Can I use Claude without phone number? Not when creating a new Claude account. Anthropic currently requires new users to verify a phone number from a supported location by SMS before account creation is completed.
This requirement applies to new Claude accounts, including users who plan to use the free plan. An email address or Google sign-in does not currently provide a documented way to skip phone verification.

The important distinction is between creating a Claude account and signing into an existing Claude account. Existing Claude users can normally authenticate with Google or a secure email login link without entering their phone number each time.
The same distinction applies to web access, mobile apps, paid plans, and the Anthropic API. Each uses related Anthropic services but can have different onboarding and authentication requirements.
Current Claude Phone Verification Requirement
Anthropic currently requires phone verification for all new Claude users. The verification process confirms that you control an eligible phone number before Claude finishes creating the account.
The process is simple:
- Enter a phone number from a supported location.
- Receive a verification code by SMS.
- Enter the latest code in the Claude verification form.
- Complete account registration.
Anthropic says the phone number must be able to receive text messages. VoIP numbers, Google Voice numbers, landlines, numbers created through apps, and other numbers that cannot receive SMS are not accepted.
This means an email-only registration is not a supported option for a new consumer Claude account. If you do not have an eligible phone number, there is currently no official method to skip the verification step.
The requirement is separate from email authentication. Email helps users access an account, while phone verification is part of the new-account registration process.
Why does Claude require a Phone Number?
Anthropic says phone verification helps prevent spam and abuse. Requiring a working mobile number makes automated or repeated account creation more difficult.
Phone verification should not be confused with full identity verification. A verified phone number indicates that a user can receive messages at that number, but it does not, on its own, establish a person’s legal identity.
Some Claude users may encounter additional identity checks for specific capabilities or account situations. Those checks are separate from the standard phone verification used when creating a new account.
Can I use Claude without Phone Number for an Existing Account?
Yes, an existing verified Claude account can normally be used without entering the phone number during every login. Claude currently offers Google authentication and email-based authentication for account access.
With email login, Claude sends a secure sign-in link. If the link is opened on the same device used to request it, the user can normally enter the account directly; using another device can require a verification code.
Google sign-in works differently because authentication takes place through the user’s Google account. However, Google authentication does not remove the phone requirement for creating a new Claude account.
This distinction resolves much of the confusion around Claude phone number login. Phone verification is primarily a registration requirement, while Google and email are normal authentication methods for an existing account.
Claude does not currently provide a dedicated account password that users create themselves. Users authenticate through the available sign-in methods instead.
Can I Create a Claude Account without a Phone Number?
For a new Claude consumer account, no. Anthropic currently states that new users must have a phone number capable of receiving an SMS verification code.
There is also no documented email-only, Google-only, or Apple-only registration route that bypasses this requirement.
Apple users can use Apple’s Hide My Email feature when an account has been created with a private relay address. That can affect the email address used for authentication, but it does not replace phone verification during new account creation.
If your concern is privacy, consider what Anthropic requires to decide if their service meets your needs. Using a fake, borrowed, stolen, disposable, or unauthorized number creates account and security risks and is not a legitimate solution.
Does Google sign-in Remove Phone Verification?
No. Google sign-in changes how you authenticate, not the requirements for creating a new Claude account.
A new user can select Google as a sign-in option, but Anthropic may still require phone verification before the account is fully usable.
For existing users, signing in with Google can simplify access since they authenticate using their established Google account. This process differs from registration, where Claude continues to enforce its current verification procedures.
The same principle applies to other authentication choices. An authentication method tells Claude who is accessing an existing account; it does not automatically remove registration requirements.
What if Claude Phone Number Verification is not Working?

If Claude phone number verification is not working, first check the number, country selection, SMS capability, and your current location. Do not keep testing random numbers or attempt to bypass the verification system.
A verified phone number indicates that a user can receive messages at that number, but it does not, on its own, establish a person’s legal identity.
If you see an error such as “Error sending code. Double-check your phone number,” check that the number:
- Comes from a supported location.
- Can receive SMS messages.
- The number must be a standard mobile number, not VoIP service.
- It should include the correct country code.
- Additionally, it must not be linked to another Claude account.
If the code arrives but fails, use the newest code rather than an older message. Verification codes are temporary, so requesting several codes can make older codes unusable.
If a valid number continues to fail, contact Anthropic Support. Keep the exact error message available because it can help support staff identify the problem.
What does “Phone Number Used too Recently” Mean?
A message indicating that a phone number has already been used or has been used too many times typically means that the number is already linked to a verified Claude account.
If you own that existing account, sign in to it and contact Anthropic Support about unlinking the number. If you do not control the existing account, do not attempt to take over its verification history.
A different legitimate mobile number may be appropriate if Anthropic allows it and the number meets the current requirements. The goal should be to resolve the account association, not defeat the restriction.
Anthropic also says that the phone number associated with a Claude account cannot simply be changed after verification. For that reason, use a number you expect to control for the long term.
Can I use a Virtual Phone Number for Claude?
A virtual phone number is not a reliable or supported solution for Claude registration. Anthropic specifically excludes VoIP numbers, Google Voice, app-generated numbers, landlines, and other numbers that cannot receive the required SMS.
That matters because many online guides recommend temporary or virtual numbers. Such advice can be outdated, incompatible with Anthropic’s current rules, or unsafe for account recovery.
If you need Claude for legitimate work, use a mobile number that you control and that satisfies Anthropic’s current requirements. Do not use public SMS inboxes, numbers belonging to strangers, stolen numbers, or unauthorized OTP services.
Privacy-conscious onboarding should reduce unnecessary exposure without defeating security controls. If your organization has strict privacy requirements, document the requirement and evaluate whether Claude’s current registration model is appropriate before creating accounts.
Do Requirements Vary by Country?
Yes. Claude access depends on supported locations, and Anthropic requires the phone number used for new account verification to be from a supported location.
Users must also be physically located in a supported location to create and use Claude accounts. This means geographic availability is separate from the phone number itself.
For example, having a number from a supported country does not automatically make registration legitimate if the user is physically outside Anthropic’s supported locations.
Country availability may vary, so users should verify Anthropic’s current supported locations if registration fails due to geographic restrictions.
Do not treat a VPN, proxy, browser setting, or similar network change as a legitimate solution to regional restrictions. If Claude is unavailable where you are located, the appropriate option is to wait for official availability or use another service that supports your location.
Is Mobile Signup Different from Web Signup?
Claude is available through the web, desktop applications, and mobile applications. The interface differs by platform, but mobile access does not provide a documented exemption from the new-user phone requirement.
A user with a Claude account can access it on all supported devices. Signing into Claude on a phone does not require creating a separate mobile-only account.
The practical difference is therefore the device, not a separate registration policy. If the account is new, expect the current verification requirements to apply regardless of whether registration begins on the web or through an official mobile application.
Users should also make sure they download the official Claude application rather than an unofficial application that requests unnecessary account information.
Can I use Claude AI without Loging In?
For the official Claude consumer service, users should expect to use an account. Claude’s web, desktop, and mobile experiences are designed around authenticated accounts.
A third-party website may offer access to a Claude-powered feature without requiring a direct Claude account, but that is not the same as using the official Claude service. Third-party providers can impose their own limits, pricing, privacy policies, and authentication requirements.
This distinction is important when comparing “Claude without login” claims online. A third-party interface does not prove that Anthropic allows unauthenticated access to Claude.
If you want the official Claude experience, plan around account registration and authentication requirements rather than relying on an unofficial front end.
How long can you use Claude.Ai for Free?
Claude has a Free plan, but free access is usage-limited rather than unlimited.
Anthropic currently describes the Free plan as having a session-based usage limit that resets every five hours. The number of available messages may vary based on demand, and Anthropic may impose additional limits to ensure fair access.
This means there is no useful fixed answer such as “Claude is free for 30 days.” The Free plan is ongoing, but the amount you can use depends on the current limits and product policies.
Paid plans provide higher usage allowances and additional capabilities. However, paying for Pro, Max, Team, or Enterprise does not create a documented exemption from the phone-verification requirement for a new account.
Does the Anthropic API Require the Same Setup?
No. The Anthropic API and the consumer Claude service are separate access paths.
Developers use Claude Console to manage API access, Workbench activity, organizations, and API credentials. Console login currently supports Google and email authentication, and developers use API keys or supported cloud-provider authentication for applications.
A Console account is not the same as a consumer Claude account. A person can have both, even when they use the same email address.
This does not mean the Anthropic API is a guaranteed phone-free alternative. Console onboarding, billing, organization settings, geographic availability, security checks, and future verification requirements can differ from consumer Claude.
If your goal is to build software with Claude rather than chat with Claude directly, evaluate the API workflow separately. Do not assume that an API account is a way to bypass consumer registration controls.
What are the Privacy-Conscious Options?

If privacy is your concern, focus on legitimate account-management choices rather than verification workarounds.
Use an email account you control and expect to keep. Account recovery becomes harder when users register with temporary addresses or accounts they cannot access later.
Use a legitimate mobile number that you control. Avoid numbers obtained solely to defeat account limits or verification requirements.
For organizations, separate personal and business access where appropriate. Establish who owns the account, who controls recovery information, who can access subscriptions, and how the organization handles AI data.
It’s important to differentiate between authentication and data privacy. A secure login does not guarantee that all types of information shared with an AI service are suitable for every business application.
Before adopting Claude for sensitive workflows, review Anthropic’s current privacy terms, security documentation, internal policies, and applicable regulatory requirements.
What should you do when Registration Fails?
If you cannot complete Claude registration, identify the specific failure before changing anything.
SMS not received: Confirm that the number can receive normal text messages, wait several minutes, and use the retry option.
Invalid number: Check the country and number format, then confirm that the number is not VoIP, a landline, or another unsupported type.
Number already used: Identify whether the number belongs to an existing Claude account and contact Anthropic Support if you need help with an existing association.
Unsupported location: Check whether your physical location is currently supported. Do not attempt to disguise your location to defeat the restriction.
Email login failure: Check spam, junk, quarantine, and corporate email filtering. Business, government, and educational email systems can sometimes block automated login messages.
Persistent errors: Record the exact message and contact Anthropic Support rather than repeatedly attempting different verification methods.
This approach solves the actual onboarding problem while keeping account access legitimate and recoverable.
Can I use Claude without Phone Number? The Practical Answer
For a new Claude consumer account, the current answer is no: Anthropic requires phone verification from a supported location. For an existing account, normal authentication can use Google or secure email login without entering the phone number during every sign-in.
If your problem is registration, use a legitimate eligible mobile number, confirm that your location is supported, and follow Anthropic’s verification process. If the system rejects a number that should qualify, contact support instead of trying to bypass the control.
For companies, the bigger question may be which Claude access model fits the business. Consumer Claude, paid plans, Team or Enterprise access, and the Anthropic API have different workflows and operational considerations.
Flexlab can help you review those requirements before your team commits to an AI workflow. To evaluate an approach that balances access, privacy, collaboration, authentication, and operational requirements.
