ADT Customer Service Numbers, Billing, Cancellation, Alarm Support and Reviews

ADT customer service can be reached at 1-800-238-2727 (1-800-ADT-ASAP) for billing, monitoring cancellation, account questions, technical support, service appointments and most existing-customer problems. If an alarm involves an actual fire, break-in, medical emergency, carbon monoxide concern or immediate danger, call 911 first rather than waiting for ordinary customer service.

Last verified: August 29, 2026. Phone numbers, support routes, contracts, fees and equipment policies can change. Confirm account-specific terms directly with ADT.

ADT Customer Service Phone Numbers and Support Options

ADT does not publish one universal direct number for every panel, app and account type. Use the main number or the official Contact ADT Support page when the system does not match a specialized route above. Avoid unofficial “direct support” numbers unless the same number appears in the signed agreement, MyADT account or current ADT help article.

Best ADT Contact Route by Problem

Information to Have Ready

• ADT account or customer number
• Name on the account, service address and billing ZIP code
• Verbal security password if ADT requires it for secure verification
• System family, such as ADT+, Command, ADT Control, Pulse, Self Setup, Blue or an older panel
• Exact trouble message, zone number, device model or app error
• Signed agreement, promotional offer and equipment-financing documents
• Bill, payment confirmation, service invoice or promised credit
• Technician appointment date, work-order number and service notes
• Move date and both addresses when transferring service
• Permit number, false-alarm notice or municipal fee document
• Prior case number, call date, chat transcript and requested resolution

Do not post an alarm passcode, verbal security password, full account number, address, phone number, payment details, camera footage, monitoring instructions or information that reveals a security weakness in a public review.

ADT Billing, Payments and Unexpected Charges

Use MyADT to review bills, make a payment, manage EasyPay and download account documents. ADT’s current billing help directs customers to 1-800-238-2727 for telephone assistance. The phone menu can change, so listen for the current billing and payment option.

An ADT bill can contain more than monthly monitoring. Depending on the agreement and account, charges may involve equipment, installation, activation, taxes, permits, guard response, service visits, an extended service plan, late payments, financing or contract termination. Before disputing a charge, compare:

• The signed monitoring and equipment agreements
• The original written quote and promotion
• The installation invoice and any change orders
• The latest bill and prior months
• Equipment-financing statements, if a separate lender or payment plan is involved
• Technician service notes and any quoted visit fee
• Credits, refunds or rate adjustments ADT promised

Ask the representative to identify each disputed amount and provide a case number. If a credit is approved, ask when it should appear and whether it will reduce the next bill or be refunded to the original payment method. Do not cancel a card or block all payments before understanding how that action could affect a valid monitoring agreement or equipment balance.

How to Cancel ADT Monitoring and Check Contract Terms

ADT directs monitoring-cancellation requests to 1-800-238-2727. Have the actual agreement ready. Cancellation rules can differ by account, state, authorized dealer, system, monitoring plan, initial term, renewal status and equipment arrangement.

1. Ask the representative to identify the contract’s initial end date and current renewal status.
2. Ask whether advance written notice is required and where it must be sent.
3. Request the exact cancellation effective date and the last day of monitoring.
4. Ask for an itemized estimate of the final bill, including any contract termination charge.
5. Confirm whether equipment is owned, financed, leased or must be returned.
6. Ask whether canceling monitoring affects a separate equipment-financing agreement.
7. Request a cancellation case number and written confirmation.
8. After the final payment posts, check MyADT and the payment account for another billing cycle.

ADT’s current residential monitoring contract also addresses notice, renewals, price increases, permits and termination charges. The customer’s signed agreement controls the account, so online examples should not be treated as a substitute for that document or legal advice.

Self Setup Equipment Returns

For ADT Self Setup or former Blue by ADT return questions, call 1-877-464-7437. Ask for the return window, return authorization, shipping label, complete device list and any non-returned equipment fee. Photograph the equipment and package, keep the carrier tracking number and retain the delivery confirmation until ADT confirms the return.

Moving, Transferring or Leaving an ADT-Equipped Home

ADT recommends calling at least 30 days before a move. Current ADT moving guidance lists 1-866-321-4238. The options depend heavily on the system and installation type.

• Professionally installed system: ADT says professionally installed equipment generally is not moved to the new home. Ask what stays with the property and what service will be installed at the new address.
• Self-setup system: Some equipment may be packed and reinstalled at the new address. Confirm the device list and monitoring procedure before disconnecting it.
• Current home: Confirm the monitoring end date, who will have access after the move and whether the buyer can start separate service.
• New home: Ask about installation charges, equipment, internet requirements, permits, monitoring price and whether a new term begins.

Do not assume “transfer” means the original agreement continues unchanged. Obtain the new-address quote and service terms in writing, and compare them with the existing contract before agreeing.

Alarm Events, False Alarms, Emergency Contacts and Permits

Actual Emergency

ADT’s equipment guidance says to call 911 first in an emergency. If you cannot call, use the panic, fire or medical function available on the system as instructed. Ordinary billing or technical support is not an emergency-dispatch service.

Do not silence or dismiss a smoke, fire or carbon monoxide alarm until everyone is safe and the cause has been evaluated. Leave the property and call emergency services when there may be a real hazard.

Accidental or False Alarm

Follow the instructions for the specific panel, ADT app, monitoring call or secure Alarm Messenger session. Entering the security code within the allowed period may cancel some accidental alarms. When ADT calls, the account holder or approved emergency contact may need the verbal security password to verify identity.

Keep emergency contacts current in MyADT or the system’s account portal. Make sure each approved contact understands when ADT may call and how to use the verbal password without sharing it publicly.

Alarm Permits and False-Alarm Fees

Some cities and counties require alarm registration or permits and can charge fines for repeated false alarms. These are local-government rules, not policies created by CustomerServiceNumbers.com. ADT currently lists 1-888-392-2039 and permit@adt.com for permit assistance. Also check the police department, sheriff, city or county website serving the monitored address.

ADT Technical Support, Batteries, Cameras and Service Appointments

Start with the system panel troubleshooting page or search the ADT Help Center for the exact panel and message. ADT maintains different instructions for ADT+, Command, Control, Pulse, Self Setup, Blue and older systems.

• Beeping or low battery: Record the exact display and device. Silencing a trouble beep does not replace a failing battery or fix the underlying condition.
• Sensor offline or open: Identify the zone, door, window or device and check whether the issue began after a battery change, move or door adjustment.
• Camera or doorbell: Record whether live view, recording, notifications or Wi-Fi is failing. Check internet service and power before requesting a visit.
• App or login: Confirm whether the account uses MyADT, ADT+, ADT Control, ADT Pulse or a legacy Blue portal.
• Service appointment: Ask whether a visit fee, equipment cost, warranty or Quality Service Plan coverage applies.

Before a technician leaves, test the affected function, ask what was changed and keep the work-order notes. Do not publish camera screenshots, device serial numbers, alarm zones or a description of an unresolved security weakness.

MyADT, ADT+ and Monitoring Certificates

The ADT Customer Resources page routes customers to MyADT, ADT+, ADT Control and ADT Pulse. Use the portal tied to the actual system; credentials are not always interchangeable.

MyADT customers can access account documents and an Alarm Monitoring Certificate for an insurer. ADT+ users can find the certificate through the monitoring settings for supported systems. An insurer decides whether the certificate qualifies for a discount and how much that discount will be.

ADT Authorized Dealers and Deceptive Sales

An ADT logo or branded shirt does not prove that an unexpected visitor was assigned to the account. ADT specifically advises customers to verify a representative or work order through 1-800-238-2727 before allowing the person into the home.

• Do not sign an upgrade, takeover or replacement agreement based only on a door-to-door claim.
• Confirm whether the seller is ADT or an ADT Authorized Dealer and which company appears on the contract.
• Request the complete monthly cost, initial term, equipment terms, cancellation rules and installation charges in writing.
• Do not provide a verbal security password, alarm code, bank login, remote computer access or one-time code.
• Report a suspected deceptive sales incident to ADT and save doorbell footage, paperwork, names, phone numbers and vehicle information when safe to do so.

Use ADT’s official deceptive sales guidance for current reporting instructions.

How to Escalate an ADT Customer Service Complaint

1. Use the matching support route. Begin with billing, technical support, moving, permits or Self Setup rather than the corporate line.
2. Get a case number. Record the date, representative, department, promised action and expected completion date.
3. Request supervisor review. Explain what the first contact did, what remains unresolved and the exact outcome requested.
4. Send a written summary when needed. Include the case number, account identifier, timeline and copies of relevant contracts, bills, photos or service records. Do not email alarm codes or passwords.
5. Confirm cancellation and credits in writing. A verbal promise is difficult to prove if another bill appears.
6. Use the appropriate outside route. A deceptive sales complaint may be reported through the Federal Trade Commission’s ReportFraud portal or a state consumer-protection office. An unauthorized card transaction should be reported promptly to the card issuer after checking the ADT account and contract.

For formal legal notice, arbitration or small-claims procedures, read the specific ADT agreement and current legal terms. CustomerServiceNumbers.com does not provide legal advice and cannot determine whether a fee or contract is enforceable.

ADT Corporate Office

ADT Inc. is headquartered at 1501 Yamato Road, Boca Raton, FL 33431. Its corporate phone number is 1-561-988-3600.

ADT Customer Service Reviews on CSN

CustomerServiceNumbers.com currently shows one submission with a 3.0-out-of-5 rating on this ADT page. However, the text describes a retail checkout and appears to use “ADT” as a retail sales measurement rather than referring to ADT home security. It does not provide usable evidence about ADT monitoring, billing, installation, equipment, cancellation or customer service.

Because there is no clearly relevant ADT review in the current CSN module, this page does not claim a positive or negative ADT service trend. If you leave a review below, identify whether it involved billing, cancellation, monitoring, an alarm event, installation, moving, equipment, a technician, an authorized dealer, an app or escalation. Do not include private security or account details.

For additional independent ratings and complaint experiences, visit the ADT reviews and complaints page on ZeroStars. ZeroStars and CustomerServiceNumbers.com are independent sites and cannot view an ADT account, cancel monitoring, dispatch emergency services or issue a refund.

How do I cancel ADT monitoring?
