Work with duplicate labels

When using the Standard Label Engine to label line and polygon layers, you can choose one of the following three options for handling duplicate labels.


There are no duplicate label options when labeling point features.

  • Remove all duplicates—This is the default when labeling line features. When two or more contiguous line features have the same label text string, only one label is placed. When labeling polygon features, only one label is placed; the features need not be contiguous. This prevents displaying potentially many of the same labels on your map.
  • One label per feature—A label is placed for every feature. Duplicate labels are not removed. If you have a multipart feature, this option places one label for the entire multipart polygon.
  • One label per part—This is the default when labeling polygon features. A label is placed for each part of a multipart feature. Duplicates are not removed.

If you enable the Maplex Label Engine, you will see different options for working with duplicate labels.
