AT&T Dallas Headquarters and Future Plano Move

AT&T’s official headquarters mailing address remains 208 S. Akard Street in Dallas, Texas. This address is associated with AT&T’s downtown Dallas headquarters, also known as Whitacre Tower and the AT&T Discovery District.

Until AT&T updates its official corporate mailing address, customers, investors, and consumers should use the current Dallas headquarters address listed by AT&T for corporate correspondence.

Do not mail payments, devices, trade-ins, legal notices, fraud documents, or account paperwork to the corporate office unless AT&T specifically instructs you to do so. Use the mailing address or upload instructions shown on your bill, return label, fraud form, Notice of Dispute form, or other official AT&T document.

Choose the Correct AT&T Support Route

AT&T has different support paths depending on whether the issue involves wireless, prepaid, internet, fiber, TV, landline, business service, fraud, or a formal dispute.

Customers should use the phone number on their bill, account portal, wireless device, order confirmation, claim form, or dispute notice when it differs from a general number shown online.

What to Have Before Contacting AT&T

AT&T may require account verification before discussing billing, wireless, internet, device, fraud, cancellation, or dispute details.

• AT&T account number
• Account PIN or passcode
• Phone number or service address involved

• Store location and receipt, when applicable
• Dates and times of prior calls, chats, or store visits

AT&T Wireless, Device and Account Complaints

Wireless complaints may involve activation, phone upgrades, eSIM setup, SIM cards, device trade-ins, promotion credits, rebates, insurance or protection plans, international roaming, number transfers, connected devices, tablets, smartwatches, data plans, suspended service, or store promises that do not appear on the account.

When contacting AT&T about a wireless issue:

1. Confirm which line, device, or account is affected.
2. Check whether the account is current and active.
3. Save screenshots of promotions, device agreements, trade-in terms, and monthly credits.
4. Ask whether the issue involves the device, SIM/eSIM, network, account settings, billing system, order, or store transaction.
5. Request written confirmation of any promised credit, exchange, replacement, rebate, or correction.
6. Review the next bill to confirm that the adjustment actually posted.

Customers with device setup problems should confirm whether the issue must be handled by AT&T, the device manufacturer, the original retailer, Apple, Samsung, Google, a protection plan, or the store that performed the setup.

AT&T Billing, Payment and Collection Complaints

Billing complaints may involve unexpected charges, missing credits, duplicate payments, AutoPay issues, late fees, returned payments, suspended service, device installment balances, final bills, collections, payment arrangements, taxes, fees, bundled services, or promotional discounts that did not apply.

When disputing an AT&T bill:

1. Download the current bill and the prior bill.
2. Compare each line, device payment, service, tax, fee, discount, and promotional credit.
3. Identify the exact dollar amount in dispute.
4. Check whether the issue involves wireless, internet, TV, landline, prepaid, business, or a third-party product.
5. Ask AT&T to explain the charge and provide a case number.
6. Request written confirmation of any payment arrangement, credit, refund, or correction.
7. Keep proof of payment and all emails, chats, and call records.
8. Review the next bill to confirm that the correction was applied.

Do not assume that a promised credit is complete until it appears on the account or final bill.

AT&T Internet, Fiber, TV and Landline Issues

AT&T internet, fiber, TV, and landline complaints may involve outages, slow speeds, installation delays, fiber construction, gateway equipment, technician visits, missed appointments, buried lines, property damage, unreturned equipment fees, cancellation, or billing problems.

For internet, TV, or landline issues, call 1-800-288-2020.

Before contacting AT&T about a home-service issue:

• Check whether there is a known outage.
• Document speed tests at different times of day.
• Record whether the issue affects Wi-Fi, wired internet, TV, phone, or all services.
• Save technician appointment confirmations.
• Photograph line, equipment, property, or installation damage when relevant.
• Keep equipment return receipts and tracking numbers.
• Ask whether a technician visit could result in a charge.
• Request a ticket number for unresolved repair or installation issues.

If a technician charge, missed appointment, property damage, or unreturned-equipment fee appears unexpectedly, ask AT&T to review the original service order, technician notes, equipment serial numbers, return receipt, and account notes.

AT&T Fraud, Unauthorized Accounts and Account Security

AT&T provides specific fraud-reporting resources for unauthorized wireless accounts, unauthorized account changes, identity theft, unauthorized internet or phone accounts, suspicious calls, phishing emails, and scam texts.

Contact AT&T promptly if:

• You find an AT&T account on your credit report that you did not open.
• A collection agency contacts you about an AT&T account you do not recognize.
• An unauthorized line or device appears on your account.
• Your account email, PIN, passcode, or contact information changes without permission.
• Your phone number is transferred or your SIM/eSIM changes without authorization.
• You receive a suspicious AT&T email, text, or phone call.
• You see charges, devices, accessories, or plan changes you did not approve.

For wireless fraud, use the AT&T Wireless Fraud page or call 1-877-844-5584.

For voice or internet fraud, use AT&T’s Voice and Internet Fraud resources or call 1-877-379-2319.

If identity theft is involved, consider filing an identity-theft report with the FTC and placing a fraud alert with the credit bureaus.

AT&T Phishing, Scam Calls and Suspicious Messages

Scammers frequently impersonate AT&T through calls, texts, emails, search ads, social-media messages, fake support websites, and fake reward or bill-credit offers.

Common AT&T-related scams may include:

• Fake account-suspension notices
• Fake bill-credit links
• Fake device-upgrade offers
• Requests for account PINs or one-time codes
• Messages claiming a payment failed
• Fake rewards or survey offers
• SIM-swap or port-out warnings sent from suspicious links
• Calls that spoof AT&T’s real phone numbers
• Requests to pay with gift cards, crypto, wire transfers, or unfamiliar payment apps

AT&T says suspicious emails that appear to come from AT&T can be forwarded to ab***@*tt.net.

Do not call a number or click a link from an unexpected message. Open AT&T directly through the official app or website, or call a verified AT&T number.

AT&T Stores and Authorized Retailer Complaints

AT&T complaints may involve a company-owned store, authorized retailer, third-party seller, online order, or in-home sales representative. The type of sales channel can affect who has authority to correct the problem.

Store-related complaints may involve:

• Promotion promises
• Trade-in values
• Device setup
• Data transfer problems
• Activation fees
• Accessory charges
• Device insurance or protection plans
• Device returns
• Restocking fees
• Unauthorized add-ons
• Employee conduct
• In-home sales or installation promises

Keep the receipt, store location, employee name or manager name, order number, and any written promotion terms. Ask whether the location is a corporate AT&T store or an authorized retailer before escalating the issue.

AT&T Notice of Dispute and Formal Escalation

AT&T provides a Notice of Dispute process for customers who have not resolved an issue through ordinary support. AT&T says a representative will investigate and contact the customer within 60 days to work toward a resolution.

Use ordinary AT&T support first if you need immediate billing, wireless, internet, payment, repair, device, fraud, or account help.

For formal dispute escalation:

1. Use the correct AT&T support route first.
2. Keep all case numbers, bills, receipts, chats, emails, and letters.
3. Prepare a concise timeline of the problem.
4. Identify the account, service, dollar amount, and resolution requested.
5. Submit AT&T’s Notice of Dispute form if ordinary support does not resolve the matter.
6. Keep a complete copy of the submitted form and supporting records.
7. Watch for AT&T’s response during the informal dispute-resolution period.

AT&T’s Notice of Dispute form directs completed forms and supporting documents to:

Follow the current instructions on AT&T’s official form because the required process may differ by service, agreement, account type, and dispute category.

How to Escalate an AT&T Complaint

1. Identify the service involved. Determine whether the issue is wireless, prepaid, internet, fiber, TV, landline, business, fraud, store-related, or billing-related.
2. Contact the correct department. Use the wireless, prepaid, internet, business, fraud, or store route that matches the issue.
3. Ask for a case number. Record the representative’s name, date, time, department, and explanation.
4. Request supervisor review. Clearly state what remains unresolved and what resolution you want.
5. Use written records. Save bills, receipts, screenshots, chat transcripts, tracking numbers, repair tickets, and store paperwork.
6. Secure the account if fraud is involved. Change passwords, review account access, update passcodes, and contact banks or email providers if a phone number was compromised.
7. Use AT&T’s Notice of Dispute process. For unresolved formal disputes, use the official Notice of Dispute process and follow the required waiting period.
8. Consider outside complaint options. Wireless, broadband, billing, number-transfer, fraud, and property-damage complaints may involve the FCC, FTC, state attorney general, state consumer-protection office, 811 utility-damage process, local authorities, or payment-card issuer depending on the issue.
