TL;DR
Ask Siri "Whose iPhone is this?" — even on a locked device. It shows the owner's contact info, making it easy to return. Here's how to set it up for your own iPhone too.
Season: All year
 ## How to find the owner 1. **Activate Siri** — hold the side button or say "Hey Siri" (works without unlocking). 2. **Ask:** "Whose iPhone is this?" 3. Siri displays the **owner's contact information** (if configured). 4. Contact the owner — done. ## Set it up for your own iPhone 1. Open **Settings** → **Siri & Search** → **My Information**. 2. Select **your own contact** from the Contacts app. 3. Make sure it includes an **alternative phone number** or email (not the iPhone's own number — that phone is the one that's lost). 4. Tip: Add your partner's number or a landline. ## Why this works Siri can show certain information **without unlocking** — including your "My Information" card. Apple designed this intentionally so finders can reach you. Your sensitive data (photos, messages, apps) stays locked. ## Good to know - **Requirement:** Siri must be enabled and "My Information" must point to your contact. - **Bonus:** Also enable **Find My** — it lets you display a message on the lock screen and track the device. - **Privacy:** You control what's in your contact card. Less is more — one phone number is enough. - Works on all iPhones with Siri (virtually every current model).
