What are USSD Codes?
USSD (Unstructured Supplementary Service Data) uses codes made up of the characters available on a mobile phone. A USSD message can be up to 182 characters long and allows for real-time communication between the phone and another device, usually a network or server.
In general, they are “Quick Codes”; they are sort of predefined numbers that users can send, and in response, the carrier network system sends a text message containing the requested information. Ideally, each telecom operator has a list of these codes.
Let’s understand how they look like.
Generally, the USSD code contains ‘*’ or ‘#’ symbols and includes a combination of numbers in the middle. Therefore, anyone can easily identify the USSD code that comes from the normal number.
Benefits of USSD codes

- Only prepaid users can take a data loan. Postpaid users are not eligible.
- Airtel charges ₹20 for a 200MB loan and ₹50 for a 500MB loan as a service fee, deducted during your next recharge.
- For Jio, prepaid users can borrow 1GB to 2GB of data, and prices range from ₹11 to ₹25 per 1GB.

How USSD Works
USSD (Unstructured Supplementary Service Data) is a way for mobile phone users to send and receive information in real time. Let me explain how it works in detail:
User Sends a Request: A mobile phone user wants to do something like check their bank account balance. They send a request by dialing a special code (usually five numbers) on their phone.
Request Goes to USSD Gateway: The request is sent to a system called the USSD gateway.
USSD Gateway Forwards the Request: The gateway sends the request to the specific USSD application that can handle it. For example, the bank’s application that checks account balances.
USSD Application Responds: The USSD application processes the request and prepares a response.
Response Goes Back to Gateway: The response from the USSD application is sent back to the USSD gateway.
Gateway Displays Response: The USSD gateway sends the response back to the user’s mobile phone, where it is displayed on the screen.
How do USSD Code Differs From an SMS Service?
If you’re thinking USSD code and SMS service are similar, you’re mistaken. Both are significantly different. USSD codes come from the real-time connection. Whenever you apply the USSD code on your device, the communication channel opens up. It supports two-way communication. Therefore, it is more responsive than the normal SMS platform.
Differences Between USSD, MMI, and SS Codes
Man-Machine Interface (MMI) Codes
MMI codes are special codes that users enter on their mobile phones using the keypad, which include * or # characters. These codes can perform various functions and are classified into different groups:
- Supplementary Service (SS) Codes
- Purpose: Control call forwarding and number presentation.
- Example: 21987654321# <SEND> – This code tells the phone to ask the network to forward all incoming calls to the number 987654321.
- How It Works: The phone interprets the code and constructs a request to the network.
- Characteristics: These codes are hardcoded into every GSM, UMTS, and LTE device and cannot be changed by network operators.
- USSD Codes
- Purpose: Enable real-time communication between the phone and the network.
- Example: *#100# <SEND> – Commonly used to check prepaid card balances.
- How It Works: If the code ends in # and is not recognized by the phone’s MMI interpreter, it is sent to the network to be processed.
- Characteristics: The network decides which codes to support.
- Manufacturer-Defined MMI Codes
- Purpose: Activate service menus or reset devices, specific to phone models.
- Example: *#06# – Displays the device’s International Mobile Equipment Identity (IMEI).
- How It Works: These codes are executed as soon as the last digit or character is entered, without needing to press <SEND>.
- Characteristics: Not sent to the network and are specific to the manufacture.

Quick Fixes if USSD Codes Not Working
Sometimes USSD codes show an error or simply don’t respond. In such a situation, you can try the following fixes.
1. Check the code carefully. Make sure you have the * at the start and # at the end. Even a small typo will make it fail.
2. Restart your phone. A quick restart clears network glitches that can block USSD codes.
3. Check your SIM slot. On dual-SIM phones, USSD codes only work from the active SIM slot (usually SIM 1). Switch to the correct SIM before dialling.
4. Wait and retry. Network maintenance or server issues can temporarily block codes. Wait 20–30 minutes and try again.
5. Call customer care. If nothing works, call your operator directly — Airtel (121), Jio (199), Vi (199), or BSNL (1503).
Remember, USSD codes work even without a data connection or internet. So they’re your best friend when your data pack is empty, and you can’t open any apps.
Conclusion
Thus, having a full list of USSD codes for major Indian telecom networks like Airtel, BSNL, Vi, and Jio is very useful. These codes allow users to quickly get important information about their mobile services, check their balances, find new offers, and manage other mobile features. By knowing and using these codes, you can easily keep track of their mobile usage and handle their services smoothly, making their mobile experience more convenient.
