Audience Manager sets a maximum limit on the number of traits, segments, destinations, and algorithmic models that you can create for an account. Limits apply to these items whether created in the user interface or programmatically through API methods. Usage limits help protect Audience Manager from automated processes that may attempt to compromise our APIs or user interface.
ID Mapping Limits
The table below lists the ID mapping limits for device IDs. Once an ID reaches any of the limits below, Audience Manager adds new ID mappings based on a FIFO (first in, first out) logic, by removing the oldest stored ID mapping, and adding the new one. Refer to Index of IDs in Audience Manager for details on the IDs supported by Audience Manager.
Cookie/browser ID to cookie/browser ID
1000 cookie/browser IDs to 1 cookie/browser ID
The tables list the current limits by item type. You cannot create new traits, segments, destinations, or Algorithmic Models if you reach a specific limit for one of these items. If you do reach a limit, you must delete an older item before you can create a new one.
