Overview
CC routes to Brazil
CC routes to Brazil are tuned for dialer traffic: high call attempts, short average durations and bursts at shift start. We size capacity per campaign and watch short-call ratios, so your traffic stays welcome on the terminating networks.
Brazil is one of the few markets where a regulator watches call duration directly. CC routes report the share of sub-3-second calls per campaign in real time, so you can adjust before Anatel’s thresholds come into play.
Brazil is one of the largest contact-center markets in the world. Anatel has acted strongly against abusive telemarketing and high-volume short calls.

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

Brazil CC routes: 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.
Can I run predictive dialers to Brazil?
Yes, for lawful campaigns. Set conservative pacing, follow Brazil’s calling hours and opt-out rules, and keep your abandoned-call rate low. CC routes report short-call ratios per campaign so you can tune pacing with real data.
