Top 5 Services That Provide Phone Numbers for AI Tools

AI platforms like ChatGPT, Claude, Gemini, and Midjourney require phone number verification to prevent spam and secure user access. Many users, however, prefer to keep their personal phone numbers private or need a way to bypass country restrictions when creating accounts — making virtual phone numbers for AI tools a practical and safe solution.

These services act as secure intermediaries, allowing users to receive SMS codes instantly without revealing personal data. They’re ideal for privacy-conscious individuals, testers, and developers managing multiple AI accounts. Still, it’s important to use them responsibly and ethically, as misuse or spam-related activity can lead to account bans or policy violations.

How We Chose the Best Virtual Number Services for AI Verification

Choosing the right virtual number provider for AI tool verification depends on several key factors that directly affect usability, privacy, and success rate. Below are the main criteria used to evaluate each platform:

• Availability for AI-related verifications:
  The platform must support verification for popular AI tools such as OpenAI (ChatGPT), Claude, Midjourney, or Gemini. Some services restrict access to certain platforms — a critical consideration for users who rely on multiple AI systems. 
• Global coverage:
  The best providers offer numbers from dozens of countries, allowing users to bypass regional restrictions and select locations most accepted by AI verification systems. 
• Message delivery speed:
  Instant or near-instant message reception ensures users can complete the sign-up process without timeouts. Fast message processing is especially important when codes expire quickly. 
• Privacy and security level:
  Reliable providers encrypt traffic and avoid exposing personal data. Preference is given to platforms offering private or temporary numbers to minimize visibility risks. 
• Pricing transparency and ease of use:
  Clear pricing models and simple interfaces reduce confusion. Many users value one-click verification workflows or dashboard-style layouts that show messages immediately upon arrival.

Security and Legal Considerations

Using virtual numbers for AI verification is completely legal when done for legitimate purposes, such as creating or confirming accounts on platforms like OpenAI, Midjourney, or Claude.

However, these tools’ providers and the number of services themselves maintain strict anti-fraud systems. Any suspicious activity or repeated account creation may result in blocks or bans.

Users should remember:

• Never store personal or API-sensitive information in public SMS inboxes, as messages are visible to anyone. 
• For business or team accounts, prefer private or premium numbers to protect login data. 
• Check local regulations — privacy and telecom laws vary by country, and some regions restrict shared-number verifications.

Tips for Successful Verification

To ensure your AI account verification goes smoothly and without wasted credits, keep these expert-backed strategies in mind:

1. Refresh the inbox frequently.

AI tools such as OpenAI or Midjourney often send verification codes that expire within seconds or minutes. Keeping the inbox open and refreshing it ensures you don’t miss these short-lived SMS codes.

2. Choose private or paid numbers for consistent results.

Public numbers can be overloaded or blocked due to repeated verifications. Private or paid options typically guarantee faster delivery, higher success rates, and better privacy — especially when setting up multiple AI accounts or managing sensitive projects.

3. Match the country with the AI tool’s availability.

Some AI platforms only allow phone numbers from specific countries. Always check compatibility before selecting your virtual number to avoid failed verifications or blocked access.

4. Avoid reusing the same number for different AI platforms.

Reusing numbers can trigger duplicate account detection systems. Opt for a new number each time to ensure a smooth registration process.

5. Keep records of successful verifications.

If you’re managing multiple AI tools or testing automations, note which services and numbers worked — it’ll save time in future verifications.

Conclusion

Virtual number services have become indispensable tools for anyone working with or exploring modern AI platforms. They provide the flexibility, privacy, and reliability needed to manage verifications across multiple systems — from ChatGPT to Gemini — without exposing personal information.

The best options, such as SMSFAST, 5SIM.net, and OnlineSim, combine global coverage, fast code delivery, and clear pricing, making AI tool verification smooth and secure. When used responsibly, these services are not just convenient — they’re a smart safeguard for maintaining privacy in the age of AI.
