Comprehensive List of AT&T USSD Codes in the Year 2022
In the rapidly evolving world of telecommunications, AT&T has made it easier for its customers to manage their calling features directly from their devices. By utilising USSD (Unstructured Supplementary Service Data) codes and star codes, AT&T subscribers can activate and deactivate various calling features without the need for lengthy phone calls to customer support.
To activate a function, simply input the corresponding code and either hit the Dial soft key or the number (#) key. For instance, to reach AT&T customer support directly, dial 611 from your AT&T phone. If you need to check your balance (for prepaid accounts), dial 777#. To view your data and minutes usage, dial 646#.
Functionality can be changed using star codes or through the AT&T Phone Portal. However, the method of activation may vary depending on the phone's manufacture and version. In such cases, the current call is placed on hold, and a new call is started by clicking a line key.
Here's a list of common AT&T USSD codes for customer service and feature activation:
- Customer service quick access: Dial 611 from your AT&T phone to reach AT&T customer support directly.
- Check balance: Dial *777# (for prepaid accounts).
- View data and minutes usage: Dial *646#.
- Call forwarding activation: Dial 72 to turn on call forwarding, and 73 to deactivate it.
- Call waiting activation: Dial *43 to activate and #43# to deactivate call waiting.
- Caller ID blocking for a single call: Dial *31# before the number.
- Check call forwarding status: Dial *#21#.
- Disable all call forwarding: Dial ##002#.
For more extensive call management features (like call blocking up to 100 numbers, call trace, three-way calling, etc.), AT&T U-verse or home phone customers have specific star codes detailed on AT&T support pages.
In addition to USSD codes, AT&T also provides a set of star codes for various calling features, mostly for home phones. Here's a table summarising some of these codes:
| Feature | Activation Code | Deactivation Code | |--------------------------|----------------------|----------------------| | Call Forwarding | 72 or 72# | 73 or 73# | | Call Return (redial last call) | 69 | (Not applicable) | | Call Waiting | 43 | #43# | | Caller ID Blocking | *31# (single call) | (Not applicable) | | Anonymous Call Rejection | (Depends on account) | (Depends on account) |
Please note that the availability of some features and codes can depend on your service plan and area. Some codes work only on home phones or postpaid plans.
For direct customer support to discuss accounts or activate features if USSD codes are insufficient, dial 611 from your AT&T mobile phone.
