DUPLICATE_CAMPAIGN_NAME (Google Ads)

Why Google refuses a launch with DUPLICATE_CAMPAIGN_NAME when a campaign with the same name already exists in the account, why AdWhispr never renames it for you, and how to resume the existing campaign or relaunch under a new name.

Whose side it is on
The campaign name in your launch, or an earlier launch that already exists.
What you see
DUPLICATE_CAMPAIGN_NAME: Campaign with this name already exists in this account.

What this error means

Google does not allow two active or paused campaigns with the same name in one account, and one with this name already exists. Often it was created by an earlier attempt: a launch that stopped at a policy rejection, or one you ran twice. The chat checks for this before creating anything, so this error is now rare.

Whose side it is on

Yours: the name, or an existing campaign you may have forgotten.

How to fix it

  1. Ask the chat to list the campaigns in the account and find the one with this name.
  2. If it is the campaign you wanted, resume or edit that one instead of creating another.
  3. If you really want a second campaign, launch again under a different name.

AdWhispr never renames a launch automatically. When you relaunch a live campaign by mistake, this block is what stops a silent duplicate and double spend.

Relaunch

Run the launch with the new name, or resume the existing campaign.

Frequently asked questions

Why does the existing campaign have no ads?

A launch that failed part way (for example at a policy rejection) can leave a campaign shell. Since 2026-08-28 such shells are rolled back automatically. For an older one, edit it in Google Ads or launch under a new name.
