# Settings: Person Matches

> Cached external-reference to Planning Center person mappings

Person Matches shows cached mappings Port uses during person matching.

## What Is Cached

A row links:

* External reference ID
* Planning Center person ID
* Person name
* Last update time

These references are reused across imports to avoid re-matching the same source reference every time.

## Delete Behavior

Delete is executed by `personID` for your organization.

That means removing a row clears cached matching for that person ID in your org, and future imports for those references must be matched again.

## When to Delete a Match

* A source reference was matched to the wrong person
* A person merge/restructure in Planning Center requires rematching
* You need Port to re-run matching logic on next import
