How to cancel ADT by mail
Collect the details you need
Put the account or subscription number, the email the plan was bought with and the address or devices it covers in front of you before you write: the request to ADT is only as good as the details it quotes.
Set out the request
State plainly that you want the ADT account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Subscription termination – ADT”).
Mail it with tracking
Send it certified to Boca Raton, United States, copying the address from the next section letter for letter, and keep the receipt slip.
Save the tracking record
Delivery confirmation is your evidence that ADT was asked. Watch the next statement or two for any further ADT charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

ADT can be reached by post at 1501 Yamato Rd, Boca Raton, FL 33431.
With ZIP 33431, the address sits in Florida and the letter never leaves the United States postal system.

Cancelling a security or identity-protection subscription
Security subscriptions often auto-renew and monitored plans can sit on a fixed contract term, so it matters when the request reaches the provider and whether it covers every device or location.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
ADT lets you cancel directly (online). A letter is the fallback that leaves a dated record when the direct route fails.
