Brazil Phone Number Format & Country Code +55
Brazilian mobile numbers are 11 digits including the 2-digit area code (DDD) and a mandatory 9 prefix for mobiles. Landlines are 10 digits with the same DDD area code. To dial a Brazil number internationally, replace the local trunk prefix with +55. For example, (11) 91234-5678 becomes +55 11 91234-5678. NumSwift converts between these formats automatically, validating each number against Brazil's numbering plan.

Frequently Asked Questions
▶What is the country code for Brazil?
Brazil's country code is +55. When dialing a Brazil number from abroad, you replace the local trunk prefix with +55. For example, the local number (11) 91234-5678 becomes +55 11 91234-5678 in international format.
▶How many digits are in a Brazil phone number?
Brazil phone numbers are 11 digits after the country code. Brazilian mobile numbers are 11 digits including the 2-digit area code (DDD) and a mandatory 9 prefix for mobiles. Landlines are 10 digits with the same DDD area code. NumSwift validates the digit count automatically, so incorrectly truncated or padded numbers are flagged as invalid.
▶What is the difference between mobile and landline formats in Brazil?
