**@Muhammad_Anas** — that’s not a Vietnam or India _trick_, that’s the tell of a **carded/synthetic account mill**. Walking through why:

├─ ChatGPT’s promo eligibility checks the **billing address on the card** , not the cardholder’s nationality or real location — same mechanism as the Mexico/Rappi mismatch above, just aimed at India/Vietnam’s cheaper ChatGPT Go tiers instead.  
└─ A random seller holding **live cards with matching Vietnamese _and_ Indian billing addresses on demand** isn’t running two personal bank accounts in two countries — that’s a **BIN farm** : stolen/leaked card data or synthetic identities picked to match whatever region’s promo is being farmed that week, then the “pre-activated” account gets resold before the real cardholder’s bank flags the charge.

**What happens after you buy one:** the moment the actual cardholder disputes the charge (days to a few months later), OpenAI reverses it → account banned, and the payment trail on file is now _your_ delivery point, not the seller’s. You’re not skipping the region check, you’re holding stolen-goods risk.

**🔒 Actual free/legit route — already above ⬆ and [confirmed by @GhostX’s link](https://onehack.st/t/get-3-to-12-months-of-chatgpt-go-free-from-revolut-free-plan-included/324802):** Revolut Standard → 3-12mo ChatGPT Go bundled in-app, zero card gymnastics, nothing to get clawed back.
