Phone Numbers

With Twilio you can search and buy real phone numbers, just using the API.

For more information, see the IncomingPhoneNumbers REST Resource documentation.

Searching and Buying a Number

Finding numbers to buy couldn’t be easier. We first search for a US number in area code 530. Once we find one, we’ll purchase it for our account.

require 'twilio-ruby'

# To find these visit

@client = account_sid, auth_token
numbers = @client.available_phone_numbers.get('US').list(area_code: "530")

if numbers.any?
  puts "No numbers in 530 available"

Local, Toll-Free, and Mobile Numbers

By default, looks for local phone numbers. You can search for different types of numbers by using a type subresource.

Available subresources for AvailablePhoneNumbers are: - local - toll_free - mobile

You can search for numbers for a given type.

# local
numbers = @client.available_phone_numbers.get('US').local.list()

# toll free
numbers = @client.available_phone_numbers.get('US').toll_free.list()

# mobile
numbers = @client.available_phone_numbers.get('UK').mobile.list()

Numbers Containing Words

Phone number search also supports looking for words inside phone numbers. The following example will find any phone number with “FOO” in it.

numbers = @client.available_phone_numbers.get('US').list(contains: "FOO")

You can use the ‘’*’’ wildcard to match any character. The following example finds any phone number that matches the pattern ‘’D*D’‘.

numbers = @client.available_phone_numbers.get('US').list(contains: "D*D")

Other Number Searches method has plenty of other options to augment your search :

  • region: When searching the US, show numbers in this state
  • postal_code: Only show numbers in this area code
  • rate_center: US only.
  • near_lat_long: Find numbers near this latitude and longitude.
  • distance: Search radius for a Near- query in miles.
  • beta: Include or exclude numbers that are new to the Twilio platform.

The AvailablePhoneNumbers REST Resource documentation has more information on the various search options.

Numbers Requiring Addresses

Some phone numbers require you to have an address on file with Twilio to satisfy legal requirements before they can be purchased. By default, the client library will include numbers in the result lists regardless of their address requirements; you can filter these numbers out when searching for phone numbers to purchase.

# Exclude all numbers requiring addresses
numbers = @client.available_phone_numbers.get('AU').list(exclude_all_address_required: true)

# Exclude numbers requiring local addresses
numbers = @client.available_phone_numbers.get('AU').list(exclude_local_address_required: true)

# Exclude numbers requiring foreign addresses
numbers = @client.available_phone_numbers.get('AU').list(exclude_foreign_address_required: true)

Buying a Number

If you’ve found a phone number you want, you can purchase the number.

require 'twilio-ruby'

# To find these visit

@client = account_sid, auth_token
@number = @client.available_phone_numbers.purchase(
  phone_number: "+15305431234"

However, it’s easier to purchase numbers after finding them using search (as shown in the first example).

Updating Properties on a Number

To update the properties on a phone number, call update() on the phone number object, with any of the parameters listed in the IncomingPhoneNumbers Resource documentation

require 'twilio-ruby'

# To find these visit

@client = account_sid, auth_token
@client.available_phone_numbers.list.each do |number|
    voice_url: "" \
    status_callback: ""

Changing Applications

An Application encapsulates all necessary URLs for use with phone numbers. Update an application on a phone number using update().

require 'twilio-ruby'

# To find these visit

@client = account_sid, auth_token


@number = @client.available_phone_numbers.get(phone_sid)
@number.update(sms_application_sid: "APXXXXXXXXXXXXXXXXXX")

See Applications for instructions on updating and maintaining Applications.
