How do I receive a verification code on my iPhone?

Verification codes are not sent by email as another reply implies. I suspect that is referring to a two factor recovery email.

Verification codes are sent to trusted devices. You can get them sent to a telephone by following the instructions in this support article --> Get a verification code and sign in with two-factor authentication - Apple Support

A code is sent automatically first to your trusted devices (some other Apple computer or Apple mobile device signed in with your account). If you have a trusted device running iOS11 (or iPadOS) and later, macOS 10.13 (High Sierra) and later, or watchOS 4 and later, the verification code is displayed automatically on your trusted devices.

If you don’t have a trusted device handy, you can choose to have a verification code sent to your trusted phone number as a text message or phone call.

1. Select “Didn’t Get a Code?” or “Can’t get to your devices?” on the verification code screen.

2. Choose a telephone number for where to receive a code.

3. You'll get a text message or phone call from Apple with your verification code. This text message might include an additional domain validation line. This line includes the @ symbol, the website name, and your code (for example: @icloud.com #123456 %apple.com).

4. Enter the code on your other device to complete sign in.

If you did not get a code on your telephone:

- Is your phone number listed at Settings > [name on top] > Sign in & Security > Two Factor Authentication?

- Are you able to receive other SMS messages (green)?

- If you see. “Verification codes cannot be sent to this phone number at this time. Please try again later,”:

1) Wait a few hours and try again. Maybe it really does mean not at this particular time.

2) Use this link to check the status of Apple’s various services and servers —>

3) Disable entirely any VPN you are using.

4) Try clicking on, “Cannot use this number?”

Q: Suddenly not getting texts for two factor authentication on iPhone

A: Reset network settings:

Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings

If the phone used as a trusted device is not working, try moving the SIM or eSIM to a different phone so you can get a code there.

It is a good idea to have more than one trusted number.

If you had set up a recovery contact, read Get a recovery code for a friend or family member as their Apple Account recovery contact - Apple Support

If you can’t sign in, reset your password, or receive verification codes, you can request account recovery to regain access to your account [ What to expect during account recovery - Apple Support ]. Account recovery might take a few days or longer, depending on the specific account information you can provide to verify your identity.

Here are links to posts by Community contributors which provide additional detail about the account recovery process and what to do if you do not receive a text or call: Activation Lockout Issues - Apple Community and How can I reset my Apple Account password? - Apple Community and How to delete Apple ID when you can't log… - Apple Community This thread outlines the multi-step process and final recovery —> My Apple ID is locked, how do I fix it? - Apple Community , and this one about things you should and should not do while waiting —> How can I recover my Apple ID after multi… - Apple Community This is a very long user contributed document about account recovery —> https://discussions.apple.com/docs/DOC-250009681

Welcome and thank you for reaching out. 🤗

According to Apple:

Not sure where your verification or reset email was sent? You can check all of the email addresses associated with your Apple Account or resend the email.

Search for the email:

The email is sent from “Apple”, so you can search for it in your email account. If it isn’t in your inbox, check your folders.

If a spam filter or email rule moved the email, it might be in the Spam, Junk, Trash, Deleted Items or Archive folder. You might also have to change your email address settings to allow messages from email.apple.com.

Make sure you’re checking the correct email account:

If you’re looking for a password reset email, check each email address associated with your Apple Account.

If you’re looking for a verification email, you can sign in to your Apple Account and review all the email addresses you have on file, including the one that you’re trying to verify.

If the email address is spelled incorrectly, you can update it and send another verification email.

Resend the email:

To resend a password reset email, repeat the steps to reset your password and a new email will be sent to your Apple Account primary email address.

To resend the verification email, sign in to the Apple Account on the web. Click Resend next to the email address that you want to verify and you’ll receive another email at that address.

Make sure that you’re getting email:

If you’re not getting any email, you might need to contact your email service provider for help. Learn what to do if you can’t send or receive email on your Mac or if iCloud mail isn’t working.

If you need more help, contact Apple Support directly.

Good Luck! 👋🏼😉
