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.
