Post: 10 Powerful Phone Codes for Android & iPhone You’ll Love
Secret Phone Codes You Can Actually Use: Hidden Tools for Android and iPhone Users
Most people don’t realize that their smartphones come loaded with a hidden layer of functionality — and you don’t need an app to access it. Just by dialing certain short strings of numbers and symbols (usually starting with * or #), you can unlock secret menus, check your phone’s status, adjust carrier settings, or access diagnostic tools. These are often referred to as USSD codes, MMI codes, or simply phone codes — and they’re built right into your device’s software.
We ran a full test of these codes across both Android and iPhone, checking how they behave on different devices and mobile networks. Some are incredibly handy for everyday use — like checking your data balance, finding your IMEI number, or confirming if call forwarding is enabled. Others go deeper, pulling up engineering dashboards or signal strength data meant for developers and technicians. And yes, a few are risky — one code can trigger a full factory reset with no warning. So proceed with caution, especially if you’re just experimenting.
Below, we’ve compiled the most useful, powerful, and potentially dangerous phone codes in one place. Each one is labeled clearly so you know what it does, whether it works on iPhone, Android, or both, and whether it’s carrier-specific. Use this guide to take better control of your phone — or just to geek out on how much it can really do.

❓ FAQs
Q: What’s the difference between phone codes and short codes?
They’re essentially the same thing. Carriers might call them “short codes,” but whether it starts with * or #, they do similar things.
Q: Will all these codes work on my phone?
Not always. Some are Android-only, some iPhone-only, and many are carrier-specific.
Q: Can I break my phone using these codes?
Most are safe. The factory reset code is the only one that poses real risk—and only if you use it intentionally.
Q: What if I mess something up?
You can usually fix it in Settings or by entering the reverse code. When in doubt, back up your data.
Whether you’re checking your data usage, forwarding calls, or pulling up your IMEI, these hidden phone codes offer fast, direct access to features that are often buried in settings menus. From powerful USSD codes provided by carriers to secret engineering menus built into your device, this list covers practical tools for both Android and iPhone users. While many of these codes are perfectly safe and useful, some—like the factory reset code—should only be used with caution. Knowing the right codes can save you time, help you troubleshoot faster, and give you greater control over your mobile experience.
