Are you tired of receiving unwanted calls from unknown numbers or pesky telemarketers? Look no further! In this article, we will explore the world of USSD codes and how you can use them to block unwanted numbers on your mobile phone. USSD (Unstructured Supplementary Service Data) codes are a quick and easy way to manage your mobile phone settings, including blocking unwanted calls.
What are USSD Codes?
USSD codes are a series of numbers that you can dial on your mobile phone to access various services and settings. They are usually preceded by an asterisk (*) and followed by a hash (#) symbol. USSD codes can be used to perform a variety of tasks, such as checking your account balance, activating or deactivating services, and even blocking unwanted calls.
How Do USSD Codes Work?
When you dial a USSD code on your mobile phone, it sends a request to your network provider’s server. The server then processes the request and sends a response back to your phone. This response can be in the form of a menu, a message, or even a change in your phone’s settings.
Blocking Unwanted Calls with USSD Codes
To block an unwanted number using a USSD code, you will need to follow these steps:
Step 1: Check if Your Network Provider Supports USSD Codes
Not all network providers support USSD codes, so it’s essential to check with your provider before attempting to use them. You can usually find this information on your provider’s website or by contacting their customer service.
Step 2: Find the USSD Code for Blocking Unwanted Calls
The USSD code for blocking unwanted calls varies depending on your network provider. Here are some common USSD codes used by popular network providers:
| Network Provider | USSD Code |
|---|---|
| MTN | *61* |
| Airtel | *62* |
| Vodafone | *67* |
| AT&T | *60* |
| Verizon | *67* |
Step 3: Dial the USSD Code
Once you have found the USSD code for your network provider, dial it on your mobile phone. Make sure to include the asterisk (*) and hash (#) symbols.
Step 4: Enter the Number You Want to Block
After dialing the USSD code, you will be prompted to enter the number you want to block. Enter the number, including the country code and area code.
Step 5: Confirm the Block
Once you have entered the number, you will be asked to confirm the block. Select “Yes” or “Confirm” to block the number.
Alternative Methods for Blocking Unwanted Calls
If your network provider does not support USSD codes or if you prefer not to use them, there are alternative methods for blocking unwanted calls. These include:
Using Your Phone’s Built-in Call Blocking Feature

Using a Third-Party Call Blocking App
There are many third-party call blocking apps available for download on the App Store or Google Play Store. These apps can provide additional features such as call filtering and blocking of unknown numbers.

How do I block a number using USSD codes?
To block a number using USSD codes, you will need to dial a specific code followed by the number you wish to block. The exact code may vary depending on your mobile network, so it’s essential to check with your network provider for the correct code. Typically, you will need to dial a code such as *35* followed by the number you want to block, and then press the call button. You may also need to confirm that you want to block the number by responding to a prompt or entering a confirmation code.
Once you have blocked a number using a USSD code, the caller will typically receive a message indicating that their call has been blocked or that your number is not available. You can also use USSD codes to unblock numbers that you have previously blocked, by dialing a different code or following a specific procedure. It’s essential to note that some mobile networks may have different procedures for blocking and unblocking numbers, so be sure to check with your network provider for specific instructions.
Can I block multiple numbers at once using USSD codes?
Yes, it is possible to block multiple numbers at once using USSD codes, although the exact procedure may vary depending on your mobile network. Some networks allow you to block multiple numbers by separating them with commas or by dialing a specific code followed by the numbers you want to block. For example, you might dial *35*1234567890,1234567891,1234567892 to block three numbers at once.
However, it’s essential to note that some mobile networks may have limits on the number of numbers you can block at once, or may require you to block numbers individually. Additionally, some networks may offer more advanced call blocking features, such as the ability to block numbers based on specific criteria or to create a block list of numbers that are automatically blocked. Be sure to check with your network provider for specific instructions on blocking multiple numbers using USSD codes.
How do I unblock a number that I previously blocked using USSD codes?
To unblock a number that you previously blocked using USSD codes, you will typically need to dial a specific code followed by the number you want to unblock. The exact code may vary depending on your mobile network, so it’s essential to check with your network provider for the correct code. For example, you might dial *35* followed by the number you want to unblock, and then press the call button.
Alternatively, some mobile networks may allow you to unblock numbers by accessing your call settings menu or by using a specific USSD code to manage your block list. Be sure to check with your network provider for specific instructions on unblocking numbers using USSD codes. Once you have unblocked a number, the caller will be able to reach you again, and you will receive their calls as usual.
Can I block calls from private or unknown numbers using USSD codes?
Yes, it is possible to block calls from private or unknown numbers using USSD codes, although the exact procedure may vary depending on your mobile network. Some networks offer a feature that allows you to block calls from private or unknown numbers, which can be activated by dialing a specific USSD code. For example, you might dial *77* to block calls from private numbers, or *78* to block calls from unknown numbers.
However, it’s essential to note that blocking calls from private or unknown numbers may also block calls from legitimate callers who are not displaying their number, such as emergency services or healthcare providers. Additionally, some mobile networks may not offer this feature, or may require you to activate it through your call settings menu rather than using a USSD code. Be sure to check with your network provider for specific instructions on blocking calls from private or unknown numbers using USSD codes.
Will blocking a number using USSD codes also block text messages from that number?
Blocking a number using USSD codes may not necessarily block text messages from that number, depending on your mobile network and the specific code used. Some networks may only block voice calls from the number, while allowing text messages to be received as usual. In other cases, blocking a number using a USSD code may also block text messages from that number, but this is not always the case.
If you want to block both voice calls and text messages from a specific number, you may need to use a different USSD code or activate a separate feature through your call settings menu. Be sure to check with your network provider for specific instructions on blocking text messages using USSD codes, as the procedure may vary depending on your mobile network and the type of phone you are using.
Are there any limitations or restrictions on using USSD codes to block unwanted calls?
Yes, there are some limitations and restrictions on using USSD codes to block unwanted calls. For example, some mobile networks may limit the number of numbers you can block using USSD codes, or may require you to block numbers individually rather than in bulk. Additionally, some networks may not support USSD codes for call blocking, or may require you to use a different method to block unwanted calls.
Furthermore, USSD codes may not be effective in blocking calls from spoofed or fake numbers, as these calls may not be recognized by the network as coming from a blocked number. In such cases, you may need to use additional measures to block unwanted calls, such as registering your number on a national do-not-call list or using a third-party call blocking app. Be sure to check with your network provider for specific information on the limitations and restrictions of using USSD codes to block unwanted calls.
