Unknown calls from Brazil
Brazilians receive a steady stream of unknown calls, and many go unanswered on principle. Telemarketing for phone plans, credit and insurance is heavy enough that regulators created a dedicated 0303 prefix and blocked robocallers making abusive volumes of calls. The bigger worry is fraud: fake bank call centres, criminals posing as relatives with a "new number" on WhatsApp, and schemes built around the instant Pix payment system. With so much at stake from a single answered call, checking an unfamiliar number before replying has become common practice.

- Numbers include a two-digit area code (DDD). Mobiles have nine digits beginning with 9, e.g. (11) 91234-5678; landlines have eight digits. Domestic long-distance calls add 0 and a two-digit carrier code before the DDD.

To call a Brazilian number from abroad, drop the leading 0 and dial +55 first: (11) 91234-5678 becomes +55 11 91234-5678. A missed call showing +55 at the start came from a Brazil number.
How to tell what kind of Brazilian number called you
Mobile numbers
| Type | Starts with | Notes |
|---|---|---|
| Mobile | DDD + 9 | All mobiles have nine digits starting with 9 after the two-digit area code, e.g. 11 9XXXX-XXXX in São Paulo or 21 9XXXX-XXXX in Rio de Janeiro. Portability means the number does not show the carrier. |
Toll-free, premium and special numbers
| Type | Starts with | Notes |
|---|---|---|
| Toll-free | 0800 | Free-to-call customer service numbers. |
| Telemarketing | 0303 | Mandatory prefix for active telemarketing calls, so consumers can identify sales calls. |
| Shared-cost | 0300 | Nationwide numbers charged to the caller. |
| Capital numbers | 4004 / 4003 | Eight-digit business numbers dialled without an area code; used by banks and large companies. |
Mobile networks in Brazil
Numbers can be ported between networks, so the prefix alone does not prove which carrier a number is on today. A WhoCallsMe lookup reads the current carrier of record. The main mobile operators are:
- Vivo
- Claro
- TIM
