A Ruby gem which plugs directly into Google's native C++ libphonenumber for extremely fast and robust phone number parsing, validation, and formatting. On average, most methods are 70x to 80x faster than other Ruby phone number libraries.


Checking if a phone number is valid

MiniPhone.valid?('+14043841399')                     # true
MiniPhone.valid_for_country?('(404) 384-1399', 'US') # true
MiniPhone.valid_for_country?('(404) 384-1399', 'GB') # false

Formatting a number

MiniPhone.default_country = 'US'

phone_number = MiniPhone.parse('404-384-1399')

phone_number.e164                 # +14043841399
phone_number.national             # (404) 384-1399
phone_number.raw_national         # 4043841399
phone_number.dasherized_national  # 404-384-1399        # +1 404-384-1399
phone_number.rfc3966              # tel:+1-404-384-1384

Checking if a phone number is possible

phone_number = MiniPhone.parse('-12')

phone_number.possible? # false

Getting the type of a phone number

MiniPhone.parse('+12423570000').type # :mobile
MiniPhone.parse('+12423651234').type # :fixed_line

The possible types are directly mapped from this enum:


Compatibility with PhoneLib

MiniPhone aims to be compatible with Phonelib. In many cases it can be a drop in replacement. It has a smaller feature set, so it is not a replacement for every use case. If there is a feature you need, open an issue and we will try to support it.


On average, most methods are 40x to 50x faster than other libraries. To run the benchmarks locally, execute: bundle exec rake bench
