## Frequently asked questions

What is the area code for Rio de Janeiro?

The area code for Rio de Janeiro, Brazil is 21. Calling from outside Brazil, dial your exit code, then +55, then the area code without its trunk prefix, then the local number — written together as +55 21 followed by the subscriber number.

How do I call Rio de Janeiro from abroad?

From the United States or Canada, dial 011 + 55 + 21 + the local number. From most of Europe and from a mobile anywhere, replace the exit code with 00 or simply press and hold 0 to enter a plus sign, which works from any country without knowing its exit code.

Do I drop the 0 when calling Rio de Janeiro?

Yes. Brazil uses 0 as a trunk prefix for domestic calls, so Rio de Janeiro's code is written 21 locally and dialled as 21 from abroad. Keeping the trunk prefix in an international number is the single most common reason the call fails to connect.

How many digits is a Rio de Janeiro phone number?

A full Brazil number is 11 digits after the country code, area code included — for example +55 11 9 1234-5678. That length is fixed by the national numbering plan, so a number one digit short is a typo rather than a valid shorter number.

How much does it cost to call Rio de Janeiro?

Calling a Rio de Janeiro landline costs $0.14 a minute with Telvio and a mobile costs $0.14. Ten minutes to a landline is $1.40. Billing is per second with no connection fee, so a short call is charged for the seconds it used rather than rounded up to a whole minute.

## Call Rio de Janeiro with Telvio

From $0.14/min. Per-second billing, 1 free minute included.
