Formatting phone numbers¶
Twilio always returns phone numbers that are formatted in the E.164 format, like this:
your users may enter them like this:
(212) 555-1234. This can lead to
problems when, for example, Twilio makes a POST request to your server with the
From phone number as
+12125551234, but you stored the phone number in
your database as
(212) 555-1234, causing a database lookup to fail.
We suggest that you convert the number to E.164 format before you store it in the database. The phony gem is excellent for this purpose. Install it like this:
$ gem install phony
Then you can convert user input to phone numbers like this:
require 'phony' def convert_to_e164(raw_phone) Phony.format( raw_phone, format: :international, spaces: '' ).gsub(/\s+/, "") # Phony won't remove all spaces end puts convert_to_e164('212 555 1234') # prints +12125551234
