You can change the currency that you use for Facebook ads once every 60 days if you don't have a current balance.

Before you begin

Here are some things to bear in mind about changing your currency:

• When you choose a new currency and time zone, you'll create a new ad account. Your old ad account will be visible in the Account drop-down in the top-left of your Ads Manager, but it will be closed and all ads created with your old account will stop running. Any ads that you had running on the old ad account will be billed in the old currency.
• The payment methods available to you depend on the currency you choose.
• For some countries (like Brazil, Nigeria and Venezuela), your ad account's business country and currency must match.
• If you select a country other than Brazil when you create your ad account, you won't be able to change your country to Brazil later. In addition, if you select a currency other than BRL when you create your ad account, you won't be able to change it to BRL later.

Steps to change the currency that you use for Facebook ads

1. Go to Ad account settings in Ads Manager.
2. Under Currency, click Change Currency.
3. Select your new currency and time zone, then click Create New Account.

Why can't I change the currency of my ad account?

If you've followed these steps and you're unable to change your currency, there may be a few reasons why this option isn't appearing:

• Your account is unsettled.
• You have ads pending review.
• You've already changed your currency twice in the past 28 days.
• You're looking at an account other than your personal ad account.
• If you're using Business Manager and your account has several other accounts associated with it, it isn't possible to change your currency. You'll need to create a new account from Business Manager with the new currency.
