An agency is using labels to organize their brand campaigns across a sub-manager account. What's the maximum number of labels an advertiser can have across their entire Search Ads 360 account?

Search Ads 360 applies an account-wide limit to labels , so the cap is measured across the advertiser’s full account rather than by campaign, ad group, or keyword. Google’s label documentation states that advertisers are limited to 1,000 labels across their entire account. This makes the limit a platform rule for total label inventory, which is why agencies must manage label taxonomy carefully when organizing campaigns at scale. The key distinction is that the ceiling applies to all labels in the account, not only to labels currently assigned to active entities. Google Help
