Can I verify OpenAI with a free temporary phone number?

OpenAI was founded in 2015 with the goal of developing artificial intelligence that benefits everyone. Today, its products are used by hundreds of millions of people around the world, with ChatGPT being its best-known service.

Although a private number offers the highest chance of success, even a free temporary phone number may occasionally work for OpenAI SMS verification, depending on their verification policies at the time of registration. If free numbers are not accepted, it's best to create an account at our site and obtain a private number to complete the verification process.

Does Claude accept temporary phone numbers for verification?

Claude is one of the leading AI assistants and is designed with a strong focus on helpful, safe, and natural conversations. Although they are very strict about verification, in some cases Claude can be verified using a free temporary phone number when SMS verification is required during registration. Whether a particular number is accepted depends on Anthropic's automated checks, so trying another number may help if your first attempt is unsuccessful.

Will a free temporary number work for Cursor AI?

Cursor is a popular AI-powered code editor built on VS Code. A free temporary phone number can often be used for verification, although success depends on the specific number available at the time. Keep in mind that free numbers may occasionally be rejected if they have been heavily used by other users. If that happens, simply try another number or create an account at our site and obtain a private number for a higher chance of successful verification.
