How to get iOS device MAC address programmatically

5 Solutions Collect From Internet About “How to get iOS device MAC address programmatically”

Now iOS 7 devices – are always returning a MAC address of 02:00:00:00:00:00.

So better use [UIDevice identifierForVendor]

so better to call this method to get app specific unique key

Category will more suitable

#import "UIDevice+Identifier.h"

- (NSString *) identifierForVendor1
    if ([[UIDevice currentDevice] respondsToSelector:@selector(identifierForVendor)]) {
        return [[[UIDevice currentDevice] identifierForVendor] UUIDString];
    return @"";

Now call above method to get unique address

NSString *like_UDID=[NSString stringWithFormat:@"%@",
                [[UIDevice currentDevice] identifierForVendor1]];


You can get the MAC Adress using the following function:

+(NSString *)getMacAddress
    int                 mgmtInfoBase[6];
    char                *msgBuffer = NULL;
    NSString            *errorFlag = NULL;
    size_t              length;

    // Setup the management Information Base (mib)
    mgmtInfoBase[0] = CTL_NET;        // Request network subsystem
    mgmtInfoBase[1] = AF_ROUTE;       // Routing table info
    mgmtInfoBase[2] = 0;              
    mgmtInfoBase[3] = AF_LINK;        // Request link layer information
    mgmtInfoBase[4] = NET_RT_IFLIST;  // Request all configured interfaces

    // With all configured interfaces requested, get handle index
    if ((mgmtInfoBase[5] = if_nametoindex("en0")) == 0) 
        errorFlag = @"if_nametoindex failure";
    // Get the size of the data available (store in len)
    else if (sysctl(mgmtInfoBase, 6, NULL, &length, NULL, 0) < 0) 
        errorFlag = @"sysctl mgmtInfoBase failure";
    // Alloc memory based on above call
    else if ((msgBuffer = malloc(length)) == NULL)
        errorFlag = @"buffer allocation failure";
    // Get system information, store in buffer
    else if (sysctl(mgmtInfoBase, 6, msgBuffer, &length, NULL, 0) < 0)
        errorFlag = @"sysctl msgBuffer failure";
        // Map msgbuffer to interface message structure
        struct if_msghdr *interfaceMsgStruct = (struct if_msghdr *) msgBuffer;

        // Map to link-level socket structure
        struct sockaddr_dl *socketStruct = (struct sockaddr_dl *) (interfaceMsgStruct + 1);

        // Copy link layer address data in socket structure to an array
        unsigned char macAddress[6];
        memcpy(&macAddress, socketStruct->sdl_data + socketStruct->sdl_nlen, 6);

        // Read from char array into a string object, into traditional Mac address format
        NSString *macAddressString = [NSString stringWithFormat:@"%02X:%02X:%02X:%02X:%02X:%02X",
                                      macAddress[0], macAddress[1], macAddress[2], macAddress[3], macAddress[4], macAddress[5]];
        if(IsDEBUG) NSLog(@"Mac Address: %@", macAddressString);

        // Release the buffer memory

        return macAddressString;

    // Error...
    if(IsDEBUG) NSLog(@"Error: %@", errorFlag);

    return errorFlag;

But as he said #Randomclik, mac address is unavailable from ios 7 and up.

form apple:

In iOS 7 and later, if you ask for the MAC address of an iOS device, the system returns the value 02:00:00:00:00:00. If you need to identify the device, use the identifierForVendor property of UIDevice instead. (Apps that need an identifier for their own advertising purposes should consider using the advertisingIdentifier property of ASIdentifierManager instead.)


Conversation about MAC Address:

How can I programmatically get the MAC address of an iphone

It seems that in iOS 7 and later get MAC addres will not work. Look at What’s new on iOS document from Apple. (Deprecated APIs section.)

everybody is good advised to use the offical ios 7 way and use [UIDevice identifierForVendor]

And also think about the migration from some older assumptions.

You can get it by combining the following two answers i guess.

First, find ip of the device by using the following:

Second, find the MAC of that address, by using the following:

I’ll be trying it out now and will let you know how it goes.
