Ensure that you’ve entered the correct phone number on the website or app, and ask to be sent the verification code again. If you don’t receive it for a few minutes, read on for five effective fixes.

Top 5 Fixes to Receive Verification Code Texts on iPhone

If the above steps didn’t bring any success, don’t worry. Applying the following five fixes to your iPhone will surely do the trick.

Fix #1: Disable ‘Filter Unknown Senders’

Open Settings and go to Messages. Scroll down and toggle off Filter Unknown Senders. You can reactivate it later if you want.

In addition, toggle on Send as SMS. Plus, toggle iMessage off and back on. If you’re using more than one SIM card in your iPhone, go to Mobile Data or Cellular and ensure that the number you want to use is activated.

Fix #2: Check Blocked Contacts

You may have blocked the number that is sending you the verification code texts. To check this, open Settings and go to Messages. Scroll down to SMS/MMS and tap on Blocked Contacts.

What if you’ve added any 5-digit verification numbers to your blocked contacts list? Tap on Edit at the top-right corner of the screen and select the ‘’ beside it. Confirm that you want to unblock it and tap on Done. You can also find the Blocked Contacts list on the Phone page!

Fix #3: Optimize Cellular Signal

Poor cellular reception might also be the cause for not receiving your verification code texts on your iPhone. Just check the bars at the top-right corner of your iPhone screen.

To improve reception, you can temporarily place your iPhone near a window or go outdoors. Once you get three bars, check if you can receive verification code texts.

Fix #4: Disable Focus

Focus silences calls and messages on your iPhone to minimize distractions. If it’s enabled currently, it could be the reason behind not receiving verification code texts. To disable it, open Control Center and tap on the Focus icon.

This will open all the Focus options; tap on the one that is enabled to disable it.

Fix #5: Reset Network Settings (Optional)

If you want to ensure that there aren’t any software errors behind not receiving verification code texts, you can reset your iPhone’s network settings. Open Settings, go to General, scroll down to Transfer or Reset iPhone, and select Reset Network Settings.

Keep in mind doing this will reset cellular settings, along with VPN, APN, and WiFi passwords.

Still Not Receiving Verification Code Texts?

If you tried the above fixes but still aren’t receiving verification code texts on your iPhone, the website or app sending you the texts may have an issue in their system. Wait a few minutes and try again.

If it still doesn’t work, contact your carrier. Once you get in touch with them, ensure that your account is active, there aren’t any network outages in your locality, and that you have a sufficient data plan for your needs. For further guidance, contact Apple Support.


Here are two common questions about the ‘iPhone won’t receive verification code texts’ issue.

How to Automatically Fill In Verification Code Texts on iPhone?

What if You Get a ‘Not Delivered’ Warning When You Send a Text Message?

If you cannot message someone on your iPhone, open Settings and go to Messages. Ensure iMessage and Send as SMS are toggled on. Check out this Support page for further guidance.


To summarize, disable Filter Unknown Senders, check Blocked Contacts, optimize cellular signal, and disable Focus on your iPhone. Implementing these fixes will hopefully enable you to receive verification code texts. If not, contact your carrier or Apple Support.
