Buying a used iPhone can save money, but only if you verify the device first. Follow this checklist before handing over payment.
Ask the seller to dial *#06# while you watch, or go to Settings → General → About → IMEI. Never rely on a photo of the IMEI — see it live on the device.
Use our free IMEI verification tool to check:
Go to Settings → [Your Name] → Find My. If "Find My iPhone" is ON and linked to another Apple ID, the seller must remove it before you buy. A device locked to another account cannot be used.
