Unable to link Phone number to Apple ID on my MacBook Air with "Verification codes can’t be sent to this phone number at this time" error

Hi saer98,

welcome to the Apple (user-to-user) Community!

Re: "Verification codes can’t be sent to this phone number at this time. Please try again later".

Could that phone number be already in use with another Apple ID ?

Else:

If you haven't already: Wondering if updating your MacOS version to the newest version may help:

Eg: What's new in the updates for macOS Sonoma - Apple Support

says macOS Sonoma 14.6.1 is the latest version:

"This update includes important bug fixes and addresses an issue that prevents enabling or disabling Advanced Data Protection"

NB: It is always wise to back-up the data on your Mac before updating

Restarting your Mac (Apple Menu > Restart) is another option that often restores order when something is not working as expected ... (eg: deletes temporary files, re-establishes connections, may update recent setting changes, and more.)

Also: There are a few ways you can get a verification code. You can use the code displayed on your trusted device, get a text or phone call, or generate a code from your trusted device.

Get a verification code and sign in with two-factor authentication - Apple Support

All the best :-)

You may want to check these pages to see if there are any outages. 

Apple - Support - System Status

And

System Status - Apple Developer

(All with a green dot are ok.)

If you haven't already: You might try iCloud.com

Eg: see if you can access your photos, files and more from any web browser

I too started having this problem yesterday. I have had my only cell phone number tied to three accounts (personal account, side business Apple Developer account, and an account tied to some Apple Publishing). I tried to upload a book last night, and Apple said: "Verification codes can’t be sent to this phone number at this time. Please try again later." It also won't call me to verify. It looks to me like the service is just down, as this has worked for the past several years.

I can't use an alternate option, because I never log into anything but the Apple Publishing site with this third account. There are no trusted devices, and I can't log into iCloud anywhere because it won't verify my phone number.

All the dots are green, but Apple support chat confirmed there is an outage with dual factor authentication.

Thank you kindly for checking, for replying, and for letting us know !
