BGN Deprecation

On February 1, 2026, Bulgaria will change their official currency from BGN to EUR. In preparation, we will deprecate the BGN currency in Google Ad Manager on March 10, 2026.

What you need to do

The deprecation will be a multi-step process, some of which we will automate on your behalf. Below are step-by-step instructions to guide you through the process.

1. On January 8, we enabled EUR as a secondary currency in your network. This will enable you to start creating new orders, line items and deals in EUR ahead of the BGN deprecation. 
2. On March 10,  we will make the following updates to your network:
   1. Pause all BGN orders, line items and deals in your network. You won’t be able to restart these entities. 
   2. For active networks, create replacement Price Priority line items in EUR using the fixed exchange rate. The replacement line items will start on March 10 and keep the same end date as the original BGN line items. Any remaining impressions that have not yet been delivered will be carried over to the new line item. 
   3. Applies to AdX-enabled accounts only Update Pricing rules from BGN to EUR using the fixed exchange rate. 
   4. Perform a backend change to your network to change the default network currency from BGN to EUR.

How to recreate your orders

1. Copy the original order. Use the copy option which is best for you. “Copy order with creatives” and “Copy order and share creatives” do not require you to re-create the creatives. The new order will be in a Draft state.  
2. Do not approve the order until you update the line item’s currency. Currency can only be updated before a line item is activated. Approving could lead to activation based on your network’s settings.
3. Click all the line items you need to update in the copied order.
4. In "Delivery Settings", update the currency from BGN to EUR and adjust the rate as needed. You can use the next arrow to move between each line item in the order.
5. Click Approve to approve the order.
6. Click Activate for the selected line items that need to run when all line items have been updated. 

Important notes

• You will be able to continue using BGN for existing line items and deals up until the deprecation, but we strongly encourage you to update them ahead of the deadline.
• You will need to create new line items in EUR as it is not possible to change the currency on existing line items.
• Existing deals in BGN will need to be recreated in EUR. Any remaining deals after the conversion to EUR will be paused.
• Price Priority line items we create on your behalf that have a value of less than .01 EUR will be converted to .00 EUR.
• Applies to AdX-enabled accounts only Pricing Rules that have a floor or target CPM of less than .01 EUR after conversion will be deactivated.
• Reports that only include dates before the deprecation will remain in BGN. Reports that include dates after the deprecation will be in EUR. Any report that spans both date ranges will throw an error. 
• When we change the network currency to EUR, reporting in your network might reflect some inaccurate pricing data. This will only exist for the small cutover window while settings take effect.

Please be sure to visit the help center for helpful information regarding currency settings and review the above instructions carefully in order to take the necessary actions in your network to prepare for the upcoming deprecation.
