4. Why does the City need EAS?
Multiple address databases used by City Departments
Varying needs and uses
Varying formats
Varying quality
Addresses are critical
Current ad hoc situation leads to inefficiencies, confusion, lost time and effort.

5. EAS is … Focused solely on address management
Shared source of address information
Available across departments
Easy to use
To be integrated with DBI’s Address Verification System (AVS) and permitting system
