Frequently asked questions
What is a UDID and why is it important?
A UDID (Unique Device Identifier) is a unique alphanumeric string assigned to each iOS device. It is used by developers to identify and register devices for app testing and distribution, especially in ad hoc app deployment. Knowing your device’s UDID is essential when you want to get access to apps that are not available on the App Store.
How can I get the UDID of my iPhone or iPad?
The easiest way to get your UDID is to open Median.co's UDID retrieval tool in Safari on your iPhone or iPad. Simply follow the prompts to install a temporary profile that securely displays your UDID without needing a computer. Alternatively, you can connect your iOS device to a Mac or PC with a USB cable, then open Finder on macOS Catalina or later, or iTunes on older macOS versions or Windows. In Finder, select your iPhone or iPad from the sidebar under Locations. In iTunes, click the device icon near the top-left of the window. Then click the serial number or identifier until the UDID appears, and copy it to your clipboard.
Can I find my UDID without connecting to a computer?
Yes, you can get your UDID directly on your iOS device by using Safari and visiting trusted UDID retrieval websites like Median’s UDID retrieval tool. These sites guide you through installing a temporary profile that reveals your device UDID securely without needing a computer.
Why do developers ask for my UDID?
Developers request your UDID to register your iOS device in their Apple Developer account for ad hoc app distribution. This registration allows the app to be installed and run only on devices with registered UDIDs, ensuring controlled and secure testing environments.
Is it safe to share my UDID?
Sharing your UDID is generally safe when done with trusted developers or organizations because it only identifies your device for app testing purposes. However, avoid sharing your UDID publicly or with untrusted sources to prevent unauthorized access or misuse.
