# Bibs

> Assign plate numbers to registrants.

**Event → Bibs** is the bib (plate) manager. Each row is a registration; the **Bib number** column is the plate assigned to that rider for that race.

## Bib source per race

Each race has a **bib source** that controls where the rider's plate comes from on race day:

* **Manual only** — use the plate assigned in this event (race or event scope).
* **Series only** — use the plate from the series the race belongs to (see [Series plates](/organizers/series/series-plates)).
* **Manual, fall back to series** — prefer the race/event plate; if none, use the series plate.

Change the source from the **Race source** dropdown above each race's rows.

## Auto-assign

Click **Auto-assign**. You choose:

* **Start number** — first plate to hand out (default `1`).
* **Race scope** — apply to a specific race, or to all races in the event.
* **Assignment scope** — `event` (one plate per rider across all their races) or `race` (separate plate per race entry).
* **Method** — `sequential` or `random`.

The action only fills empty slots; existing assignments are preserved. Run it again after late registrations to top up.

## Manual assign

Click a row's plate cell to enter or edit a number by hand. You'll also pick the scope (`event` or `race`).

## Export

**Download CSV** exports the current bib list with participant name, race, category, and plate.

## Plate requests

Riders who paid the **replacement plate fee** during registration appear here as **plate requests** — yellow rows flagged **Needs new plate**. Filter the page with **Plate request: has request** to see only those rows.

Click the row to assign a new number; the request transitions to **New plate assigned** and the new plate propagates to the series if the race is series-scoped. See [New-plate requests](/organizers/events/plate-requests) for the full workflow, including refunds.

## Transponders

For RFID-timed events, each rider's plate also needs a chip mapping. Use the [Transponders](/organizers/events/transponders) page next to **Bibs** to manage chip-to-participant assignments.
