# Running Out of Coupon Codes

If your promotion uses **single-use coupon codes** and your available codes are depleted, your Smart Funnel will automatically stop issuing coupons.

This ensures each customer receives a valid, unused code.

## **What Happens When Codes Run Out**

When your code pool reaches zero:

- Customers can still complete the funnel.
- No new coupon codes will be delivered.
- Redemptions requiring a code will remain pending until new codes are added.

To avoid interruptions, we recommend monitoring your available code count regularly.

## **How to Add More Coupon Codes**

You can add additional codes at any time:

1. Go to **[Promotions](https://reviewscango.com/home/promotions)** in your dashboard.
2. Select the promotion you want to update.
3. Locate the **Coupon Codes List** section.
4. Add new codes to the list (one per line).
5. Save your changes.

New codes become available immediately after saving.

## **Best Practice**

To prevent campaign disruption:

- [Upload codes in bulk](https://help.reviewscango.com/docs/how-to-bulk-upload-coupon-codes/) when possible.
- Keep a reserve of additional codes ready.
- Periodically check redemption volume during high-traffic campaigns.

If you anticipate large redemption volume, consider uploading a larger batch of codes in advance.
