# Using dedicated numbers with Notify
<a name="notify-dedicated-numbers"></a>

By default, Notify uses AWS-managed origination identities to send messages. You can optionally associate an existing phone pool with your Notify configuration to use your own dedicated phone numbers alongside AWS-managed identities.

**Note**  
For some countries, AWS does not provide managed origination identities. In these cases, you must associate your own phone pool with customer-owned numbers to send messages to those countries. Use the `ListNotifyCountries` API or the console Countries tab to check which countries require customer-owned identities.

## How hybrid routing works
<a name="notify-dedicated-numbers-routing"></a>

When you associate a phone pool with a Notify configuration, the system uses the following routing logic for each message:

1. Check the associated pool for a customer-owned origination identity that supports the destination country.

1. If a matching identity is found, use it to send the message.

1. If no matching identity is found (or no pool is associated), fall back to AWS-managed identities.

## Benefits of associating a pool

+ Use your own dedicated short codes or toll-free numbers for specific countries.
+ Existing opt-out lists on the pool are respected.
