1

Port your numbers first

Before canceling, contact your new phone provider and initiate a port of any numbers you want to keep. Phone numbers cannot be transferred after the account is closed. Once you've started the port, note the expected completion date.

2

Log in to Admin Portal

Sign in to https://admin.vonage.com/ using your Super User or Account Administrator credentials. Only Super Users and Account Administrators can cancel — standard users cannot initiate cancellation.

3

Navigate to Account Details

From the Admin Portal dashboard, click on 'Account Details' in the left navigation menu. This section contains the self-service cancellation option (available only if your account was originally created through Vonage's self-service signup flow, not via a sales rep).

4

Submit cancellation request

Follow the in-portal prompts to submit your cancellation request. Select a future cancellation date that aligns with your billing cycle and gives enough time for any number ports to complete. If prompted, push the date out further if your port is still in progress.

5

Call to cancel (if not self-service)

If the online option is not available (contract/sales-rep accounts), call Vonage Business Support at 1-866-901-0242 (Mon–Fri 8 AM–12 AM EDT, Sat–Sun 9 AM–9 PM EDT). State clearly that you want to cancel. Have your account number, admin email, billing address, and PIN ready. You will be routed to the Retention Department.

6

Decline retention offers and confirm cancellation

The retention agent will likely offer discounts or service downgrades to prevent cancellation. Decline these offers firmly and ask for a cancellation confirmation ticket number, the agent's name, the effective cancellation date, and written email confirmation.

7

Follow up to verify cancellation

Call back 1–2 business days later to confirm the cancellation was actually processed — post-cancellation billing without the account being closed is a documented pattern. Ask the agent to confirm your account status is 'closed' or 'pending closure' and note the ticket number.
