What you should say is the date when the warranty starts. When products purchased in official website are shipped from official website, invoices and receipts will be issued, and the warranty period will start from the date of receipt, while 14 days has no reason to start from the date when you actually receive the goods. As for activation, there is no pre-activation, which is the most impossible from official website!
Pre-activation doesn't mean that your device is really activated, but its warranty is based on the official delivery date, so the activation date you inquired will be the same as the official delivery date; It's the same whether it's an education discount or not.
For the official pre-activated products purchased through third-party channels, use the "Fruit Powder Identification Service Number" in WeChat official account, and the query will show that it is activated, but the activation date will show "Please verify your purchase date". When you actually activate the product, the activation date will be automatically displayed, excluding (Air Pods, Apple Pencil).
If Air Pods and Apple Pencil are purchased by a third party, you need to go to the official to submit the purchase date or provide an invoice to contact customer service for updates, and then inquire about the activation date and other information.
Official non-pre-activated products, whether purchased in official or third-party channels, will be displayed as inactive on the "Fruit Powder Identification Service Number" on WeChat before the device is activated.
