# Configuration profiles

Configuration Profiles apply reusable DID number settings in one action. Use this section to understand how profiles and
rules work, create reusable configurations, and apply voice, SMS, capacity, and description settings consistently.

## Key features

- Reuse the same voice, SMS, Capacity, and description settings across multiple DID numbers.
- Apply a saved configuration to existing DID numbers in one step.
- Automatically apply the right configuration to newly purchased DID numbers.
- Choose where a rule applies by country, number type, region, or city.
- Keep DID number setup consistent without re-entering the same details.
- Control which configuration is applied to new numbers as they are purchased.
