Cancel a Number

If you no longer require a Vonage virtual number that you have purchased you can cancel it.

This page shows you how to cancel a number programmatically.

You can also cancel a number online, using the developer dashboard or from the command line, using the Nexmo CLI.

Replace the following variables in the sample code with your own values:

Key Description
VONAGE_API_KEY Your Vonage API key (see it on your dashboard).
VONAGE_API_SECRET Your Vonage API secret (also available on your dashboard).
COUNTRY_CODE The two digit country code for the number. For example: GB for the United Kingdom
VONAGE_NUMBER Your Vonage Number. E.g. 447700900000

  • Ruby

    • Write the code

    Add the following to cancel-number.sh:

    curl -X POST \
  "https://rest.nexmo.com/number/cancel?api_key=$VONAGE_API_KEY&api_secret=$VONAGE_API_SECRET" \
  -H "Content-Type: application/x-www-form-urlencoded" \
