How do I mark my iPhone as Found after being marked Lost?

Hello chm316,

Thanks for using the Apple Support Communities. It's great that your missing iPhone was returned to you! To disable Lost Mode follow the steps here:

"Turn off Lost Mode on an iPhone, iPad, iPod touch, or Apple Watch

When you find your lost device, do either of the following to turn off Lost Mode:

• Enter your passcode on the device.
• In Find My iPhone on iCloud.com, click All Devices, then select the device that’s in Lost Mode. Click Lost Mode, click Stop Lost Mode, then click Stop Lost Mode again.

Note: If you had any cards suspended when you put your device in Lost Mode (credit or debit cards for Apple Pay, or student ID cards or Express Transit cards), when you turn off Lost Mode and sign back in to iCloud, you can use them again."

Use Lost Mode in Find My iPhone on iCloud.com

Best wishes.
