How to Sign Up for Claude from Russia

Claude by Anthropic is a powerful AI assistant for analysis, programming, and text generation. The model is known for its large context window and strong reasoning and analytical capabilities.

However, because of regional restrictions, registering for the service from a number of countries is no longer a simple task. In the guide below, we discuss the account creation process and the pitfalls for users from Russia, so that you do not waste time and nerves.

Is Claude available in Russia?

Officially, no. The service cannot be used in Russia. Anthropic provides access to the API and Claude.ai only to users from supported countries and regions, so the supported locations list should be checked separately before registration.

Russia is not in the current list of supported locations for Claude.ai. This means the issue is not only about receiving an SMS code, but also about the service availability rules themselves.

As a result, a Russian mobile number (+7) alone is not enough for registration: Anthropic requires a number from a supported location that can receive SMS. The main restriction is connected with Claude availability in the user’s country and phone verification.

Important: even if claude.ai opens in the browser, this does not mean that a profile can be created, the user can log in, or a subscription can be paid for. Restrictions apply to the account, phone verification, and further use of the service.

How Claude registration works where the service is available

If the user is physically located in a supported country and has an eligible phone number, the registration process usually looks like this:

• Create an account. Go to claude.ai, enter an email address, and create a password. After that, the system will ask you to confirm the email through a link in an automated message. Quick sign-in with Google may also be available.
• Enter a phone number. To protect the service from bots and spam, Claude then asks for a registration number from a supported location. It cannot be changed later, so it is important to use a number to which you can keep long-term access.
• Receive the SMS. The system sends a 6-digit one-time code to the number. To activate Claude, enter it in the field that appears. This completes the check and confirms access to the number.
• Finish registration. After the code is entered, the system completes account creation and opens access to conversations with the AI if the service conditions are met.
• Check service access. After login, make sure Claude opens without errors. If the service shows a country or phone number restriction, continuing registration is not advisable.

Can you use a virtual number for Claude?

Claude account registration and confirmation may require a phone number that can receive an SMS code. Some services, including Revosim, offer one-time SMS numbers specifically for Claude: the user chooses a country, receives a number, and gets the code online.

At the same time, it is important to understand that having a number in such a service does not mean a 100% guarantee of successful registration. Anthropic states that VoIP numbers, Google Voice, numbers created by apps, landlines, and other options that do not support SMS cannot be used for verification. Therefore, the result depends on how Claude’s system identifies a specific number at the moment of verification.

If the number is suitable, the user will be able to receive the SMS code and complete confirmation. If Claude recognizes the number as unsupported, an error may appear when sending the code, or the service may ask for another number.

Revosim in this case can be considered a service for receiving SMS codes on virtual numbers for different platforms, including Claude. But the decision on whether to accept the number remains with Anthropic.

What to do if the Claude verification code is not received

If you are at the SMS entry stage but the message with the code does not arrive, you can try the following:

• Wait a few minutes. The code may arrive with a delay. If more than 5 minutes have passed, it is better not to press resend many times in a row; re-enter the number and request a new code.
• Check the entered data. Make sure the correct country code is selected, the number has no typos, and it belongs to a supported location.
• Use the newest code. SMS codes are temporary. If you request a new code, the old one may no longer work, so enter the most recent message.
• Try another eligible SMS number. If the message does not arrive or Claude says that the code could not be sent, the last option is another number that meets Anthropic’s requirements.

Important: if Claude is not available in your location, you should not try to bypass restrictions in an unsupported country. This can lead to account creation errors, repeated checks, or access limitations.

What is the conclusion?

Here is a short checklist with the main points:

• Claude is not officially available in Russia. Before registration, check Anthropic’s current list of supported countries and regions.
• Registration requires an eligible phone number from a supported location. Phone verification cannot be skipped, and after confirmation the number cannot be changed.
• For verification, Anthropic sends a 6-digit SMS code. The number must be able to receive text messages, and long-term access to it is preferable.
• VoIP numbers, Google Voice, app-created numbers, landlines, and other numbers without SMS reception may be rejected by Anthropic.
• Revosim can be useful as a service for receiving SMS codes on virtual numbers. During Claude registration, such a number can be tried for confirmation, but the final check always happens on Anthropic’s side, so successful SMS delivery does not always mean guaranteed account registration.
• If the code does not arrive, wait a few minutes, check the number, and use another eligible number rather than trying to bypass restrictions.

Claude registration depends on Anthropic’s rules: the service is not available in all countries and regions. Russia is currently not included in the supported locations for Claude.ai, so a phone number alone is not enough for verification. Verification requires a phone number from a supported location that can receive an SMS code.
