Master Street Address Guide (MSAG)

The MSAG is a database that houses all streets and addresses within the associated postal range for emergency service purposes. The MSAG directory for any address range belongs to the state or municipal authority.

Currently, 46 Labs partner with Bandwidth to provide Emergency Services.

Bandwidth utilizes MSAG when it comes to 911 access services. Bandwidth starts with your submitted civic/postal addresses, which they then geo-code to assign an X/Y coordinate for each record, providing confirmation upon successful validation. They then store the geo-coded address in the MSAG-compliant format for the jurisdiction in question. Each telephone number’s address is immediately available for PSAP queries. Bandwidth subscribes to the most current geo-code databases available and works with all 911 authorities to obtain MSAG and GIS files. Their dedicated support team, in turn, ensures timely updates to the validation engine.
