Best virtual numbers for OpenAI/Chatgpt

Published On: 23/04/2025

However, to access this powerful platform, users must complete a phone verification process during registration. For many, using a personal phone number is undesirable due to privacy concerns, regional restrictions, or the need for multiple accounts. This is where virtual phone numbers come into play, offering a secure, anonymous, and convenient solution for OpenAI/ChatGPT verification.

This comprehensive guide explores the best virtual number providers for ChatGPT verification, detailing their features, pricing, country availability, and ease of use. We focus on five leading services: Grizzly SMS, AnonymSMS, OnlineSim, SMSBower, and 5sim, which have proven reliable for obtaining virtual numbers to bypass restrictions and ensure seamless registration.

Why Use Virtual Numbers for OpenAI/ChatGPT?

Virtual phone numbers are temporary or disposable numbers that operate over the internet, eliminating the need for physical SIM cards. They are particularly useful for ChatGPT verification due to the following benefits:

Privacy Protection: Using a virtual number prevents your personal phone number from being stored in databases, reducing the risk of spam, marketing calls, or data breaches.
Bypassing Regional Restrictions: OpenAI restricts access in certain countries, such as Russia, Belarus, Iran, Afghanistan, Venezuela, and Ukraine. Virtual numbers from supported countries (e.g., the United States, United Kingdom, or Georgia) allow users to register despite these restrictions.
Multiple Account Creation: For users needing multiple ChatGPT accounts (e.g., for business, testing, or development), virtual numbers enable easy registration of additional profiles.
Cost-Effectiveness: Virtual numbers are often cheaper than purchasing new SIM cards, especially for one-time verifications.
Convenience: These services are accessible online, requiring only an internet connection, and are compatible with various devices and operating systems.

Given these advantages, selecting the right virtual number provider is crucial for a smooth and secure ChatGPT registration experience.
