Last updated September 29, 2026
The AT&T customer service number is 800-331-0500 for wireless accounts (or 611 from an AT&T phone) and 800-288-2020 for AT&T Internet, AT&T Fiber, and Internet Air. Agents on both lines answer Monday through Friday from 8 a.m. to 8 p.m. Central and Saturday from 9 a.m. to 7 p.m. Central. The wireless line is also staffed on Sunday.
This guide lists every current AT&T support number with its hours, the fastest ways to reach a person, how live chat and social media support work, and where to take a problem when the first call does not fix it. Numbers and hours were checked against AT&T's own support pages on September 29, 2026.
Key Takeaways
- Wireless: 800-331-0500 or 611. Internet, Fiber, and Internet Air: 800-288-2020. AT&T Prepaid: 800-901-9878.
- AT&T agents are not available around the clock. Most lines close at 8 p.m. Central on weekdays, and internet billing support is closed on Sunday.
- Only dial numbers printed on att.com, your bill, or the myAT&T app. Search results for AT&T support include look-alike numbers that do not belong to AT&T.
- The AT&T Community Forums closed in June 2024. Phone, chat, the myAT&T app, and @ATTHelp on X are the current support channels.
- If AT&T does not resolve a billing or service problem, an informal complaint to the FCC costs nothing and requires AT&T to respond in writing within 30 days.

How to Reach a Live Person at AT&T
Every AT&T line starts with an automated system. These habits shorten the trip to an agent:
- Call during agent hours. Outside the hours in the table above, the automated system still answers, but no one is available to pick up. Internet cancellation requests received while AT&T is closed are handled on the next business day.
- Call from the phone on the account, or have the account number ready. The system tries to look up your account from the number you are calling from. If that fails, you will be asked for the account number printed on your bill.
- Say the reason in a few words. "Billing dispute," "technical support," or "cancel service" routes faster than a long explanation. If the system keeps offering self-service options, say "representative."
- Know your account PIN or passcode. AT&T asks for it before making account changes, and only the account owner can cancel internet service.
- Take the callback. For technical support, AT&T's service guarantee promises an expert within five minutes or a scheduled callback at a time you choose. A callback beats sitting on hold.
- Turn off Wireless Account Lock first. If you enabled this security feature, some wireless changes are blocked until you switch it off in the myAT&T app.
- Keep a record. Write down the date, the agent's name, and any reference or confirmation number before you hang up.
Make Sure the Number You Dial Belongs to AT&T
When we searched for AT&T support numbers in September 2026, the results included PDF pages hosted on unrelated university and government websites, written to look like help articles and listing a toll-free number that appears nowhere on att.com. Pages like these exist to get you to call someone who is not AT&T.
- Dial only numbers shown on att.com, your AT&T bill, or the myAT&T app. Every number in the table above comes from AT&T's own support pages.
- If someone calls you claiming to be AT&T and asks for a password, PIN, or payment, hang up and call the number on your bill.
- AT&T's guide to phishing and fake websites explains how to report a suspicious message or site.
Live Chat, the myAT&T App, and Social Media
Live chat
Go to AT&T's Contact us page, choose your service, and scroll to "Chat with a rep." The chat opens with a few automated questions before handing you to an agent. AT&T describes chat as something to use "when available," so if the option does not appear, try again during phone hours.
AT&T Prepaid has its own text-based chat: text the word prepaid to 75421. It runs Monday through Saturday from 9 a.m. to 11 p.m. Eastern and Sunday from 10 a.m. to 11 p.m. Eastern.
myAT&T app and Smart Home Manager
The myAT&T app handles most account tasks without a call: viewing and paying a bill, checking usage, changing a plan, and tracking an order. Internet customers also get the Smart Home Manager app, which shows your WiFi details, checks service status, and tests your equipment.
X (formerly Twitter)
AT&T's support account on X is @ATTHelp. Use a direct message for anything tied to your account, and never post an account number, address, or PIN in a public reply.
Community forums and email
The AT&T Community Forums were shut down on June 27, 2024, so older advice to post a question there no longer applies. AT&T also does not list a public support email address. Its contact page offers phone and chat only.
Getting Help at an AT&T Store
Use the AT&T store locator to find a location. Stores are most useful for wireless needs: new phones, upgrades, plan changes, and device returns. If you picked up an online order in a store and return it within the 14-day window, the store can waive the restocking fee. Bring a government-issued photo ID that matches the name on the account.
Internet equipment is different. AT&T's return instructions send gateways and extenders to The UPS Store or a company-owned FedEx Office location, not to an AT&T retail store. The cancellation section below covers how that works.
Fixes to Try Before You Call About Internet Problems
Many internet support calls end with one of these steps, so trying them first can save the hold time:
- Check for an outage. Enter your address at att.com/outages. If AT&T already knows about a problem in your area, a call will not speed up the repair.
- Restart the gateway. Unplug the power cord from the back of the gateway, wait about 20 seconds, and plug it back in. It can take up to 10 minutes to come fully back online. AT&T's restart instructions cover each model.
- Read the lights. The status light tells you whether the fault is the line, the gateway, or your WiFi. AT&T publishes a light guide for its gateways.
- Run the Smart Home Manager check. The app tests your connection and equipment and can tell you whether the problem is inside or outside your home.
If the connection at the gateway is fine but the WiFi is weak in parts of the house, the fix is often better WiFi equipment rather than a support call. AT&T requires its own gateway, but you can plug your own router or mesh system into it. Our guide to activating AT&T internet equipment explains how the gateway and a third-party router work together.

What the AT&T Guarantee Means for Support Calls
AT&T launched a service promise called the AT&T Guarantee in January 2025. Three parts of it matter when you contact support:
- Outage credits. If an AT&T Fiber or Internet Air network interruption lasts 20 minutes or more, AT&T credits a full day of service. Qualifying wireless outages of 60 minutes or more earn a credit as well.
- Wait time. For technical support, AT&T promises an expert within five minutes or a callback at a time you choose. The five minutes start once you are routed to technical support.
- Technician visits. Fiber customers are promised same-day or next-day technician appointment availability.
Restrictions and exclusions apply, including outages caused by weather. If you are calling about an outage, ask the agent whether it qualifies.
What to Do If AT&T Does Not Fix the Problem
When a first call does not resolve a billing error or a service problem, work up in this order:
- Call back with your record. Give the new agent the date, name, and reference number from the earlier call, and ask for a supervisor if the answer is the same.
- Put it in writing through chat. A chat transcript gives you a written record of what AT&T agreed to.
- File an informal complaint with the FCC. The FCC Consumer Complaint Center accepts complaints about phone and internet billing and service. There is no filing charge. The FCC serves the complaint on AT&T, and AT&T is required to respond in writing within 30 days and send you a copy. You can also file by phone at 888-225-5322.
- Contact your state. The FCC notes that some issues are better handled by state or local agencies, such as a public utility commission or the attorney general's consumer office.
Canceling AT&T Service
The short version for each service:
- Internet, Fiber, and Internet Air. The account owner calls 800-288-2020 during agent hours with the account number and PIN. You can cancel within 14 days of activation without an early termination fee. After that, a fee applies only if your plan has a term commitment.
- Equipment. Return the gateway, any AT&T extenders, and the power supplies undamaged within 21 days. The non-return fee is $150, and AT&T refunds it if the equipment arrives within six months. Take the unboxed equipment and your account number to The UPS Store or a company-owned FedEx Office, have a store employee scan it, and keep the receipt. Do not use a drop box, and leave wall-mounted equipment such as the fiber jack or ONT in place.
- Wireless. Use chat when it is available or call 800-331-0500. Any remaining device installment balance comes due on your next bill. Some accounts can submit a cancel request online.

If you are moving to a cable or DSL provider, this is the moment to stop renting equipment. Most of those providers let you use a modem you own.
