What to know first
Before you take any Plus offer, check three things: where it comes from (a partner, an OpenAI invite or an event email), whether checkout shows the expected price such as $0.00, and what the renewal price and cancellation route are after the promotion. Promo codes cannot be stacked. Web subscriptions are canceled on the web, and App Store or Google Play subscriptions are canceled in that store. The 2026 Back to School student offer had a claim deadline of October 31, 2026, and appears here only as a past example of the rules.
What official ChatGPT Plus offers exist, and where do you check them?
The OpenAI Help Center describes several kinds of Plus offers, each with its own source and limits. The table follows offer type → where to check → main limits; each campaign's terms and the checkout page have the final word. See ChatGPT Plus prices for the regular price.
| Offer type | Where to check | Main limits |
|---|---|---|
| Partner promo code (for example sent by a carrier by SMS or through a partner portal) | The partner's campaign terms; whether checkout shows $0.00 or the expected discount after redeeming | One code per subscriber; not transferable or for sale; some offers are only for people who have never had Plus; may be limited by region or payment method; OpenAI does not reissue codes |
| Friend invite trial (referral code or link) | Campaign details in the invite email or inside ChatGPT | Generally for new users or Free plan users; expiry set by OpenAI; may require a payment method; cannot be combined with other offers |
| OpenAI event or email promo code | Redemption instructions in the email or at the event, and the discount, start date and renewal terms on the confirmation page | For existing subscribers it may start immediately or at the next renewal; cannot be stacked |
| Student offer (2026 Back to School, deadline passed) | The OpenAI Help Center offer page | Only for students at eligible US institutions, verified by SheerID; redeemable once; claim by 2026-10-31 |
| Annual discount | Plus Help Center article | Not available: Plus does not support annual billing or paying for several months in advance |

What should you check before redeeming a ChatGPT Plus promo code?
- Open the unique link from the partner, then sign in to or create the ChatGPT account you want the offer on.
- At checkout, confirm the price shows $0.00 or the expected discount. If it does not, do not complete the purchase; contact the partner that issued the code or OpenAI support with screenshots.
- Some offers apply right away without checkout; in that case, check that your plan and access have updated.
- Common reasons for an ineligible error: you already have Plus, you used a similar promotion before, the code expired, or the offer is not valid in your region or with your payment method.
- OpenAI does not reissue promo codes; contact the partner that gave you the code if it does not work.

Will you be charged when the promotion ends?
Yes. The Help Center says most promotions auto-renew at the standard Plus monthly rate after the promotional period unless you cancel. If you do not want to continue, cancel before the first billing date after the promotion ends, at least 24 hours ahead. Invite trials also renew automatically with the payment method on file.
A failed first payment does not mean you will not be charged; the billing system may retry later and succeed. If checkout showed $0.00 but you were still charged, contact support with screenshots and subscription details; refunds are handled case by case. See ChatGPT Plus vs Pro 100 for how Plus compares with other plans.

What happens if you cancel during a promotion? Can you get the offer back?
- You can cancel anytime, but on the platform where you subscribed: web subscriptions under Settings → Billing → Cancel on chatgpt.com, and App Store or Google Play subscriptions in that store. You cannot cancel a web subscription in the ChatGPT mobile app.
- If it was a free promotion, access may end as soon as you cancel; if it was a discount, you keep access for the rest of the current paid billing cycle.
- After you cancel, you cannot reuse the same promo code, and resubscribing does not restore the promotional price, even within the original promotional period.
- The promotion has to be used in consecutive months; you cannot pause it and continue later.

What does the 2026 Back to School student offer show about the rules?
This is a past example whose claim deadline has passed, used to show how OpenAI writes offer terms. The Help Center says the offer was for current full-time and part-time students at eligible US degree-granting institutions, verified through SheerID, with four free monthly Plus billing periods starting on the claim date. The claim deadline was October 31, 2026, and it could be redeemed once.
A valid payment method was required at activation, there was no charge during the free periods, and the subscription then renewed at $20 a month unless canceled. Subscriptions billed through the App Store or Google Play were not supported. If you canceled during the free months, Plus continued to the end of the current monthly billing period and the remaining promotional months were forfeited.

What falls outside the official rules?
The Help Center says promo codes must be used for their intended audience and purpose and may not be duplicated, sold or transferred. In cases of suspected misuse or fraud, OpenAI can revoke codes or end the service or account without a refund. Buying codes from others, passing them on, or stacking several codes therefore goes against the official terms. Compare regular subscription prices by region on ChatGPT prices.
