Do it yourself

Cancel ADT yourself

TLDR: Call 800.327.4348 at least 30 days before the term ends, and the contract ends on the last day of that term. Cancel during the initial term and the posted contracts say you owe 75% of the remaining monthly charges right away.

Cancel monitoring by phone

Your plan is the ADT monitoring terms. That page says you may terminate by phone.

  1. 01Call 800.327.4348.
  2. 02Give the name and address on the account and say you want to terminate monitoring.
  3. 03Ask for the date the current term ends.

Those terms say the contract renews for 30-day terms unless either side ends it at least 30 days before the current term ends. It then ends on the last day of that term.

Cancel a self-install plan in the first 30 days

The equipment was for self-installation, and you are still inside 30 days of the contract date on the residential contract.

  1. 01Call 888-392-2039.
  2. 02Say you want to cancel under the 30-day self-install return policy.
  3. 03Ask for the Return Material Authorization number.
  4. 04Return the equipment to ADT's warehouse within 21 calendar days of that number, and keep proof of delivery.

This phone number is only in the self-install return policy. It is not the monitoring-terms number.

Cancel a SoSecure plan in the account

Your plan is the SoSecure services agreement. That agreement says you cancel in the account.

  1. 01Sign in to the ADT account for that plan.
  2. 02Use the cancel action the account shows.
  3. 03Save the screen that shows the end of the current term.

The agreement says ADT, or an approved provider such as in-app payments from Apple or Google, can charge the card on file. Cancelling in the account is the step that agreement describes.

Cancel a Nest Secure plan

Your contract is the Google Nest Secure terms.

  1. 01Call 800.238.2727.
  2. 02Or open the order confirmation email, click the cancellation button, and finish the form.

That contract says you can do this before the 12-month point, and anytime after billing has started.

How to know it worked

  • On the monitoring terms, the contract ends on the last day of the current term if you give notice at least 30 days before that term ends.
  • On the SoSecure agreement, a paid plan ends at the end of the current term. There is no refund of money already paid for that term.
  • Ask the agent, or the account screen, for the end date. The pages do not promise a separate confirmation email.

Watch out for

  • The posted residential contract says its early-termination clause is based on an initial term of 1 month. The monitoring terms say the initial term is the term you selected at checkout. The term on your signed contract is the one that applies.
  • If you cancel during that initial term, both of those contracts say you pay 75% of the remaining monthly charges, due immediately. That charge is not waived by cancelling. It is not due if you cancel during a 30-day renewal period.
  • If you miss the required termination notice, the contract lets ADT deduct 30 days of service charges from any refund.
  • If ADT raises the annual charge after the first year, you can object in writing within 30 days of the notice. If ADT does not drop the increase, you may end the contract 30 days after ADT receives that objection, without the termination charge in that paragraph. Those pages do not print a street for that letter.
  • Self-install equipment is separate from stopping the next renewal. Miss the 21 days after the return number and the contract says you do not get the equipment-cost refund. Shipping you already paid is not refunded. After the first 30 days, termination charges apply.
  • The Nest Secure contract charges $19.99 a month, plus tax, on the date 12 months after the equipment is activated, unless monitoring was cancelled before then. Its initial term is 1 month, then 30-day renewals.
  • A SoSecure cancel does not refund the prepaid term. An unreturned-equipment fee on a monitoring plan can be taken from a deposit.

ADT refunds

  • Cancelling does not erase a contract termination charge. During the initial term, the posted contracts say you owe 75% of the remaining monthly charges.
  • The self-install return policy says the equipment cost is refunded if you cancel within 30 days of the contract date and return the equipment within 21 calendar days of the return number. The monthly service fee is refunded only if service was never activated. Shipping already paid is not refunded.
  • The SoSecure agreement says you are not entitled to a refund of money prepaid for a paid service term.
  • A security deposit, if ADT holds one, comes back within 45 days of termination, or the time the law sets, minus termination charges, unreturned-equipment fees, false-alarm fines, and unpaid service or installation charges. No interest.

If it did not work

No confirmation email? Then it didn't happen.

Our letter comes with a receipt. This is when it is worth having us do it.

Have us cancel ADT
  • You cannot log in, or do not remember the email

    The notice goes to ADT Security Services in your name and address. No login, no password.

  • You are still inside the initial term

    The notice dates the request. The contract can still charge 75% of the remaining monthly charges. Cancelling does not make that charge disappear.

  • You were charged after cancelling

    The dated notice and proof of delivery are what your bank asks for when you dispute the charge.

  • The equipment is still out

    Stopping monitoring and returning equipment are separate. The notice ends the service request. The return clock, and any unreturned-equipment fee, stay on their own.

  • You would rather not chase support

    We post and email the notice, then follow up with ADT until they confirm. If they never do, you get your money back.

Cancelling ADT

What people ask about ADT.

How do I cancel ADT monitoring?

On the monitoring terms, call 800.327.4348 at least 30 days before the current term ends. The contract then ends on the last day of that term. A SoSecure plan is cancelled in the account. A Nest Secure plan uses 800.238.2727 or the cancellation button in the order confirmation email.

Will I still owe money after I cancel?

You can. During the initial term, the posted contracts say you pay 75% of the remaining monthly charges, due immediately. That is not due during a 30-day renewal period. Your signed contract shows the initial term. The posted residential page says 1 month. The monitoring terms say the term you picked at checkout.

Does cancelling make me return the equipment?

Those are separate. On a self-install plan cancelled within 30 days of the contract date, call 888-392-2039 and return the equipment within 21 calendar days of the return number or you do not get the equipment-cost refund. On other plans, an unreturned-equipment fee can be taken from a deposit.

I have a SoSecure plan paid through Apple or Google. Where do I cancel?

The SoSecure agreement says you cancel in the ADT account, and that ADT or an approved provider such as Apple or Google in-app payments can charge the card. There is no refund of the prepaid term. The agreement ends at the end of that term.

Can you cancel ADT without me logging in?

Yes. The notice goes to ADT in writing, so it does not depend on you reaching a cancel button inside your account. A lost password or a locked account does not stop it.

Does the letter ask them to delete my data?

Yes. It asks the company to erase the personal data it holds on you where it has no lawful reason to keep it, and to confirm in writing once it has.
