Frequently Asked Questions

▶How many digits does a Brazil phone number have?

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 accounts for all valid lengths when extracting numbers, so both mobile and landline formats are detected correctly.

▶Can NumSwift extract Brazil numbers written in local format?

Yes. NumSwift recognises Brazil numbers in local format ((11) 91234-5678), international format (+55 11 91234-5678), and various other common notations including with dots, dashes, or spaces as separators. The extraction engine is powered by Google's libphonenumber library, which supports all standard formats.

▶Does it work if the text mixes Brazil numbers with numbers from other countries?

NumSwift handles mixed-country text seamlessly. It identifies each number's country of origin based on the prefix and formatting patterns, so Brazil (+55) numbers are correctly distinguished from numbers belonging to other countries in the same text block.

▶Can I tell which Brazil carrier a number belongs to from the extracted results?

The leading digits of a Brazil mobile number often indicate the carrier — for example, Vivo and Claro each have recognisable prefix ranges. NumSwift extracts and displays the full number, allowing you to identify the likely carrier from the prefix based on Brazil's numbering allocations.
