To manage a Mist Access Point (AP) in the Mist cloud, it must first be "claimed" or added to an organization's inventory. There are two primary methods for this. The first is using a Claim Code, which is typically provided via email after a purchase and can be used to claim all APs associated with that specific order in a single operation. The second method is using the unique Activation Code, which is found on a sticker on the back of each individual AP. This code can be entered manually or scanned via the Mist AI mobile app's QR code scanner to claim a single device.

C. Use the serial number.

The serial number is a device identifier but is not the primary credential used in the Mist dashboard's "Claim APs" workflow.

D. Use the universal product code.

A Universal Product Code (UPC) is a generic barcode for retail products and is not used for unique network device onboarding or activation.

1. Juniper Mist Documentation, "Onboard an AP to the Mist Cloud." This document explicitly states the two methods: "You can claim an AP by using the claim code that you received in an e-mail from Mist, or by entering the activation code that is printed on the back of the AP."

3. Juniper Mist Access Point Quick Start Guide (for various models, e.g., AP43). These guides instruct users on the initial setup, stating under "Step 2: Add the AP to Your Organization": "Add the AP to your organization by using the claim code from your purchase order or the activation code from the label on the AP."
