# Series plates

> Assign permanent plate numbers across every event in a series.

A series **plate** is a number assigned to a rider for the entire season. When a race's bib source is set to `series` or `series_then_manual`, the rider's series plate is used as their bib on race day. See [Bibs](/organizers/events/bibs) for the source modes.

Manage plates at `/organizations/[id]/series/[seriesId]/plates`.

## Assign a plate

1. Click **Assign plate**.
2. Enter the **plate number**.
3. Search for the rider by name (filtered to participants who have registered for any event in the series).
4. Click **Assign**.

Each plate can be held by exactly one rider at a time, and each rider can hold exactly one plate per series.

## Search & filter

The search box filters the table by rider name or plate number.

## Release a plate

Click the trash icon on a row to **release** that plate. The rider's `seriesPlate` is cleared; the plate becomes available for reassignment. The release is timestamped on the audit log.

## Use across events

Once assigned, the rider's series plate auto-flows into any race that has `bibSource: series` or `series_then_manual`. No further per-event work needed — bib day-of, RFID lookups, and printable lists all use it.

## Filters and search

The table is paginated and supports:

* **Status** filter — `assigned`, `retired`, `conflict`, `reserved`, or `all`.
* A single **search box** that matches participant name **or** plate number (server-side, honoring the series' leading-zero rule).

## Auto-assign missing plates

Click **Auto-assign** to fill in plates for participants who don't have one yet. You enter a **starting number** and Time2Bike previews the full plan (every proposed `participant → plate`, plus any skipped rows with a reason) before anything is committed. **Reserved ranges** are skipped automatically.

## Reserved ranges

From **Reserved ranges**, define ranges of plate numbers you don't want assigned (e.g. `1–50` for pros, `100–199` for staff). Both auto-assign and manual assign refuse to use plates inside a reserved range with a clear error.

## Bulk import

Click **Import CSV** to upload a `plate,participantId` CSV. You'll see row-level results before anything is written:

* **Created** — new assignment.
* **Updated** — participant's existing assignment changed.
* **Skipped (conflict)** — that plate is already on another rider.
* **Error** — bad row; reason is shown.

## Merge participants

If the same rider has been registered twice (e.g. as two different participants), **Merge** consolidates their plate history onto a single participant. The operation is audit-logged and requires typed confirmation.

## History

Click the history icon on a row to see every change to that plate — who, when, before, after, and an optional note.

## Download CSV

**Download CSV** streams the current filtered view. Works for large series (500+ plates).
