Deactivating a USSD code or service depends on what kind of deactivation you are referring to—whether it is related to banking USSD codes, call forwarding, or hiding and showing your number. Below are the general steps and common codes used for each scenario:
1. Deactivating Your USSD Banking Profile
- If you want to disable your USSD access for mobile banking (for example, after losing your phone), most banks offer a specific USSD code you can dial from any phone to deactivate your profile. For example, to deactivate your number with First Bank Nigeria, dial *894*911# from any device, and follow the on-screen prompts[5]. Other banks have similar codes such as *901*911# for Access Bank and *966*911# for Zenith Bank[7].
- If you wish to turn off USSD banking entirely, some banks or platforms allow you to toggle the USSD option on or off within their mobile app or web portal under the Settings menu[4].
2. Disabling Call Forwarding or Call Diversion via USSD
- To deactivate conditional call forwarding, dial ##61# on your phone[2].
- To deactivate all forms of call diversion, dial ##002# as a universal code[2].
- To erase all conditional forwarding settings, use ##004# as the deactivation code[2].
- Note: Some codes may not work on all networks and depend on your carrier’s support[2].
3. Deactivating Caller ID Hiding (Private Number)
- To stop hiding your outgoing number (i.e., disable private number), dial #31# and your number will show normally to recipients[3].
General Notes:
- The process may vary depending on your network, bank, or country. If in doubt, contact your bank or cellular provider’s customer support for precise instructions.
- If your phone is blocking USSD codes due to a security feature (such as Auto Blocker), go to Settings > Security and Privacy > Auto Blocker and turn it off, but review what the Auto Blocker does before disabling as this is a security measure[1].
