Can I use multiple promotional credits for Facebook Ads?

Yes, you can use multiple promotional credits for Facebook Ads, but there are some important conditions to keep in mind:

1. One Promo Code Per Campaign
Typically, Facebook allows you to use one promo code per campaign or ad account. If you have multiple promo codes, you may be able to apply them across different campaigns or accounts, but you cannot stack them within a single campaign.

2. Limit on Promo Code Use
Facebook may place limitations on how many promo codes can be used in total on an account, or how often they can be redeemed. Make sure you're not exceeding the redemption limits for your account.

3. Terms and Conditions
Different promo codes may have different terms and conditions. Some may be restricted to new advertisers or certain types of campaigns, while others may require specific spending thresholds to activate. Ensure that each promo code's terms align with your account's activity.

4. Regional and Account Restrictions
Promo codes may be restricted by region or account type (for example, they may only be available to certain countries or new advertisers). Ensure that each promo code you have is eligible for your specific account.

5. Promo Code Stacking Across Different Accounts
If you manage multiple ad accounts (such as for different businesses), you might be able to use promo codes on different accounts. Facebook generally allows each ad account to apply its own promo code, but again, check each code's eligibility.

6. Maximum Discount
Facebook may set a maximum limit on how much credit or discount can be applied via promo codes. Even if you use multiple codes, you may be capped at a certain discount or credit amount.

7. Payment Method
Make sure your payment method is correctly linked and updated. Sometimes, promo codes may fail to apply if there are issues with your payment method or billing information.

In summary:
You can use multiple promotional credits, but usually one per ad campaign or ad account.

Ensure eligibility for each code and follow its specific rules.
