# E04031 — ContactPropertyLimit

This workspace has reached the maximum number of contact properties. Archived properties still count toward this limit, so archiving does not free a slot; reuse or update an existing property instead.

- **HTTP status**: `422`
- **Type**: `validation_error`
- **Name**: `ContactPropertyLimit`

## What to do

The workspace is at its contact-property limit, and archiving one does not free a slot. Find an existing property that fits and update it instead of creating another.

Operations that resolve this:

- [List contact properties](/docs/api/reference/list-contact-properties)
- [Update a contact property](/docs/api/reference/update-contact-property)
