# Distribution & Access

> Learn how tickets reach customers through sales channels and partners, how they are delivered, transferred and resold, and how access control validates them at entry.

**Ticket distribution is how tickets reach buyers: through an organiser's own shop, a box office, partners and resale. Access control is how a ticket is checked when its holder arrives.** The two are connected, because every transfer, resale or reissue changes which ticket is valid and who holds it.

## Key ideas in this subject

#### Each sales channel needs rules about what it sells

Partners, promoters, affiliates and box offices may sell from shared or dedicated stock, in different windows and to different customer groups.

#### A ticket's life continues after purchase

Delivery, wallets, transfers, exchanges and resale all have to keep one record of which ticket is valid and who holds it.

#### Validation decides whether a ticket admits someone now

A scan checks the event, time, entrance and current status. Venues also plan for offline scanning, repeat use and restricted areas.

#### Transfers and resale follow the organiser's rules

Whether a ticket can be passed on, at what price and how its old barcode is invalidated varies by event and market.
