If you’re looking to create a ChatGPT account without linking your personal phone number, using real SIM-based disposable numbers is a reliable option. These numbers, unlike VoIP services, meet OpenAI’s strict verification requirements and have a nearly 100% success rate. Services like MobileSMS.io provide temporary SIM-based numbers specifically for this purpose, ensuring privacy and security during the signup process.
Key Points:
- OpenAI blocks most VoIP numbers due to security concerns.
- Real SIM-based numbers work because they operate on traditional cellular networks.
- Services like MobileSMS.io offer one-time use numbers starting at $3.50, with options for extended rentals.
- The process is simple: rent a number, receive the verification code, and complete your account setup.
Why use disposable numbers?
- Protect your personal number from spam or data breaches.
- Avoid linking your real phone to your OpenAI account.
- Ensure smooth verification with minimal hassle.
Why VoIP Numbers Get Rejected
OpenAI takes security seriously, especially when it comes to preventing fraudulent account creation. That’s why they have strict rules about the types of phone numbers allowed during ChatGPT registration. If you try using a VoIP number, you might encounter a message like this:
"It looks like this is a virtual phone number (also known as VoIP). Please provide a valid, non-virtual phone number to continue."
This isn’t just a suggestion – it’s a firm requirement backed by advanced detection systems. OpenAI’s verification tools are designed to spot and block VoIP numbers, including those from wholesale providers. But why are these numbers flagged?
VoIP numbers are easy to obtain and just as easy to discard, making them unreliable for secure verification. On the other hand, SIM-based numbers from traditional carriers are tied to physical devices and require stricter identity checks. This connection to a physical device aligns with rigorous security standards, such as those outlined in the NIST Special Publication 800-63B guidelines for out-of-band authentication.
Here’s a stark comparison: VoIP numbers see an acceptance rate of about 40%, while SIM-based numbers have an acceptance rate of over 99%. The difference underscores why OpenAI prioritizes the latter for account verification.
What Are Real SIM-Based Disposable Numbers
If you’re looking to bypass ChatGPT’s phone verification without using your personal number, real SIM-based disposable numbers offer a secure and practical solution. Unlike VoIP numbers, which are often rejected, these numbers are tied to physical SIM cards and operate on traditional cellular networks. Since they connect through cellular towers, they provide a level of authenticity that VoIP numbers simply can’t match. This makes them not only more reliable but also a safer option for protecting your privacy.
Privacy is the biggest perk. Instead of handing over your personal phone number – which could end up in marketing databases, sold to third parties, or targeted by spam – you use a temporary number that gets the job done and vanishes. By keeping your real number private, you reduce the risk of data breaches or annoying sales calls.
Another major advantage is their reliability. While VoIP numbers have a low acceptance rate of around 40% on major platforms, real SIM-based numbers boast an impressive 99.7% acceptance rate. This means you’re almost guaranteed to get verified on your first try, saving you time and frustration.
These numbers are perfect for one-time uses, like creating a ChatGPT account. You don’t need a permanent number – just one that works flawlessly for the verification step. Once you’ve received your SMS code and set up your account, the temporary nature of the number adds an extra layer of security, as it can’t be reused or compromised later.
The process is straightforward: rent a real SIM-based number, use it to receive the verification code, and finish your account setup. Since these numbers are indistinguishable from regular mobile numbers to OpenAI’s systems, verification happens seamlessly, without triggering the dreaded "virtual phone number" rejection.
How to Bypass ChatGPT Phone Verification Using MobileSMS.io
If you’re looking for a way to bypass ChatGPT’s phone verification, MobileSMS.io offers a simple solution using real SIM-based numbers. Here’s a step-by-step guide to help you get started.
Setting Up MobileSMS.io and Getting a Number
First, head over to MobileSMS.io and sign up with your email and password. Once you’ve registered, you’ll gain access to a dashboard where you can manage your credits and numbers.
To get started, you’ll need to add credits. Click on "Top-Up" in the dashboard and make a deposit. The minimum amount is $5.00, and your credits will remain valid for 12 months. Add enough credits based on your needs.
For ChatGPT verification, you have two main options:
- One-Time Verification Number: Ideal if you only need to create one OpenAI account, starting at $3.50.
- Single Service Number: Perfect for managing multiple accounts or for ongoing use, priced at $15 for 7 days or $30 for 30 days.
Once you’ve added credits, browse through the available numbers. MobileSMS.io offers numbers from over 100 countries, but U.S. numbers are particularly effective for OpenAI verification. Select "OpenAI" or "ChatGPT" from the service list, choose the United States, and purchase a number. The system will assign you a real SIM-based number ready to receive SMS messages.
Now you’re set to begin the OpenAI account registration process.
Creating Your OpenAI Account
With your MobileSMS.io number ready, go to chat.openai.com and click "Sign up" to start creating your account. You can register using your email address or sign in through Google, Microsoft, or Apple.
Fill in your basic details, such as your name and email address. When you reach the phone verification step, copy the number from your MobileSMS.io dashboard and paste it into the phone number field on OpenAI’s registration form. Be sure to include the correct country code to avoid errors.
Click "Send code" or "Verify" to initiate OpenAI’s SMS verification process. Since the number is SIM-based, it meets OpenAI’s requirements seamlessly.
Getting and Using the Verification Code
Next, check your MobileSMS.io dashboard for the verification code. The SMS usually arrives within 30–60 seconds and will be displayed in real time. For example, the message might say: "Your OpenAI verification code is: 123456."
Copy the 6-digit code from the dashboard and paste it into the verification field on OpenAI’s site. Click "Verify" to complete the process. This ensures your personal number stays private while using MobileSMS.io‘s secure system.
Once OpenAI confirms the code, you can finish setting up your account by creating a password and agreeing to the terms of service. Your account is now active, and since OpenAI only requires phone verification during signup, you won’t need the temporary number again for that account.

Privacy and Security Benefits
When you use MobileSMS.io for ChatGPT verification, you’re taking a big step toward protecting your privacy. By keeping your real phone number hidden, you reduce the risk of it being linked to your identity, giving you greater control over your personal information.
One major bonus? Spam prevention. By using a disposable number, you can shield your primary phone from annoying promotional messages, robocalls, and other unwanted communications. Once your personal number lands in a company’s database, it could be shared with marketers, sold to data brokers, or even exposed in a data breach. MobileSMS.io helps you avoid all of that.
Disposable numbers also lower the risk of data breaches and SIM-swapping attacks. These temporary numbers act as a barrier, keeping your personal details separate from your account activity and stopping cross-account data connections.
What makes MobileSMS.io stand out is its use of real SIM-based numbers. Unlike internet-based phone services, these numbers operate on carrier networks, offering a higher level of security and reliable message delivery through trusted telecommunications systems.
And here’s another layer of protection: once you’ve verified your account, the temporary number essentially vanishes from the equation. This means no lingering privacy risks, even if you’re managing multiple accounts. It’s a simple, secure solution for safeguarding your online presence.

FAQs
Why does OpenAI need a phone number for ChatGPT account setup, and why aren’t VoIP numbers allowed?
During the ChatGPT account setup, OpenAI asks for a phone number to boost security and help prevent fraudulent activities. Tying accounts to real phone numbers makes it easier to confirm users’ identities and reduces the chances of misuse, like creating multiple fake accounts.
VoIP numbers are generally not accepted because they are often associated with automated systems or mass account creation. Unlike standard mobile numbers, they don’t offer the same level of verification reliability. Using a real, SIM-based phone number ensures a smoother verification process and helps maintain the platform’s integrity.
Why is using a real SIM-based disposable number from MobileSMS.io better for protecting my privacy than my personal phone number?
Using a real SIM-based disposable number from MobileSMS.io is a smart way to protect your privacy. By keeping your personal phone number hidden, you minimize the chances of unwanted calls, tracking, or exposing sensitive information.
What sets SIM-based numbers apart from virtual or VoIP options is their connection to physical SIM cards. This makes them far more secure and less prone to hacking or interception. With this extra layer of security, you can reduce risks like identity theft, spam, and other privacy threats – especially when you’re verifying accounts or signing up for online services.
What are the costs and advantages of using MobileSMS.io for verifying multiple OpenAI accounts?
If you’re managing multiple OpenAI accounts, MobileSMS.io provides a reliable and budget-friendly way to handle verifications. The service charges $0.25 per SMS, but you can save more with bulk or long-term rental options, like paying $100 for a 30-day premium number. These plans help bring down the overall cost per verification, making it a smart option for those juggling multiple accounts.
What sets MobileSMS.io apart is its use of real SIM-based numbers rather than traditional VoIP numbers. This not only boosts reliability but also adds an extra layer of privacy. With this approach, the verification process becomes smoother and more secure. For anyone looking for an efficient and scalable solution, MobileSMS.io offers a dependable way to manage multiple verifications without hassle.
