Locating the device identification number is a common need when managing iOS devices, especially for developers, enterprise administrators, or users seeking support. This unique string of characters serves as a permanent identifier for the hardware, distinct from the phone number or Apple ID, and is essential for tasks such as enterprise app distribution, device enrollment in mobile management systems, or verifying warranty status. Finding this value is a straightforward process that integrates directly into the operating system, requiring no third-party tools or complex procedures.
Understanding the Identifier
The alphanumeric sequence assigned to every unit is officially known as the Unique Device Identifier. It is typically formatted as a 40-character hexadecimal string, combining numbers 0-9 and letters A-F. This code is generated during the manufacturing process and remains fixed, unlike software versions that update over time. Because of its static nature, it provides a reliable reference for technical support, compliance tracking, and linking device-specific information in databases or logs.
Accessing Through Settings
The most direct method involves navigating the built-in configuration menu. Users can retrieve the identifier without connecting to a computer or installing additional software. The path follows the standard hierarchy of iOS system preferences, moving from the main menu into the privacy and security subsections where hardware details are housed.
Step-by-Step Guide
Open the Settings app on the home screen.
Tap General and scroll to the bottom of the list.
Select About to view the detailed system information.
Locate the row labeled Identifier or Serial Number ; the actual code will appear directly beneath it.
Using the Configuration Utility
For users who prefer a visual interface on a desktop, the companion application provides a clear display of all connected devices. This tool is particularly useful for managing multiple units simultaneously, offering a consolidated view of identifiers, versions, and capacity without navigating through individual menus on each phone.
Desktop Retrieval Process
Once the device summary loads, the specific string is displayed prominently, often labeled as Serial Number or Hardware UUID , depending on the version of the software being used.
Via System Interface
Another approach leverages the native sharing functionality to copy the identifier to the clipboard. This bypasses the need to manually transcribe the long string of characters, reducing the risk of typos. It integrates smoothly with standard iOS features, ensuring the process remains efficient and user-friendly.
Copy-Paste Method
Navigate to Settings > General > About .
Tap and hold the Identifier field until the copy option appears.
Select Copy and paste the code into an email or document as needed.
