[ios] Programmatically get own phone number in iOS

Is there any way to get own phone number by standard APIs from iPhone SDK?

Update: capability appears to have been removed by Apple on or around iOS 4

Just to expand on an earlier answer, something like this does it for me:

NSString *num = [[NSUserDefaults standardUserDefaults] stringForKey:@"SBFormattedPhoneNumber"];

Note: This retrieves the "Phone number" that was entered during the iPhone's iTunes activation and can be null or an incorrect value. It's NOT read from the SIM card.

At least that does in 2.1. There are a couple of other interesting keys in NSUserDefaults that may also not last. (This is in my app which uses a UIWebView)

WebKitJavaScriptCanOpenWindowsAutomatically
NSInterfaceStyle
TVOutStatus
WebKitDeveloperExtrasEnabledPreferenceKey

and so on.

Not sure what, if anything, the others do.

Using Private API you can get user phone number on the following way:

extern NSString* CTSettingCopyMyPhoneNumber();


+(NSString *) phoneNumber {
NSString *phone = CTSettingCopyMyPhoneNumber();

return phone;
}

Also include CoreTelephony.framework to your project.

No, there's no legal and reliable way to do this.

If you find a way, it will be disabled in the future, as it has happened with every method before.

AppStore will reject it, as it's reaching outside of application container.

Apps should be self-contained in their bundles, and may not read or write data outside the designated container area

Section 2.5.2 : https://developer.apple.com/app-store/review/guidelines/#software-requirements

No official API to do it. Using private API you can use following method:

-(NSString*) getMyNumber {
    NSLog(@"Open CoreTelephony");
    void *lib = dlopen("/Symbols/System/Library/Framework/CoreTelephony.framework/CoreTelephony",RTLD_LAZY);
    NSLog(@"Get CTSettingCopyMyPhoneNumber from CoreTelephony");
    NSString* (*pCTSettingCopyMyPhoneNumber)() = dlsym(lib, "CTSettingCopyMyPhoneNumber");
    NSLog(@"Get CTSettingCopyMyPhoneNumber from CoreTelephony");

    if (pCTSettingCopyMyPhoneNumber == nil) {
        NSLog(@"pCTSettingCopyMyPhoneNumber is nil");
        return nil;
    }
    NSString* ownPhoneNumber = pCTSettingCopyMyPhoneNumber();
    dlclose(lib);
    return ownPhoneNumber;
}

It works on iOS 6 without JB and special signing.

As mentioned creker on iOS 7 with JB you need to use entitlements to make it working.

How to do it with entitlements you can find here: iOS 7: How to get own number via private API?

To get you phone number you can read a plist file. It will not work on non-jailbroken iDevices:

NSString *commcenter = @"/private/var/wireless/Library/Preferences/com.apple.commcenter.plist";
    NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:commcenter];
    NSString *PhoneNumber = [dict valueForKey:@"PhoneNumber"];
    NSLog([NSString stringWithFormat:@"Phone number: %@",PhoneNumber]);

I don't know if Apple allow this but it works on iPhones.

No, there's no legal and reliable way to do this.

If you find a way, it will be disabled in the future, as it has happened with every method before.

As you probably all ready know if you use the following line of code, your app will be rejected by Apple

NSString *num = [[NSUserDefaults standardUserDefaults] stringForKey:@"SBFormattedPhoneNumber"];

here is a reference

you can use the following information instead

NSString *phoneName = [[UIDevice currentDevice] name];

NSString *phoneUniqueIdentifier = [[UIDevice currentDevice] uniqueIdentifier];

and so on

@property(nonatomic,readonly,retain) NSString    *name;              // e.g. "My iPhone"
@property(nonatomic,readonly,retain) NSString    *model;             // e.g. @"iPhone", @"iPod Touch"
@property(nonatomic,readonly,retain) NSString    *localizedModel;    // localized version of model
@property(nonatomic,readonly,retain) NSString    *systemName;        // e.g. @"iPhone OS"
@property(nonatomic,readonly,retain) NSString    *systemVersion;     // e.g. @"2.0"
@property(nonatomic,readonly) UIDeviceOrientation orientation;       // return current device orientation
@property(nonatomic,readonly,retain) NSString    *uniqueIdentifier;  // a string unique to each device based on various hardware info.

Hope this helps!

        NSLog(@"pCTSettingCopyMyPhoneNumber is nil");

You cannot use iOS APIs alone to capture the phone number (even in a private app with private APIs), as all known methods of doing this have been patched and blocked as of iOS 11. Even if a new exploit is found, Apple has made clear that they will reject any apps from the app store for using private APIs to do this. See @Dylan's answer for details.

However, there is a legal way to capture the phone number without any user data entry. This is similar to what Snapchat does, but easier, as it does not require the user to type in their own phone number.

The idea is to have the app programmatically send a SMS message to a server with the app’s unique installation code. The app can then query the same server to see if it has recently received a SMS message from a device with this unique app installation code. If it has, it can read the phone number that sent it. Here’s a demo video showing the process. As you can see, it works like a charm!

This is not super easy to set up, but it be configured in a few hours at no charge on a free AWS tier with the sample code provided in the tutorial here.
