# Authorize ASN

Autonomous System Number (ASN) is a unique identifier assigned to an autonomous system (AS) on the internet. ASNs are crucial for the functioning of our global BGP. You can submit a request for your own AS authorization to establish global BGP Interconnect.

## Procedures

Submit a request for your own AS authorization to establish global BGP interconnect.
