# Why Was My TikTok Ad Credit Promo Code Rejected?

A rejected TikTok ad credit promo code means the code you entered did not pass TikTok’s validation check at the time of entry. This can happen for a range of reasons, most of which are fixable. Before concluding the code is invalid, verify the entry and the conditions attached to it.

## Most Common Reasons a Promo Code Is Rejected

| Reason | What to Check |
| --- | --- |
| Typing error | Codes are case-sensitive and must be entered exactly as issued, including any hyphens or underscores |
| Code already used | Most TikTok promo codes are single-use per account; entering a used code returns a rejection |
| Code expired | Each code has a defined validity window; codes entered after expiry are rejected automatically |
| Account ineligible | The code may be restricted to new advertisers, specific regions, or specific account types |
| Incorrect account type | A code issued for a self-serve account cannot be applied to a managed or agency account, and vice versa |
| Code obtained from an unofficial source | Codes shared on third-party sites, forums, or social media may be expired, fake, or already claimed |
| Market restriction | The code was issued for a specific country and your account is registered in a different market |

For the eligibility criteria that apply to [TikTok ad credit programs](https://getadcredit.com/visit/tiktok-ad-credit) more broadly, including new advertiser requirements, see [how TikTok ad credit works](https://getadcredit.com/question/how-does-tiktok-ad-credit-work/).

## How to Verify the Code Before Contacting Support

- Copy and paste the code directly from the original source rather than typing it manually.
- Check whether the code came from an official TikTok channel: your registered email, a TikTok partner, or your Ads Manager notifications.
- Confirm the code’s validity date has not passed by reviewing the original communication that included the code.
- Verify your account matches the eligibility criteria stated in the offer terms.

The terms governing TikTok promo codes and credit offers are published at [ads.tiktok.com/help/article/tiktok-coupon-terms](https://ads.tiktok.com/help/article/tiktok-coupon-terms). Reviewing those terms against your account situation will clarify most rejection cases.

## If the Code Should Be Valid

If you have confirmed the code is correct, unexpired, and your account is eligible, contact TikTok Ads support with the code, your account ID, and documentation of how you obtained the code. See how to contact TikTok Ads support for an ad credit issue, and how to submit an effective request.

## Frequently Asked Questions

### Can I use the same promo code on multiple TikTok accounts?

No. TikTok promo codes are issued on a single-use or single-account basis. Once a code is applied to one account, it cannot be applied to another. Codes tied to a new advertiser program are specifically validated against the account that received them and cannot be transferred or shared. Attempting to use a code on an account it was not issued to will result in rejection.

### Are TikTok promo codes shared on websites like Reddit or coupon sites legitimate?

Codes shared on third-party platforms are frequently expired, region-locked to a market other than yours, or already fully claimed. TikTok distributes promo codes directly to eligible advertisers through their registered email and Ads Manager, and through official TikTok for Business partners. Codes from unofficial sources carry a high risk of rejection and may also come with account risk if they originate from fraudulent promotions.

### Can a rejected code be reactivated by TikTok?

TikTok does not routinely reactivate expired or invalidated promo codes for individual advertisers. If a code was rejected due to a platform error rather than an eligibility issue, TikTok support may be able to investigate and issue a replacement. This requires contacting support with evidence that the code was valid and that the rejection was not due to ineligibility on your account.

### What is the difference between a promo code rejection and a credit application denial?

A promo code rejection is an immediate response when you enter a code in Ads Manager that does not pass validation. A credit application denial is a broader determination that your account does not qualify for a new advertiser credit program. Both result in no credit being applied, but the causes and remedies differ.
