Twilio Error 21614
Understanding Twilio's SMS Communication API
Twilio is a cloud communications platform that enables developers to build, scale, and operate real-time communications within their software applications. It provides APIs for SMS, voice, video, and other communication channels, allowing seamless integration into applications. The SMS Communication API is particularly popular for sending and receiving text messages globally.
Identifying the Symptom: Error 21614
When using Twilio's SMS API, you might encounter the error code 21614. This error indicates that there is an issue with the format of the 'To' phone number in your API request. The error message typically reads: "The 'To' phone number is not a valid phone number."
Understanding the Issue: Invalid Phone Number Format
Error 21614 occurs when the phone number provided in the 'To' field of your API request is not in the correct format. Twilio requires phone numbers to be in the E.164 format, which includes the country code and omits any unnecessary characters like dashes or spaces.
What is E.164 Format?
The E.164 format is an international standard for phone numbers. It ensures that phone numbers are globally unique and recognizable. A valid E.164 number includes:
- A '+' sign
- Country code
- Subscriber number
For example, a US phone number would be formatted as +14155552671.
Steps to Fix Error 21614
To resolve Error 21614, follow these steps to ensure your phone number is correctly formatted:
Step 1: Verify the Phone Number
Ensure that the phone number you are using is correct and active. Double-check for any typographical errors.
Step 2: Format the Number in E.164
Convert your phone number to the E.164 format. Remove any spaces, dashes, or parentheses. Ensure it starts with a '+' followed by the country code and the subscriber number.
Example: +14155552671
Step 3: Update Your API Request
Modify your API request to include the correctly formatted phone number. Here is a sample API request using Twilio's API:
curl -X POST https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/Messages.json \
--data-urlencode "To=+14155552671" \
--data-urlencode "From=+15017122661" \
--data-urlencode "Body=Hello, this is a test message!" \
