Selected country: Viet Nam (+84). This page matches OpenAI with that country selection so you can review the relevant temporary phone number option before continuing.
OpenAI is the AI research company behind ChatGPT, GPT-4, and the OpenAI API. Access to ChatGPT and the API developer platform requires account verification via phone number to prevent abuse and ensure fair usage limits.
OpenAI requires SMS verification when creating accounts for ChatGPT or accessing the API platform. A SimCode virtual number lets you register for OpenAI services, set up developer API keys, or create additional accounts for testing.
Vietnamese virtual numbers use the +84 country code and serve one of Southeast Asia's fastest-growing digital markets. Vietnam's mobile-first economy relies heavily on apps like Zalo, MoMo, and Shopee, all of which require local Vietnamese phone verification.
Vietnamese +84 numbers connect through local carriers and are required for accessing Vietnamese social, payment, and e-commerce platforms.
You can get temporary phone numbers in Viet Nam for websites, apps, and internet services.
You will be able to view the price per action after selecting the service and country.
