If you do not wish to use our do-it-yourself guides, we suggest this cancellation service:


ADT is a Florida-based company that provides electronic security for small businesses and residential properties.

The public company launched in the 19th Century as American District Telegraph. In the past, it offered a telegraph-based, break-in alert system.

Today, the 144-year old corporation is a security system leader. Not only does ADT provide burglary monitoring, it also offers additional services. ADT now sells cybersecurity and health safety protection. Customers can also purchase smoke, fire, carbon monoxide detection monitoring.

ADT now offers video surveillance to residential homes.

The business provides three levels of service that require a 36-month commitment. Individuals have three days to cancel their contract. ADT does not offer any trial period past the initial three days.

In 2016, Apollo Global Management acquired ADT for $6.9 million through a leveraged buy out. In this guide, you’ll learn how to cancel your ADT account.

To get started on canceling your ADT account you will need:

  • Your full name associated with your ADT account.
  • The account password.
  • Your home address.
  • Your telephone number.
  • The type of account you hold with ADT.

Steps to Cancel

According to ADT, customers cannot cancel their services online. Individuals must contact the security company directly to request the termination of their services.

  1. Call 1-800-243-1748.
  2. Ask the customer service agent to cancel your ADT service.
  3. Request an email or letter confirming your ADT account cancellation.

Note: ADT’s security contracts are usually 36-months long. The company may require customers to pay a termination fee. If so, they’ll need to pay 75 percent of the remaining contract.

For example, if a person pays $50 per month, the individual will be required to pay $1,350 if they just started their ADT service and missed the three-day cancellation period.

Insider Tip: Continue to monitor your credit card statement to ensure that no additional fees are added. If you receive additional charges, please contact ADT’s customer service at 1-800-243-1743.
