What is a UDID?
A UDID (Unique Device Identifier) is a unique alphanumeric string that identifies your specific iPhone or iPad. It's required for installing Ad Hoc builds - apps distributed directly to devices without going through the App Store.
When do you need it?
Installing beta/test builds from developers
Ad Hoc distribution outside the App Store
Registering as a test device with Apple Developer
Is it safe?
Yes. The configuration profile is temporary and only used to retrieve your device info. It's automatically removed after installation. We don't store your UDID beyond the current session (10 minute cache).
Frequently Asked Questions
How does this tool find my UDID?
It uses Apple's Device Enrollment protocol. A lightweight configuration profile is installed on your device, which triggers iOS to send your device attributes (UDID, device name, etc.) to our server. The profile is temporary and auto-removed.
Why can't I install an Ad Hoc build?
Ad Hoc builds only work on devices whose UDIDs are registered in the developer's provisioning profile. If your device isn't registered, iOS will show "Unable to Install" with no further explanation. Get your UDID using this tool and share it with the developer.
Is my UDID sensitive information?
Your UDID alone can't be used to access your device or data. It's only used by Apple's provisioning system to identify which devices are authorized to install specific builds. It's safe to share with trusted developers.
Can I find my UDID without this tool?
Yes - connect your device to a Mac, open Finder (macOS Catalina+) or iTunes, select your device, and click the serial number to reveal the UDID. This web tool is a faster alternative when you don't have a Mac handy.
