Hi Mingchuan,
Thanks for reaching out to Microsoft Q&A.
There could be several reasons why you are not eligible for a free Azure account. Here are a few possible reasons:
- You may have already used up your free trial period: Azure offers a free trial period of 12 months for new customers. If you have already used up your free trial period, you may not be eligible for another free account.
- You may have already signed up for a free account with the same email address: Each email address can only be used once to sign up for a free Azure account. If you have already signed up with the same email address, you may not be able to sign up again.
- You may have provided invalid or incomplete information during the sign-up process: Azure requires certain information to verify your identity and eligibility for a free account. If you provided incorrect or incomplete information during the sign-up process, your account may not have been approved.
- You may be located in a country or region that is not eligible for a free account: Azure offers free accounts in certain countries and regions. If you are located in a country or region that is not eligible for a free account, you may not be able to sign up for one.
