Complete Guide to Subscribe to ChatGPT Plus: Step-by-Step Registration & Payment

ChatGPT Plus is a paid subscription service from OpenAI that offers access to the GPT-4o model, faster response times, and priority access. For users in China, successfully registering, linking a payment method, and activating a Plus membership can be challenging. This tutorial walks you through the entire process from scratch, helping you avoid common mistakes.

Register an OpenAI Account & Basic Setup

To subscribe to ChatGPT Plus, you first need an OpenAI account. If you don't have one yet, go to the official ChatGPT website and click "Sign Up". It is recommended to use a Gmail or Outlook email address to avoid issues with receiving verification codes from domestic email providers. Registration requires phone verification, but many country codes are blocked. It is advisable to use an SMS verification platform (e.g., sms-activate.org) to get a temporary number — choosing numbers from India or Brazil has a higher success rate. After completing email and phone verification, your standard account will be created.

Choose a Payment Method for ChatGPT Plus Subscription

Once your standard account is ready, log in and click "Upgrade to Plus" in the bottom-left corner to access the payment page. ChatGPT Plus currently accepts credit and debit cards, but Visa/Mastercard cards issued in China often fail for direct payments. The most reliable solution is to apply for a virtual credit card (e.g., Depay, OneKey), top it up, and then link it to your OpenAI account. Make sure the card supports 3DS verification, otherwise you will get an error. PayPal can also be used, but you need a US or EU PayPal account — accounts registered in China generally won't work.

Link Your Card & Complete the Subscription

On the payment page, select "Credit/Debit Card", then enter your virtual card number, expiration date, and CVV. It is recommended to use a billing address in a US tax-free state (e.g., Oregon) to avoid extra taxes. After submitting, OpenAI will charge $20 as a pre-authorization verification and then refund it before the actual charge is made. If you see a "Your card has been declined" message, check that your card has sufficient balance, supports international payments, or try switching to a US native IP. Once the charge succeeds, your account is immediately upgraded to Plus, and you can start using GPT-4o and other advanced features right away.

Switch Accounts & Multi-Device Usage Tips

ChatGPT Plus subscription is tied to your account. One Plus account can be used on the web, iOS, and Android apps. To switch accounts, click your profile picture in the bottom-left corner and select "Log out". Avoid frequently switching IPs or logging in from multiple devices at the same time to prevent triggering security locks. If you need to share Plus benefits with other accounts, you could consider family sharing (though it's not officially supported — proceed at your own risk).
