# Deduplication

> Introduction to Deduplication

Converge supports deduplication natively. You can deduplicate events with an optional `eventID` parameter. This is especially important for events that are used as conversions. Converge will deduplicate events with the same `eventID` at ingestion time.

The `eventID` will also be forwarded to your destinations for in-platform deduplication.

### Limitations of deduplication

Converge only supports deduplication within a single data source, for now.
If you track the same event across multiple data sources, these won't be deduplicated.
