Overview

DID numbers to Brazil

A DID (direct inward dialing) number gives you a real Brazil number on your SIP trunk. It receives calls from local customers and, because you hold it, it is also the strongest caller ID you can present on outbound traffic to Brazil.

Brazilian geographic numbers in São Paulo, Rio de Janeiro and other main cities are available with local documentation, for inbound support lines and outbound CLIs.

Brazil is one of the largest contact-center markets in the world. Anatel has acted strongly against abusive telemarketing and high-volume short calls.

Caller ID rules in Brazil

A practical summary for operations teams, not legal advice. Confirm current requirements with counsel before you launch.

Last reviewed

Caller-ID presentation

Since March 2022, Anatel has required active telemarketing calls to use the 0303 prefix so recipients can recognise them. Anatel also blocks companies that place very high volumes of very short calls, a measure aimed at robocalls.

Call authentication

Anatel is rolling out “Origem Verificada”, a caller-authentication scheme based on the same principles as STIR/SHAKEN, starting with large businesses. Confirm its current scope before relying on it.

0303 prefix

Anatel requires the 0303 prefix for active telemarketing calls, so consumers can identify and block them.

Não Me Perturbe

The industry-run “Do Not Disturb” list lets consumers opt out of telemarketing from telecoms and banks.

Robocall and short-call measures

Anatel monitors and sanctions high volumes of very short calls. Keep dialer pacing and abandon rates under control.

Calling hours

Industry self-regulation limits telemarketing hours; follow the latest Anatel and consumer-protection guidance.

Dialing & setup

Dialing Brazil correctly

  • Brazil has no trunk 0 in E.164: +55, two-digit area code (DDD), then the number.
  • All mobiles have nine digits starting with 9. Old 8-digit mobile numbers in lead lists fail.
  • Do not send carrier-selection codes (the two digits after 0 in national long-distance dialing) on international routes.
  • Scrub against “Não Me Perturbe”, the industry opt-out list for telecom and bank offers.

Caller ID best practice

Telemarketing calls must use the 0303 prefix so consumers can identify them. Service calls should present a recognisable Brazilian number.

Troubleshooting

Common SIP errors on Brazil calls

  • 404

    Not Found

    A mobile number is missing its leading 9, or the area code is wrong.

  • 403

    Forbidden

    Telemarketing traffic without a 0303 CLI, or traffic from a sender blocked under Anatel’s short-call measure.

  • 480

    Temporarily Unavailable

    Handset off or out of coverage.

FAQ

Brazil DID numbers: FAQ

Can’t find what you need? Our routing team answers within the hour, around the clock.

Do I need the 0303 prefix for Brazil?

For active telemarketing to Brazilian consumers, yes. Customer-service and collections calls generally present a standard Brazilian number.

Why does Anatel care about short calls?

High volumes of very short calls are a hallmark of robocalling. Anatel can sanction originators. Our quality monitoring flags short-call patterns early so you can adjust dialer pacing.

What is the 0303 prefix?

A numbering range Anatel reserved for active telemarketing. Sales calls must present a 0303 number so recipients can identify them. Collections and service calls use ordinary numbers.

What is Anatel’s short-call rule?

Anatel can block companies that place huge daily volumes of calls lasting under three seconds, which is the signature of robocalls and aggressive predictive dialing. Tune your dialer to avoid instant hang-ups.

Do Brazilian mobile numbers need the ninth digit?

Yes. Every Brazilian mobile number has nine digits starting with 9. Lists from before 2016 may still contain 8-digit mobiles, which must be updated.

What documents do I need for Brazil DIDs?

It depends on the number type. Many geographic numbers in Brazil require proof of a local address or business registration; toll-free and non-geographic numbers usually need less. The portal lists requirements per number type before you order.
