Will I be charged an early termination fee if I cancel ADT Command?

Yes, if you are within your contract period (typically 36 months, or 24 months in California), ADT charges up to 75% of the remaining monthly fees as an early termination fee. Review your contract or check myadt.com to calculate your specific amount before calling.

Can I cancel ADT Command online without calling?

Online cancellation via myadt.com is only available if your ADT system was originally purchased online. You will see a 'Cancel Subscription' form in your account if eligible. Otherwise, cancellation must be done by phone at 1-800-238-2727.

How much notice does ADT require to cancel?

ADT requires 30 days' notice to cancel. You can give notice over the phone, or send a written notice to: ADT Security Services, PO Box 650823, Dallas, TX 75265, including your name, address, account number, and requested cancellation date.

Can I reactivate my ADT Command service after cancelling?

Yes, ADT allows reactivation. Contact 1-800-238-2727 to restart monitoring. You may need to sign a new monitoring contract and potentially pay for a technician visit if equipment needs reconnecting.

What happens to my ADT Command system hardware after I cancel?

If you purchased the equipment outright, you keep it and it remains functional as a local alarm (without professional monitoring). If equipment was provided under a lease or financing agreement, ADT may require its return. Confirm ownership terms with the agent during cancellation.

Is there a way to cancel ADT without paying the early termination fee?

Yes, in limited cases: (1) Cancel within 72 hours of signing (buyer's remorse window) for no penalty. (2) Invoke the 6-month satisfaction guarantee if ADT has failed to resolve service issues within your first 6 months. (3) If you are moving to an area ADT does not serve, they may waive the ETF. Document all attempts to resolve issues before requesting a waiver.

Locate your account details

Log in to myadt.com to find your account number, contract end date, and remaining months. You'll need this info ready before calling. Note your current monthly rate to calculate any early termination fee (up to 75% of remaining contract balance).

Check for online cancellation eligibility

On myadt.com, look for a 'Cancel Subscription' option under your account settings. This option only appears if your ADT system was originally purchased online. If you do not see it, you must cancel by phone.

Call ADT cancellation line

Call 1-800-ADT-ASAP (1-800-238-2727). When the automated system answers, say 'Cancel service' or press the option for 'Account changes' or 'Cancel monitoring' to be routed to the retention/cancellation department.

Verify your identity

The agent will ask for your account number, the verbal security password or passcode on your account, and the service address. Have these ready to avoid delays.

State your intent to cancel and decline retention offers

Clearly state 'I want to cancel my ADT monitoring service.' The agent will likely offer discounts, a rate reduction, a service upgrade, or a pause option. Decline firmly if you wish to proceed. Ask the agent to confirm your early termination fee (ETF) amount if you are still under the 36-month contract.

Set cancellation date and confirm 30-day notice

ADT requires 30 days written or verbal notice. Confirm the exact cancellation effective date with the agent. Request a cancellation confirmation number and ask for an email confirmation of the cancellation.

Arrange equipment and final billing

If any equipment was rented (not purchased), ask the agent about return procedures. Confirm your final bill amount, including any ETF charges. ADT will send a final invoice; verify no further charges appear after the cancellation date.
