designado (OCD) evaluates test reports from an ANATEL-recognised laboratory and issues a certificate of conformity; ANATEL then homologates the product and assigns a number that must be marked on it under Ato nº 4088/2020. The applicant must be a Brazilian legal entity with a CNPJ, and routers, modems and similar customer equipment must also meet the cybersecurity requirements of Ato nº 77/2021.
Wi-Fi, Bluetooth, Zigbee, LoRa, cellular, NFC or active RFID puts a product in scope under Resolução nº 715/2019, whatever its main function. A washing machine with a Wi-Fi module counts.
Run the scope check at the design stage; homologation has no expedited track.
An Organismo de Certificação Designado evaluates reports from an ANATEL-recognised laboratory and issues the certificate. ANATEL then homologates the product and assigns a number, marked on it under Ato nº 4088/2020.
Decide the label or settings screen for the number along with the tooling.
The applicant is a Brazilian legal entity with a CNPJ: your local subsidiary, the importer, or a representative appointed for the purpose. ANATEL records the homologation against that entity in Mosaico.
A change of importer later means transferring or reissuing the homologation.
An ANATEL file goes wrong at the start when the product is scoped as the wrong type and the reports cover the wrong tests. A module-based design that changed the antenna, the placement or the output power has to run its radio tests again on your product. Routers and modems add their own stop: they arrive at homologation without the cybersecurity work Ato nº 77/2021 requires.
The homologation sits in Mosaico against the CNPJ holder named on it, and the number belongs to that entity. An old importer's number cannot simply be printed on a new importer's goods. Where the product type carries periodic product evaluation, a maintenance lapse of more than 180 days ends in suspension and then cancellation. The module's radio evaluation stays reusable only while your design matches the conditions the module maker declared.
What we handle
Everything here is something to find before the project starts. The first reply says which of it can go into the file as it is.
One specialist owns your file from the first email to the registered certificate. Every one of them has recorded a briefing on their field.
Each stage is a service of its own, with a page that says what it produces and what it needs from you.
The cheapest stage decides the cost of every stage after it. What a route assessment names, and the four decisions it locks down.
Read the pageAccreditation is per standard and per laboratory, never general. How to choose one the destination accepts, and test once for several markets.
Read the pageThe file is the certificate’s foundation and it is the manufacturer’s to produce. What it has to contain, and what cannot be written retrospectively.
Read the pageAudits turn a schedule from weeks into months and cannot be compressed. What auditors check, and how to be ready for the first visit.
Read the pageFour major markets refuse to certify a foreign manufacturer directly. What the appointment obliges, and why a distributor is the wrong holder.
Read the pageA correct certificate and a wrong label still stops at the border. What each market demands on the artwork, and when to check it.
Read the pageEvery product that ANATEL classes as a telecommunications product: phones and modems, network equipment, satellite terminals, and any device with a radio transmitter, whether Wi-Fi, Bluetooth, Zigbee, LoRa, cellular, NFC or active RFID. Cables, connectors, antennas and power supplies for telecommunications use are on the list as well.
The transmitter is what puts a product in scope, whatever its main function. Appliance makers, vehicle-tracker suppliers, smart-lock and metering companies meet the requirement late because they do not see themselves as telecommunications companies. A washing machine with a Wi-Fi module is a telecommunications product for homologation purposes.
Homologation has no expedited track. A product discovered to need it while the goods are already at sea waits for testing, the OCD and ANATEL like every other product, and the cargo waits with it. The scope check at the design stage takes an afternoon.
It shortens the work. Building around a module that already holds its own ANATEL homologation lets the OCD reuse the module's radio evaluation, so the finished product is tested for what the module does not cover: electrical safety, electromagnetic compatibility, and SAR where the device is used near the body. The finished product still receives its own certificate and its own homologation number.
The reuse holds only while the product matches the conditions the module maker declared. Those conditions cover the antenna type and gain, where the module is placed in the enclosure, and the output power it is configured to. Change any of them and the radio tests are yours to run again, and the saving that justified the module is gone.
Since Ato nº 77/2021, issued under Resolução nº 740/2020, customer premises equipment such as routers, modems and optical network terminals must also satisfy cybersecurity requirements at homologation, covering credentials, software updates and the handling of vulnerabilities. A module homologation covers none of that.
The applicant is a legal entity with a Brazilian CNPJ: the manufacturer's local subsidiary, the importer, or a representative appointed for the purpose. ANATEL records the homologation in its Mosaico system against that entity, so a change of importer is a regulatory event and the new importer generally needs the homologation reissued in its own name or transferred.
Resolução nº 715/2019 replaced the old categories I, II and III with product types and families, and it sets two shapes of certification. Type-testing certification issues a certificate once, with no maintenance phase. Type testing with periodic product evaluation adds a maintenance cycle in which samples are taken from production or the market and retested; the cycle is fixed per product type in ANATEL's reference list, and a certificate whose maintenance lapses for more than 180 days is suspended and then cancelled.
After homologation the number must appear on the product, either physically or on screen, under the marking procedure in Ato nº 4088/2020. Inspectors check the marking on the shelf; the certificate in a drawer does not satisfy them. Decide the label or the settings screen with the tooling, before the first production run.
| Step | Who does it | Note |
|---|---|---|
| Scope and product type | OCD, with the manufacturer | Sets the tests and whether periodic evaluation applies |
| Testing | Laboratory recognised by ANATEL | RF, electrical safety, EMC, SAR where applicable; cybersecurity for CPE under Ato 77/2021 |
| Certificate of conformity | OCD (Organismo de Certificação Designado) | Issued under Resolução 715/2019; the basis for homologation |
| Homologation | ANATEL, in the Mosaico system | Assigns the number to the CNPJ holder |
| Marking | Manufacturer | Number visible on product, packaging or screen per Ato 4088/2020 |
| Maintenance | OCD, per product type | Periodic sample evaluation where the reference list requires it |
Yes. Anything with a transmitter, whether Wi-Fi, Bluetooth, cellular, LoRa or active RFID, is a telecommunications product for homologation under Resolução nº 715/2019, whatever its main function. Connected appliances, trackers and smart meters are included, and homologation must be complete before the product is offered for sale in Brazil.
It reduces the testing without removing the obligation. The finished product still gets its own certificate and homologation number. The OCD reuses the module's radio evaluation only if you keep to the antenna, placement and output power the module maker declared; change any of them and the radio tests are repeated on your product.
A legal entity with a Brazilian CNPJ: a local subsidiary, the importer, or an appointed representative. ANATEL records the homologation against that entity in Mosaico, so a change of importer later means transferring or reissuing the homologation, and the old importer's number cannot simply be printed on the new importer's goods.
Six to fourteen weeks in most cases, covering the laboratory tests, the OCD's certificate and the homologation itself. The laboratory queue sets the pace. A product scoped as the wrong type at the start, so that the reports cover the wrong tests, is what pushes a project past the range.
