Free Temporary Phone Numbers
At NonVoIPZone, we believe that privacy is a human right. That is why we offer temporary non-VoIP UK numbers for free.
Use our free UK phone numbers to receive SMS verification codes and get free phone verifications for services that accept United Kingdom (+44) mobiles.
All of our numbers on this page are from United Kingdom (UK) mobile carriers. That means they are non-VoIP and work with many online services that reject cheap VoIP lines.
We update our free non-VoIP UK numbers regularly, so check back often for a new free number.
Our free numbers can be used by anyone.
NonVoIPZone’s free UK mobile numbers are shared publicly. SMS received on our free numbers are shown below. That means someone else could have already taken your favourite service, or they may take it after you.
If you need exclusive and private non-VoIP numbers, NonVoIPZone has thousands of private USA and UK lines for SMS OTP. Buy a 20-minute private verification to protect your personal information — the code stays in your dashboard only, from $0.25.
Our free numbers are refreshed periodically, so a number you used in the past might not stay available. If you think you will need the same kind of code again later, start a new 20-minute private OTP number. We do not offer long-term rentals.

Frequently asked questions
What is NonVoIPZone?
NonVoIPZone is a phone verification platform for real non-VoIP SMS OTPs. This page lists shared free UK numbers. Paid numbers are private 20-minute verifications in your dashboard, from $0.25.
Are these temporary numbers non-VoIP?
Yes. These UK numbers are issued by mobile carriers (not VoIP). We only use non-VoIP inventory across private verifications and this free shared page.
What is the difference between VoIP and non-VoIP?
VoIP numbers are cheap internet lines that many apps reject. Non-VoIP numbers use real SIMs and behave like a normal mobile number, so they are accepted by far more services.
How many phone numbers do you have?
We keep thousands of USA and UK numbers for paid 20-minute private verifications. A smaller pool of UK numbers is published here for free and is refreshed regularly.
What is the difference between free and private numbers?
Free UK numbers on this page are public and shared. Anyone can see the SMS. Private numbers are exclusive to your account for a 20-minute OTP session, from $0.25, and the code appears only in your dashboard. We do not offer long-term rentals.
Can I send SMS with these free numbers?
No. Free numbers can only receive SMS. Sending is not available on the public page.
How long does it take to receive SMS on free numbers?
Incoming messages are pushed to this page as soon as the carrier delivers them. Click Messages on a number to open its inbox on this same page. We show the latest 25 SMS and refresh about every 30 seconds.
Can these numbers be used worldwide?
Anyone can use them, but they are UK (+44) mobiles. They only work with services that accept United Kingdom phone numbers.
Where are these numbers from?
They come from major UK mobile carriers such as Three, EE, O2, and Vodafone. Each card shows the carrier for that line.
