Creating an online account often means handing over more personal information than you would prefer. For privacy-conscious users, one question comes up frequently: How can you create a ChatGPT account without using your personal phone number?
The answer depends on the signup flow you encounter.
OpenAI's current help documentation says phone verification is not required for new ChatGPT account creation or normal ChatGPT usage. Phone verification is instead associated with certain OpenAI API account activities, including generating an initial API key.
That means many people searching for ChatGPT without phone number can simply use the standard ChatGPT signup process. However, if a phone verification prompt appears for a particular workflow and an alternative number is permitted, an online SMS verification service such as SMS COOL can be a practical option for receiving a verification message without immediately exposing your personal number.
Yes, for normal ChatGPT account creation, you may be able to create an account without providing a phone number.
The important distinction is between avoiding your personal number and bypassing a required verification process.
If the regular ChatGPT signup flow does not request a phone number, there is no need to add one. You should simply complete the registration using the available sign-in method.
On the other hand, if a particular OpenAI workflow explicitly requires phone verification, you should not attempt to circumvent that security requirement. Instead, if an alternative number is accepted for that legitimate verification step, you can consider an appropriate virtual or temporary number.
This is where online SMS verification can become useful.
OpenAI's requirements can also differ between ChatGPT and the OpenAI API, so always follow the instructions displayed by the official service.
There are several perfectly legitimate reasons someone may prefer not to use their everyday number for every online account.
Your phone number is personal contact information. Some users simply prefer keeping it separate from online services whenever possible.
A separate verification number can help keep personal communications apart from registration-related SMS messages.
Not every online service needs to be connected to your primary mobile number. When an alternative verification method is legitimately accepted, it can provide greater separation.
People who regularly register for software, websites, testing platforms, or other digital services may prefer having a dedicated verification option rather than using their personal SIM repeatedly.
The goal should not be to defeat security controls. Instead, it is about choosing an appropriate verification method for a legitimate account-registration process.
SMS COOL is an online SMS verification service that provides virtual and temporary phone numbers for receiving SMS messages and verification codes.
The basic concept is straightforward: rather than using your personal mobile number for every supported verification task, you can obtain a suitable virtual number and receive the incoming SMS through an online dashboard.
SMS COOL describes its service as providing temporary numbers, longer-term number rentals, and SMS receiving options for online verification. Its platform also lets users select a service and receive the corresponding OTP in the dashboard.
This makes SMS COOL particularly relevant to people searching for a temporary phone number for verification, a virtual number for SMS verification, or a convenient way to receive verification SMS online.
However, SMS COOL does not guarantee that every number will be accepted by every third-party platform. Its terms specifically state that successful registration with third-party services is not guaranteed.
For most users, start with the official ChatGPT signup process rather than assuming phone verification is required.
If your particular registration or related OpenAI workflow requests phone verification and allows an alternative number, the general process is:
The key point is that SMS COOL is not a way to bypass OpenAI's security systems. It is simply a tool for receiving SMS when a legitimate online verification process accepts the number being used.
When a website requires SMS verification, the process normally involves three basic actions: provide a number, receive a verification message, and enter the code.
SMS COOL can simplify the receiving part of that process.
You select an available number, use it for a supported verification task, and monitor the incoming message through the SMS COOL platform. If the SMS arrives, the displayed verification code can then be entered into the service requesting it.
This can be useful when you want to:
The important limitation is compatibility. A number that works for one platform may not necessarily work for another, and availability can change.
For users who need an alternative to their personal number, SMS COOL offers several practical advantages.
Before using any online phone verification service, keep a few practical considerations in mind.
Verification availability can vary. A number may be unavailable, already used, unsupported, or rejected by the target platform.
Not every number works everywhere. Websites can restrict temporary, virtual, VoIP, or other number types. Never assume that an SMS COOL number will automatically be accepted.
Follow OpenAI's requirements. If the official ChatGPT signup flow does not request a phone number, you do not need to add one. If another OpenAI workflow requires verification, follow the applicable requirements.
Keep verification codes private. An OTP or verification code should never be shared with another person.
Consider account recovery. A temporary number may not be suitable when you need long-term access to the same number. SMS COOL offers rental options, but you should still consider the recovery requirements of the specific account.
Use services legitimately. An SMS verification service should be used for lawful, authorized registration and verification purposes—not to evade platform restrictions or create abusive accounts.

Neither option is universally better. If your priority is keeping your personal number separate, SMS COOL can be an attractive option when the target service accepts the number. If you expect to need the number for future account recovery, a personal or dedicated long-term number may be more appropriate.
For normal ChatGPT account creation, OpenAI's current help guidance says phone verification is no longer required. You can therefore create a ChatGPT account without entering a personal phone number when the standard signup flow does not request one.
Yes, normal ChatGPT usage does not currently require phone verification according to OpenAI's help documentation. However, different OpenAI services and workflows can have different requirements, so follow the verification instructions shown for the specific service you are using.
If your particular OpenAI workflow requests a verification code, use the verification method offered on the official page. Where an alternative number is accepted, an online SMS verification service such as SMS COOL may provide a number capable of receiving the SMS.
SMS COOL provides virtual and temporary numbers intended for receiving SMS verification messages. Whether a particular number receives a ChatGPT-related message depends on the number, service requirements, and OpenAI's acceptance of that number type. SMS COOL itself does not guarantee successful registration with third-party platforms.
Yes. SMS COOL is specifically designed around virtual numbers and SMS receiving for online verification workflows. It can be useful when you need to receive a verification SMS without immediately using your personal phone number.
Only if the relevant ChatGPT or OpenAI workflow accepts that type of number. Temporary numbers are not universally accepted, so check the requirements before purchasing or using one.
First, check that the country and number are correct, that the target service supports the number type, and that you have waited for the message to arrive. Avoid repeatedly requesting codes in rapid succession. If the SMS still does not arrive, try an available number that is appropriate for the service or use the official support channel.
If your goal is to create a ChatGPT account without phone number, the first thing to know is that normal ChatGPT signup no longer requires phone verification according to OpenAI's current documentation. That makes the standard ChatGPT registration process the simplest option for many users.
For situations where an OpenAI or other online verification workflow does require a phone number, the issue becomes different: you may want to avoid exposing your personal number while still completing a legitimate SMS verification step.
That's where SMS COOL can be useful. Its virtual and temporary numbers provide a practical way to receive SMS verification messages online when the relevant service accepts them.
If privacy and separation are important to you, explore SMS COOL and choose a number appropriate for your verification needs. Just remember to check the target platform's requirements, keep verification codes private, and use the service only for legitimate account verification.
