Here is what I used 6 years ago to justify my AS #
Our network is multi-homed to two AS's that will not advertise our network
prefix with the network length associated with our external addressing. Only
our AS will advertise this prefix to the global internet. Our network policy
involves advertising 63.X.X.X/24 and 65.X.X.X/24 from behind AS 701 & AS
209. These networks only advertise 63.X.X.X/9 and 65.X.X.X/12.
The longer /24 prefix is required to influence inbound traffic flow and
redundancy.

Subject: Requesting an AS number
Hi all,
Does someone know to explain exactly what routing policy requirements is the
last option bellow:
When completing the template, your organization must first establish
justification for the request. Justification can be made by meeting at least
one of the following two requirements.
Multi-homed:
If your organization is multi-homed, or intends to be multi-homed within the
next thirty (30) days, you must show exactly how your organization is
connected to the Internet by providing the following information:
1. Exterior gateway protocol to be used
2. The IP network addresses presently in use on the network
3. The AS number and name of each upstream provider and/or peer
Unique Routing Policy:
*Your organization must demonstrate how the routing policy of the AS will
differ from the routing policies of its border peers*
Thanks,
Gabriel Nunes CCIE#17737
