If your office pays for ChatGPT with one company card, or your team keeps a few paid accounts on one laptop, two changes from OpenAI matter to you this month. First, ChatGPT now limits how many paid accounts can share one payment card or one device. Second, from December, Plus, Pro and Business plans will draw ChatGPT and Codex usage from one shared allowance. Here is what OpenAI's own help pages say, what has been reported, and a simple plan for Indian teams. Every fact is linked.
1. What changed, in one minute
On November 1, 2026, The Decoder reported that OpenAI is adding card and device limits to ChatGPT "as part of its security measures" (The Decoder). The same day it reported that, starting in December, Plus, Pro and Business plans will share one token budget across ChatGPT and Codex, citing an updated OpenAI support page (The Decoder). Both changes are described on OpenAI's Help Center:
- Understanding card and device limits in ChatGPT: what happens when too many subscriptions sit on one card or device.
- Understanding ChatGPT and Codex usage limits: how the shared allowance will work from December.
A post on OpenAI's developer community forum on November 1 also flagged the December change ahead of time and linked to the same help page (OpenAI Developer Community).
2. The new card and device limits
OpenAI says ChatGPT uses card and device limits "as part of its privacy and security protections." In practice, according to the help page (OpenAI Help Center):
- Card limit: if too many subscriptions are linked to the same payment card or device, ChatGPT may block a new purchase. Checkout then shows: "Too many subscriptions associated with this card or device. We can't complete this purchase." OpenAI notes this is not a bank decline.
- Device limit: ChatGPT also limits how many paid accounts can be used on one device. If you see Device limit reached, that paid account cannot be used on that device. The warning can appear at sign-in, or you can be signed out after a later check, "even if the purchase went through and the account worked at first."
- Which plans count: ChatGPT Go, Plus, Pro 100, Pro 200 and Pro 500. Free accounts and the Business, Enterprise and Edu workspace plans do not count toward the device limit.
- Signing out does not free a slot: the device limit is separate from how many accounts are signed in at once.
- Credits will not fix it: buying credits or resetting usage "won't clear a card or device restriction."
OpenAI does not publish the exact number of accounts allowed per card or per device on that page, so we will not guess one. It does say that subscriptions bought before these restrictions take effect can continue under an "existing-subscription exception," but cancelling one does not guarantee you can replace it.
The Decoder's reading is that the policy will mostly hit people who switch between several cheap paid accounts on one device to get more usage, and that OpenAI points them to credits or usage resets instead (The Decoder).
3. From December: one allowance for ChatGPT and Codex
The second change is about how much you can use, not how many accounts you hold. OpenAI's help page says that starting in December, the usage allowance on Plus, Pro and Business plans "will be shared across ChatGPT and Codex as we bring the agentic capabilities of Work into the main ChatGPT experience" (OpenAI Help Center). Key points from that page:
- Usage will be measured in tokens. More advanced models and complex tasks generally use more of your allowance.
- Instant chat will not draw from your usage.
- You will see your combined remaining usage and reset times in Settings → Usage.
- If you hit the limit, you can wait for the reset, upgrade your plan, or buy credits for eligible features.
- OpenAI says: "We expect most users won't need to wait for their usage to reset more often than they do now."
Not everyone is convinced. On OpenAI's own community forum, paying users have posted concerns that heavy chat use could now eat into their coding budget in Codex (OpenAI Developer Community). The Decoder notes that OpenAI recently doubled usage limits on higher-priced plans, "presumably to prepare for the merger" (The Decoder). How much this changes your day will depend on how you use the two tools, and we will only know for sure once it rolls out.
4. Who in India is most likely to notice
These are our own examples, based on the rules above:
| Your setup | What may happen |
|---|---|
| One company or founder's card paying for several staff Plus or Pro accounts | A new purchase on that card can be blocked by the card limit, even if each person uses their own laptop (OpenAI's help page mentions this shared-card case). |
| An agency or freelancer keeping several paid client or personal accounts on one laptop | One of them may show "Device limit reached" and stop working on that machine. |
| A shared office PC, family computer or cyber cafe where different people sign in to their own paid accounts | OpenAI says a shared household or public device "can also reach a limit" when people use their own accounts. |
| Developers who use ChatGPT for research and Codex for coding on one plan | From December both draw on one token allowance, so a heavy chat day can leave less for Codex, and the other way round. |
5. What to do now: a simple checklist
- Count your paid accounts. List who uses ChatGPT Go, Plus or Pro in your team, which card pays for each, and which devices they sign in on.
- Move teams to a workspace plan. If several people share one card, a Business workspace is the cleaner route: OpenAI says Business, Enterprise and Edu workspace plans do not count toward the device limit.
- Stop account-hopping on one machine. Do not keep three paid accounts on one laptop to stretch limits. Signing out does not free a slot, and you may be signed out later.
- Do not panic-cancel. Existing subscriptions can continue under the existing-subscription exception, and OpenAI warns that cancelling one does not guarantee you can buy another. Ask Support first if unsure.
- Know the two error messages. "Too many subscriptions associated with this card or device" is a ChatGPT block, not your bank. "Device limit reached" means that account cannot be used on that device.
- Watch Settings → Usage from December. Note how fast heavy reasoning and Codex tasks use the shared allowance, and use Instant chat for quick questions, since OpenAI says it will not draw from your usage.
- If you think a block is wrong, ask Support. Share the warning text, your plan and whether you were charged. Never share passwords, one-time codes or full card details, as OpenAI itself advises.
6. The bottom line
ChatGPT is moving from "buy another account" to "manage one account well." For a small Indian business, that means one clean plan per team, no account juggling on shared machines, and a monthly look at usage once ChatGPT and Codex share one allowance in December. If you are weighing which OpenAI tools are worth paying for, our earlier guides on GPT-6.1 Terra and ChatGPT ads in India may help.
FAQ
What are ChatGPT's new card and device limits?
ChatGPT may block a new subscription if too many subscriptions are tied to one payment card or device, and it limits how many paid accounts can be used on one device. The limits are explained on OpenAI's Help Center page about card and device limits.
Which ChatGPT plans count toward the device limit?
ChatGPT Go, Plus, Pro 100, Pro 200 and Pro 500 count. ChatGPT Free and the Business, Enterprise and Edu workspace plans do not, according to OpenAI's Help Center.
Will buying credits remove a device limit?
No. OpenAI says buying credits or resetting usage won't clear a card or device restriction. Credits only pay for extra usage on an account you can already use.
What changes for ChatGPT and Codex in December?
From December, Plus, Pro and Business plans will share one usage allowance across ChatGPT and Codex, measured in tokens. Instant chat will not count, and you can check combined usage in Settings, then Usage.
Is "Too many subscriptions associated with this card" a bank decline?
No. OpenAI says that message means ChatGPT blocked the purchase because of a card or device restriction. It is different from a card declined by your bank.
