Why Does Bybit Ask for Your Phone Number – and Can You Use a Virtual One?
You do not need to use a personal phone number to create every Bybit account: Bybit currently allows registration with an email address or mobile number and recommends email registration. When a phone is actually required – for mobile registration, SMS authentication or certain account features – you can consider either a one-time SMS number for a single code or a long-term virtual number if you need to retain access to the same phone.
Revosim offers both options: Bybit is listed as a dedicated SMS-activation service, while virtual-number rental is available separately for longer-term use. The important difference is not simply price: it is whether you expect to need the same number again in the future.
Bybit phone numbers at a glance
| Question | Answer |
|---|---|
| Is a phone number required to create a Bybit account? | No. You can register with email instead |
| Can you register with a phone number? | Yes |
| Does Bybit send verification codes to phones? | Yes |
| Can a virtual number be used? | Potentially, if Bybit accepts the particular number |
| Is Bybit available on Revosim? | Yes, as a dedicated one-time SMS service |
| What is best for one verification code? | One-time SMS activation |
| What if you need the same number later? | Long-term virtual number rental may be more appropriate |
| Can the same mobile number be used for several Bybit accounts? | No. Each mobile number can only be linked to one account |

Bybit specifically recommends email registration because email and Google Authentication are required for withdrawals, whereas SMS Authentication is not. Each email address and mobile number can only be linked to one account.
Why does Bybit use a phone number?
A phone number on Bybit is not just a registration field.
Users can link a mobile number to enable SMS Authentication, which gives Bybit another channel for sending security verification codes. A phone number can also become relevant when changing security settings, recovering access or using certain products.
This means there are really two different questions:
Do I need a phone number to create an account? Not necessarily.
If I link a phone number, might I need access to it again? Yes.
That distinction is important when choosing between a disposable SMS number and a long-term virtual number.
Can you register for Bybit without a phone number?
Yes.
Bybit currently lets users create an account with:
- an email address;
- a mobile number;
- Google;
- Apple on supported devices;
- Telegram in supported flows.
If you sign up by email, the registration code is sent to the email address rather than to a phone.
So if your only goal is to open a Bybit account and you do not specifically need SMS Authentication, you may not need a virtual number at all.
A virtual number becomes relevant when the flow you are using genuinely requires a mobile phone.
Two ways to use a virtual number with Bybit
Revosim has two different products for this use case.
Option 1: One-time Bybit SMS activation
Bybit is listed as a dedicated service in the Revosim SMS catalogue. You choose Bybit, select an available country, receive a temporary number and use it to receive the verification message. Revosim currently has country-specific Bybit inventory, including dedicated Bybit activation pages.
This option makes sense when:
- you need one Bybit verification code;
- the number is required for a one-off check;
- you do not need to keep the same phone afterwards;
- you understand that future access to that number is not guaranteed.
A one-time number should not be treated as a permanent account-recovery method.
Option 2: Long-term virtual number
A long-term virtual number remains available for the chosen rental period rather than disappearing after one verification.
Revosim currently offers rental plans for 30 and 365 days, with pricing starting from $6.99 for 30 days and $39.99 for 365 days for supported countries. Actual price and availability depend on the country and current inventory.
A rented number may make more sense when:
- you want to keep one phone number attached to Bybit;
- repeated SMS codes may be needed;
- you want a separate number without using your personal SIM;
- you expect to use the number for several months;
- future account changes may require access to the phone.
A rented number is not automatically guaranteed to work with Bybit simply because it can receive SMS. The platform still decides whether a particular number is accepted.
One-time SMS or long-term virtual number?
| Use case | One-time SMS activation | Long-term virtual number |
|---|---|---|
| Receive one Bybit code | ✓ | Possible |
| One-off phone verification | ✓ | ✓ |
| Keep the same number | ✗ | ✓ |
| Receive later SMS messages | ✗ | Potentially |
| Use for several months | ✗ | ✓ |
| Permanent SMS Authentication | Poor choice | More suitable |
| Recover the account later | Less convenient | Easier while rental is active |
| Avoid using a personal SIM | ✓ | ✓ |
If the task is simply “I need one Bybit code now”, one-time activation is the simpler option.
If the phone is going to become part of the account, a long-term number is the more logical choice.
For an account holding significant funds, a phone number that you can reliably control for years remains the safest approach.
How to receive a one-time Bybit SMS with Revosim
The process is straightforward.
1. Open SMS Activation
Sign in to Revosim and open the service catalogue.
2. Select Bybit
Choose Bybit directly rather than a generic SMS category. Bybit is currently available as a dedicated service in the catalogue.
3. Choose a country
Check current availability and pricing.
Do not choose a country only because the number is cheaper. Bybit asks users to select their actual country of residence during registration and may redirect users to regional sites or restrict access based on local regulations.
4. Get the virtual number
Copy the number provided in your Revosim dashboard.
5. Enter it on Bybit
Select the correct country code and enter the phone number.
Bybit instructs users to omit the leading domestic zero after selecting the international country code.
6. Request the code
If Bybit accepts the number, it will send a verification message.
7. Enter the verification code
The message will appear in Revosim if delivery succeeds. Enter the code in the Bybit form to continue.
If Bybit rejects the number before sending anything, repeatedly requesting another code will not help. The issue is with the number itself or its eligibility rather than SMS delivery.
How to use a long-term virtual number for Bybit
If you want to keep the same number:
- Open Virtual Number Rental in Revosim.
- Choose an available country.
- Select the rental period.
- Check that the number is appropriate for your intended use.
- Add it to Bybit.
- Complete the initial phone verification.
- Keep the rental active while the number remains linked to your account.
The practical advantage is continuity. The number does not disappear after the first verification, so you retain access during the rental period. Revosim currently offers both monthly and yearly rental options.
How to add a phone number to an existing Bybit account
You do not need to create a new account simply because you registered with email first.
Bybit allows users to bind a mobile number later from account security settings. The platform first verifies the existing account, then asks for the country code and new phone number, and finally sends a verification code to the phone.
Once successfully linked, the number can be used for SMS Authentication.
Why is the Bybit verification code not arriving?
Bybit now uses two possible mobile OTP channels: SMS and WhatsApp. Users select the preferred method during the first security verification. If WhatsApp OTP is successfully delivered and confirmed, WhatsApp becomes the default channel. If WhatsApp delivery fails, Bybit may automatically fall back to SMS.
That means “my Bybit SMS never arrived” may occasionally have a very simple explanation: the code was sent to WhatsApp instead.
| Problem | What to check |
|---|---|
| SMS inbox is full | Delete old messages |
| Weak network signal | Restart the phone and check reception |
| Security app blocks SMS | Review filtering or blocking apps |
| Mobile operator blocks OTP messages | Contact the operator |
| Dual-SIM issue | Try another SIM slot or device |
| Code is being sent through WhatsApp | Check WhatsApp |
| WhatsApp OTP does not arrive | Check internet connection and WhatsApp registration |
| Virtual number receives nothing | Try another compatible number |
These are based on Bybit's current troubleshooting guidance for mobile verification codes.
Why did the Bybit code arrive in WhatsApp instead of SMS?
This is now normal behaviour.
Bybit allows users to choose SMS OTP or WhatsApp OTP during the first security verification. Once WhatsApp has successfully delivered and verified the first code, it becomes the default mobile verification channel.
If the WhatsApp message cannot be delivered, Bybit says it may automatically fall back to SMS.
This matters when choosing a virtual number because a number that can receive SMS does not automatically give you control of a WhatsApp account registered to that phone.
How to change your Bybit phone number
A registered phone number can be changed from the security settings.
Bybit's current process requires verification through existing security methods before the new number is confirmed. Google Authentication must also be set up before the registered mobile number can be changed.
After changing your mobile number, Bybit applies a 24-hour security restriction to:
- crypto and fiat withdrawals;
- internal transfers;
- Bybit Card transactions;
- P2P trading;
- P2P advertising.
So changing your phone immediately before a planned withdrawal is not a good idea.
What if you no longer have access to the old number?
Losing the old SIM does not automatically mean losing your Bybit account.
Bybit has a self-service recovery process accessible from the login flow. Users who permanently lose access to a phone, email address or Google Authenticator can choose Having problems with verification and submit a request to change the unavailable security method.
Additional verification may be required to prove ownership of the account.
This is exactly why the lifespan of a virtual number matters. A one-time number may be perfectly adequate for today's SMS but inconvenient six months later if the same phone becomes part of an account-recovery flow.
Can one phone number be used for multiple Bybit accounts?
No.
Bybit states that each email address and mobile number can only be linked to one account.
This can be relevant with recycled or virtual numbers: a phone number that is new to you may already have a history with Bybit.
If the platform says the number is already registered, repeatedly requesting another verification code will not solve the issue. A different number may be required.
Do you even need to keep SMS Authentication enabled?
Not necessarily.
Bybit recommends registration using email and states that email and Google Authentication are compulsory for withdrawals, while SMS Authentication is not.
For some users, a sensible long-term security setup may therefore be:
email + strong password + Google Authenticator + identity verification, without relying on SMS as the primary security method.
That reduces dependence on continued access to a specific mobile number.
A virtual number does not replace KYC
Phone verification and identity verification are completely separate.
Bybit currently requires at least Standard Identity Verification for its products and services. Standard verification includes an identity assessment and proof of identity, with higher levels adding proof of address or enhanced due diligence.
A virtual number therefore does not:
- verify your identity;
- replace an ID document;
- replace proof of address;
- change your nationality or eligibility;
- make an unavailable regional product available;
- bypass Bybit compliance checks.
Using a number from another country does not make you a resident or citizen of that country.
What about a phone number for Bybit Card?
This is a useful distinction because the phone number associated with Bybit Card may not always be the same thing as the phone number on the main Bybit account.
During a Bybit Card application, some card programmes may ask the user to confirm or provide a mobile number. If the number is not eligible, Bybit says a supported number can be entered instead. Card eligibility itself still depends on factors such as country of residence and identity verification.
For some Bybit Card regions, personal card information such as the billing address and mobile number operates independently from the main Bybit account.
So when somebody searches for a “Bybit phone number”, it matters whether they mean:
the number linked to the exchange account or the number used for Bybit Card.
They are not always the same.
Can a virtual number give you access to Bybit Card in another country?
No.
Bybit Card is only available in supported countries, and the application includes checks involving country of residence and identity verification. A different phone number does not override those requirements.
A virtual number can solve a phone-verification problem where an eligible mobile number is requested. It cannot change product eligibility.
Is a one-time number safe for a Bybit account?
It depends on what you are using it for.
For a single verification code, a temporary private number can be convenient.
For a mobile number that will stay attached to a financial account, the trade-off is different.
Once the one-time activation ends, you no longer control that phone. If Bybit later requires the number during a security change or recovery process, you may need to use its account-recovery procedures instead.
A simple decision guide is:
| If you need... | Better choice |
|---|---|
| One Bybit SMS code | One-time SMS activation |
| One-off phone verification | One-time activation |
| Keep the number linked | Long-term virtual number |
| Receive future SMS | Long-term virtual number |
| Regular SMS Authentication | Long-term number or personal SIM |
| A primary account holding significant assets | A number with reliable long-term access |
Should you use a free public SMS number?
Not for a financial account.
Public SMS inboxes create obvious security problems: other people may be able to see incoming messages, and the number may already have been used by another Bybit user.
That second point is particularly important because Bybit only allows one account per mobile number.
A private one-time activation prevents the verification message from being displayed publicly. A rented number additionally keeps the phone under your control for the duration of the rental.
Which option makes sense for you?
If your situation is: “I only need one Bybit verification code.” Choose a one-time Bybit SMS activation. Revosim currently lists Bybit as a dedicated supported service.
If it is: “I want a separate Bybit number and may need it again.” A long-term virtual number is the more logical product. Revosim currently offers 30-day and 365-day rental plans for supported countries.
And if it is: “This is my main financial account and I will keep meaningful assets there.” Use a number you can reliably maintain over the long term, and do not make SMS your only security method.
The bottom line
A phone number is not required just to create a Bybit account because registration by email is available and is actually recommended by Bybit. A phone becomes relevant when you choose mobile registration, enable SMS Authentication or use another feature that explicitly asks for verification.
Revosim offers two different approaches: one-time Bybit SMS activation for receiving a single code and long-term virtual-number rental when you want continued access to the same phone.
The main thing to decide is not simply “virtual or personal?”, but how long you will need access to that number.
And remember that a virtual phone number only solves the phone-verification step. It does not replace Bybit KYC, change your identity or make an otherwise unavailable product accessible in your region.
Frequently Asked Questions
Does Bybit require a phone number?
Not for every account. Bybit allows registration by email or phone and currently recommends email registration.
Can I use a virtual number for Bybit?
Potentially. Revosim currently lists Bybit as a dedicated SMS-activation service, but acceptance of a particular number ultimately depends on Bybit.
What is better: one-time SMS activation or a long-term virtual number?
Use one-time activation if you only need one code. Choose a long-term number if you expect to need access to the same phone again.
Can I add a phone number after registering with email?
Yes. Bybit allows users to bind a mobile number later through the account security settings.
Why am I not receiving my Bybit SMS?
Check network reception, SMS storage, blocking apps and carrier restrictions. Also check whether your verification method is set to WhatsApp OTP rather than SMS.
Why did my Bybit code arrive on WhatsApp?
Bybit now supports WhatsApp OTP. If WhatsApp was selected and successfully verified during the first security check, it becomes the default delivery channel.
Can the same phone number be used for two Bybit accounts?
No. Bybit states that one mobile number can only be linked to one account.
Can I change my Bybit phone number?
Yes. You can change it through the security settings after completing the required verification steps.
What happens after I change my number?
Bybit restricts withdrawals, internal transfers, Bybit Card transactions and certain P2P functions for 24 hours after the mobile number is changed.
What if I lost my old phone number?
Use Bybit's self-service account recovery flow and select the option indicating that your mobile authentication method is no longer available. Additional verification may be required.
Does a virtual number replace KYC?
No. Bybit currently requires at least Standard Identity Verification for its products and services.
Is the Bybit Card phone number the same as my account phone?
Not necessarily. In some Bybit Card programmes, the card's mobile number operates independently from the main Bybit account phone.
Can a foreign virtual number make me eligible for Bybit Card?
No. Card availability and eligibility depend on supported countries and identity-verification requirements, not simply the country code of the phone number.
