Udid.io gives you one tap to find the UDID of your iPhone, iPad or iPod directly using mobile Safari without need in iTunes or desktop/MacBook computer. UDID of your device is needed to iOS developers to be available to install early versions of mobile applications onto your device to debug and test such apps.
We don't store any of your private data on our servers. All data transferring to your browser has been ciphered using 256-bit AES to prevent hijacking. Don't tell your UDID of iPhone, IMEI or Serial Number to any non-trusted third party persons to be kept from fraud.
You may use iTunes instead to find UDID. But we recommend to use our simple one-tap service to find UDID of your device, because it's fast, easy, secure and doesn't require desktop with iTunes installed. We hope you're tester or mobile apps developer or kind of them. If you don't really understand the purpose of the service, please take a look at about page where our service explained in details
UDID.io uses Apple Mobile Device Management concepts to provide you information about your device. Profile you install tells your iPhone, iPad or iPod to send encrypted data (UDID, IMEI, Serial No, & etc) to your browser. This profile is temporary and exists on your device only for a few moments to send encrypted data. After this profile removed from your iOS device. We do not store or reuse any of your device information.
To check if there is any profiles installed on your device you check on your iOS device Settings->General->Profiles. If there is no such section then there is no installed profiles on your device.
Apple allows to get UDID, IMEI, Serial No., Product Name and iOS Version. UDID.io provides all this information to you and doesn't get access to anything of this.
You can use your UDID to allow iOS-developers make apps for you and to get access to beta versions of iOS (you can find information about it in Google)
