If you're developing or testing iOS apps, your device’s UDID (Unique Device Identifier) is often required. Whether it’s for app provisioning, beta testing, or internal company usage, knowing how to find UDID on iPhone is essential. However, many users struggle to locate it, especially since Apple removed direct access through the device settings.
In this blog, we’ll show you 6 quick and easy steps to find your iPhone’s UDID safely and efficiently. Let’s dive in!
What is UDID & Why Is It Important?
UDID stands for Unique Device Identifier, a 40-character alphanumeric string assigned to every iOS device. Developers and companies often need UDID to:
Register devices for app testing.
Grant access to pre-release apps.
Personalize and manage specific device profiles.
It’s like a fingerprint for your iPhone—unique and crucial in app development and testing environments.
