Can I subscribe to Claude / ChatGPT?
Yes — that is exactly what this BIN is designed for. The issuer explicitly supports AI subscriptions with no merchant-category blocks. Platform data, re-verified monthly: no card-binding verification failures and no proactive issuer rejections seen at OpenAI / Anthropic (latest definition on the AI Payment Compatibility Index page).
The real question behind "can I subscribe?" is this: why does one person bind a card to OpenAI and sail through in seconds, while another gets rejected again and again? The answer is half about the BIN and half about your account — the BIN determines only the card-side half of that experience. When an issuer releases each card range (BIN), it presets a scenario configuration for it: which merchant categories are allowed through, and whether SMS verification is attached. A card whose issuer explicitly supports the AI-subscription scenario and a general-purpose card face completely different treatment on the card side at the very same checkout. How to diagnose and manage the account half is covered separately below, under "Where our responsibility ends."
Our US cards (Mastercard / Visa) run on exactly this kind of BIN — one whose issuer explicitly supports the AI-subscription scenario. That "explicit support" rests on four mechanisms, and each one maps to a monthly-verified reconciliation result:
Four mechanisms, mapped to four monthly-verified reconciliation results
| Mechanism | Description | Reconciliation result (re-verified monthly) |
|---|---|---|
| Merchant category allowed | AI merchants such as OpenAI / Anthropic sit on the BIN's list of permitted categories, so the category gate blocks nothing | no category blocks seen for AI subscription merchants |
| Subscription scenario support | A fixed $20-level amount billed on a monthly recurring basis is the standard subscription-spending pattern, and the issuer explicitly supports this scenario | no proactive issuer risk-control declines seen in the subscription scenario |
| No SMS verification for card binding or charges | Unattended renewal charges never break at the verification-code step (see the next section) | no card-binding verification failures seen |
| Billing address by card range region | One is assigned per card by its card range's region (a US address for US ranges), viewable and editable on the card detail page | no AVS failures seen |
These BINs are also a shared resource for every user: once a BIN's reputation is dragged down by abuse, the whole range's treatment on the merchant side deteriorates. The cap on cards per account (by default 5 active at a time and 5 in total for a new account, raised step by step with genuine usage) exists precisely to protect that reputation.
No SMS verification: a must-have for overseas subscriptions, not a nice-to-have
A subscription charge is, at its core, an unattended recurring charge: after the first card binding, every monthly renewal is initiated automatically by the merchant while you are not present. 3DS verification (SMS / app confirmation) happens mainly at the card-binding and first-charge steps — and once it triggers, if you can't receive the overseas verification code, the transaction freezes on the verification page and the subscription can't even get off the ground. A 3DS-free BIN removes this step entirely: from card binding, to the first charge, to every monthly renewal, you never have to sit by your phone.
Where our responsibility ends: we guarantee the card side, you manage the account side
A subscription has to clear two gates. Gate 1 is the merchant platform's up-front risk control, which weighs how new the account is, its usage history, and IP quality. Only Gate 2 is the issuer, which checks limit, balance, and card details. The four reconciliation results in the table above show no mechanism-level blocking at Gate 2, at the mechanism level — failures caused by limit, balance, or card details still occur, but those you can fix yourself in a few minutes; they are not the mechanism blocking you. So nine times out of ten, a rejected card binding is stuck at Gate 1: the account is too new or the IP too poor, and the request never even reached the issuer. Diagnosis takes just one minute: open the spending detail on the card detail page — a failure record means it reached the issuer, so handle it by the specific reason; zero records means merchant risk control is blocking your account, and swapping cards won't help. This part is outside the card's control; we make no promises about it, and please don't trust any "guaranteed success" pledge either.
Pre-subscription checklist
- Fund the limit at the tax-inclusive price: a US $20 plan actually costs $20–22 to pay (some states charge sales tax), and the 30 USD minimum card-opening limit covers the tax, back-charge and API-purchase patterns; if it's not enough, you can top up the card at any time (service fee from 2%, tiered by monthly volume down to 0.5%, credited instantly).
- Don't use a "blank-slate" account: prefer a merchant account with usage history, since binding a card on the same day you register is the surest way to trip up-front risk control.
- Get the network right the first time: a residential IP, with no node-switching anywhere from card binding through charging.
- Match the billing address word for word: align the checkout-page address character for character with the billing address registered on the card detail page — use the copy button, and watch out for the browser autofilling an old address back in.
- Copy card details, don't type them by hand: a mistyped expiry date / CVC, declined right at the charge step — the most avoidable kind of failure.
- Diagnose before you retry: a real case — rejected 8 times in 7 minutes for the same reason, then, after stopping to adjust the limit, the same amount went through on the first attempt 5 minutes later; on card ranges that charge a failed-transaction fee, each failure costs an extra $0.60 (some ranges don't charge it; the card-opening page itemizes it), so clicking over and over is just paying to bang against a wall.
