AT&T's main customer service number is 611 from any AT&T phone, or 1-800-331-0500 from any phone

The fastest way to reach AT&T depends on what you need. If you are calling from an AT&T mobile phone, dial 611 and you will reach customer service without using your minutes. If you are calling from another phone or a landline, use 1-800-331-0500. Both numbers connect you to the same support team and have the same wait times.

AT&T also maintains separate phone lines for different types of accounts. If you have AT&T internet or TV service, you can reach that department at 1-800-288-2020. If you have AT&T wireless and another service bundled together, calling 611 or 1-800-331-0500 will route you to the right department based on what you say when the automated system answers.

Key Takeaways

  • Dial 611 from your AT&T mobile phone to reach customer service without using minutes or data.
  • Call 1-800-331-0500 from any other phone to reach the same AT&T wireless support team.
  • AT&T internet and TV customers should call 1-800-288-2020 instead, as that line handles those services.
  • The automated system will ask what you need before connecting you to a representative, so have your account number or phone number ready.

What to have ready before you call

AT&T's automated system asks questions to route your call to the right department. Have your phone number or account number available so the system can pull up your account faster. If you are calling about a specific bill or charge, have that bill in front of you.

If you are calling about a problem with your phone or service, write down what is happening before you call — for example, "calls drop after 30 seconds" or "data is slower than usual." This helps the representative understand the issue without having to ask you to repeat yourself multiple times.

Wait times and when to call

AT&T does not publish official wait time data, but customer reports suggest that wait times are shortest on weekday mornings between 8 a.m. and 10 a.m., and longest on weekday evenings and weekends. If your issue is not urgent, calling on a Tuesday or Wednesday morning may mean a shorter hold.

If you are in a situation where you cannot wait on hold — for example, you are calling from a phone with low battery — ask the automated system to schedule a callback instead. AT&T will call you back at the number you provide within a set window, usually the same day or next business day.

Other ways to reach AT&T

AT&T offers support through channels other than phone. You can message AT&T through their website at att.com, use the AT&T mobile app to chat with a representative, or visit a physical AT&T store to speak with someone in person. The app also lets you manage your account, pay your bill, and check your data usage without calling.

For billing questions, you can also call the billing department directly at 1-800-331-0500 and tell the automated system you have a billing question. This sometimes routes you faster than the general customer service line.

What AT&T phone numbers do and do not handle

AT&T's main customer service lines handle account changes, billing questions, service problems, phone upgrades, and plan changes. They can also help if you have lost your phone or need to report fraud on your account.

Some issues require a different department. If you need to report a phone as stolen or lost and want it blocked when ready, you can also text STOP to 411411 from any phone to reach AT&T's security team. If you have a problem with a bill you believe is wrong, the representative can start an investigation, but you may need to follow up in writing for formal disputes.

International calling and roaming support

If you are traveling outside the United States and need to reach AT&T, you can call the same 1-800-331-0500 number from most countries, though international calling rates will explore. AT&T also has a dedicated international support line: 1-908-559-4899, which you can call from abroad.

Before traveling, you can also call 611 or 1-800-331-0500 from home to set up your international plan or ask about roaming rates in the country you are visiting. Representatives can add temporary international passes to your account before you leave, which is often cheaper than paying per-use rates.

Frequently Asked Questions

Will I be charged for calling 611 from my AT&T phone?

No. Calls to 611 do not count against your minutes or data, and AT&T does not charge a fee for customer service calls. This is true even if you are on a limited plan.

What if I am having trouble reaching a person?

If the automated system keeps disconnecting you or routing you incorrectly, try calling back at a different time or use the callback feature instead of waiting on hold. You can also try the AT&T app or website to chat with a representative, which sometimes has shorter wait times than phone lines.

Can I reach AT&T through social media?

Yes. AT&T monitors messages on Facebook and Twitter and responds to customer service requests. Sending a direct message to @ATT on Twitter or messaging AT&T's Facebook page can sometimes get you a response faster than calling, especially during peak hours.

What if I need to reach AT&T about a business account?

AT&T business customers have a separate support line at 1-800-331-0500, but you can also reach business support at 1-866-429-2700. Have your business account number ready when you call.
