How To Add UDID To Apple Developer Account?

To distribute iOS apps outside the App Store (via Ad Hoc or Development builds), you need to register each test device's UDID in your Apple Developer account.

If you don't have the UDID yet, use one of the methods below to find it, then register it with your developer account.

Find Your UDID Using Apple Music App

1. Connect your iPhone or iPad to your PC or Mac.
2. Launch the Apple Music app (or iTunes on older systems).
3. Click the device icon from the left sidebar.
4. Your device appears in the top center of the app.
5. Click the device name or serial number to reveal the UDID.
6. Your device's UDID will appear on the screen. Right-click to copy it.

Find UDID Using Xcode

1. Connect your iOS device to your Mac.
2. In Xcode, go to Window → Devices and Simulators.
3. Select your device from the list. The UDID is shown next to Identifier.

Use Finder on macOS

On macOS Catalina or later, Finder manages connected iOS devices directly:

1. Connect your iPhone or iPad to your Mac with a USB cable.
2. Open Finder and select your device under Locations in the left sidebar.
3. Click the info line below the device name (it shows the model or serial number).
4. Keep clicking — it cycles through Model, Serial Number, and UDID.
5. Right-click (or Control-click) the UDID and select Copy UDID.

Find Your UDID Using TestApp.io

If your device can't be connected to a computer, TestApp.io can read your UDID directly from the device. It installs a temporary configuration profile that reads the UDID — no computer required.

Register the UDID in Your Developer Account

Once you have the UDID, register the device in your Apple Developer account:

1. Log in to developer.apple.com → Certificates, Identifiers & Profiles → Devices
2. Click the + button to register a new device.
3. Select Register Device.
4. Enter a device name and paste the UDID.
5. Click Continue, review the information, then click Register.

Update the Provisioning Profile

Next, add the new device to your app's provisioning profile:

1. In the Apple Developer portal, click Profiles from the left sidebar.
2. Select the provisioning profile for your app.
3. Click Edit.
4. Select your app's App ID.
5. Check the newly registered device from the device list.
6. Click Generate and download the updated profile.

Rebuild the App

Finally, rebuild your app with the updated provisioning profile:

1. Import the downloaded profile into Xcode.
2. Open your project in Xcode and go to Build Settings.
3. Search for Code Sign.
4. Under your release configuration, select the newly generated provisioning profile.
5. Build the app via Product → Archive.

That's it! You can now upload the new .ipa and distribute it to your testers.
