How to Cancel ADT
Cancel ADT — requires calling 1-800-238-2727. Long-term contracts may include early termination fees up to 75% of remaining balance.
Cancellation friction
ADT requires calling customer service to cancel, involves a long-term contract (typically 36 months), and charges an early termination fee of up to 75% of remaining contract value.
Refund policy
No refunds. Early termination fee applies if cancelled before contract end (typically 75% of remaining balance).
Step-by-step instructions
- Step 1
Call ADT at 1-800-238-2727. There is no online cancellation option.
- Step 2
Say "Cancel" or navigate to account changes when prompted.
- Step 3
Ask the agent about your contract end date and any early termination fees before agreeing to cancel.
- Step 4
Get a cancellation confirmation number and ask for written confirmation by email.
💡 ADT contracts are typically 36 months. Cancelling early triggers an ETF of up to 75% of your remaining monthly payments.
Common issues
“How much will my ADT early termination fee be?”
Typically 75% of your remaining contract balance. For example, if you have 12 months left at $40/mo, that's $360 × 75% = $270. Ask for the exact amount before cancelling.
“I'm moving — can I transfer my ADT service?”
ADT allows service transfers to a new address. Call 1-800-238-2727 and ask about relocation options — this may avoid the ETF and is often cheaper than cancelling.
