# Recipient routing
> Control signing order with sequential or parallel recipient routing options
The `routing` property controls the order in which recipients receive and act on the envelope. Two options are available: `sequential` and `parallel`. The default is `sequential`.
## Sequential routing
With sequential routing, the envelope is delivered to one recipient at a time, in the order listed in the `recipients` array. Each recipient must complete their part before the next one is notified.
* Recipients act in the order defined in the `recipients` array.
* Each recipient must complete before the next one is notified.
* Recipients acting later can see signatures and data entered by those who acted before them.
* Recipients waiting for a previous recipient will have a status of `awaiting`.
* Use this when the order of signatures matters.
## Parallel routing
With parallel routing, all recipients receive the envelope at the same time and can act in any order.
* All recipients are notified simultaneously.
* Recipients can act in any order.
* Use this when signing order does not matter.
## Setting routing on an envelope
Set the `routing` property when creating an envelope. If omitted, sequential routing is used.
