If you're in an area with jurisdictions that are unclear, this database is a good reference. The only problem is, there are no phone #'s!
"PSAP Registry: In December 2003, the FCC began collecting data to build a registry of public safety answering points (PSAPs). A primary PSAP is defined as a PSAP to which 9-1-1 calls are routed directly from the 9-1-1 Control Office, such as, a selective router or 9-1-1 tandem. A secondary PSAP is defined as a PSAP to which 9-1-1 calls are transferred from a primary PSAP. The PSAP database serves as a tool to aid the Commission in evaluating the state of PSAP readiness and E9-1-1 deployment."
