Question details

The user needs to change the iCloud verification method on a second-hand phone to prevent security codes from being sent to the previous owner's phone number.

Product: iCloud
Device & OS: not provided
Scenario: Setting up a newly purchased second-hand phone and attempting to add an account or passwords.
Observed behavior: iCloud or Apple account authentication codes are automatically sent to the previous owner's trusted phone number, preventing the new owner from logging in.

Before you start

Ensure that you have an official receipt or proof of purchase for the second-hand phone, as Apple Support will require this documentation to verify ownership and remove previous account bindings.

Solution 1Recommended

Contact Apple Support to Reset Account Verification

Use Apple's official support channels to request a reset of the account's verification method when you do not have access to the previous owner's trusted phone number.

Because Apple enforces strict security measures, a trusted phone number cannot be bypassed or replaced directly from the device without authentication. The official Account Recovery process or direct intervention by Apple Support is required to remove the old trusted number and assign a new one.

Visit the Apple Support Website

Go to the official Apple Support page on a browser and navigate to the Apple ID or iCloud account recovery section.

Initiate Account Recovery

Select the option indicating that you cannot access your trusted phone number or device, and begin the Account Recovery process.

Provide Proof of Ownership

Follow the prompts to submit your proof of purchase and identity to Apple so they can officially remove the Activation Lock and reset the verification method.

Account Recovery Timeframe: The Apple Account Recovery process is designed to protect user data and may take several days to complete before the verification method is updated.

Solution 2

Ask the Previous Owner to Remotely Remove the Device

If you are still in contact with the seller, they can remotely remove the device from their iCloud account, clearing the old verification requirements.

Frequently Asked Questions

Can I bypass the iCloud verification code on a used phone?

No, Apple's security infrastructure requires verification codes to be sent to the trusted number on file. You cannot bypass this without either having the previous owner remove the device from their account or going through Apple's official Account Recovery process.

What happens if the previous owner refuses to remove the Activation Lock?

If the previous owner does not remove the Activation Lock, the phone will remain tied to their Apple ID. The only way to make the phone usable is to contact Apple Support directly and provide a valid original proof of purchase to force the removal of the lock.

How do I know if a used phone has an Activation Lock before buying?

Before purchasing a used phone, always ask the seller to erase the device in front of you. When the phone reboots to the 'Hello' screen, proceed through the initial setup. If it asks for the previous owner's Apple ID and password, the Activation Lock is still active.
