AT&T codes are special sequences of numbers and symbols (like the asterisk and pound sign $’#’$) that you can dial from your phone to instantly access self-service features, manage account details, and control call settings without having to navigate menus or speak to a representative. These are often referred to as Star Codes or Short Codes.
Whether you are looking to check your data usage, hide your Caller ID for a single call, or set up call forwarding, these dial codes are the quickest way to manage your AT&T mobile or digital phone service. This article breaks down the most useful AT&T codes for managing your account and enhancing your call privacy.

Device and International Codes
Universal Device Codes
These codes are standardized across almost all cellular networks and are not specific to AT&T, but are useful to know.
| Code | Purpose |
| *#06# | IMEI Number: Displays your device’s unique International Mobile Equipment Identity number. Essential for unlocking, insurance claims, or reporting theft. |
| *3001#12345#* | Field Test Mode (iPhone): Opens a hidden menu on an iPhone to check detailed network and signal information. |
| *#*#4636#*#* | Testing Menu (Android): Opens a testing menu on many Android devices to check phone, battery, usage, and Wi-Fi information. |
International Dialing Codes
When calling a number internationally from your AT&T phone, the country code is the most critical element.
- Exit Code (011): To place an international call from the U.S., always start by dialing 011 (the U.S. exit code).
- Example: To call a number in France, you would dial 011 + 33 (France’s Country Code) + the local number.
- AT&T Direct Access Codes: When traveling internationally and trying to call back to the U.S. using an AT&T Calling Card, you use a special AT&T Direct Access Code specific to the country you are in.
Frequently Asked Questions (FAQ)
What is the fastest way to check my AT&T data usage on my phone?
The fastest way to check your AT&T wireless data usage is to open your phone’s dialer app and dial the short code *3282# (which spells *DATA#). AT&T will send you an immediate text message detailing your usage.
Do I need to be an AT&T wireless customer for these codes to work?
Yes, most Star Codes and Short Codes (those beginning with or $’#’$) are specific Feature Access Codes programmed into the AT&T network. They will only function correctly when dialed from an active AT&T (Wireless or Digital Phone) service line. Universal codes like *#06# will work on any phone regardless of the carrier.
Why do some call forwarding codes have a ‘#’ at the end and others don’t?
The structure of the codes can vary depending on the exact service (e.g., landline, digital phone, or wireless) and the feature being activated. For example, many Digital Phone and U-Verse Voice services require the sign at the end to properly close the command, while some older, per-call wireless codes (like *67) do not. Always use the full sequence provided in the table for the best chance of success.
Will I be charged for dialing these short codes?
In almost all cases, no. Dialing self-service short codes and star codes (such as those to check data, balance, or manage call features) from your AT&T Wireless phone is typically free of charge and does not count against your plan’s minutes or usage. Calls to 611 for customer service are also free.
