NPA NXX Database with Rate Center and Operating Company Number

This NPA NXX database version adds unique, clean, manually verified Rate Center Names and Operating Company Number to our standard Area Code Database. This intuitive element is incredibly helpful for reporting (such as a Call Accounting Software report) or for it to appear in the Caller ID of a telephony application. Telecom industry rate center names are heavily abbreviated such as: “NWYRCYZN01” (our version is: New York City Zone 1).

This NPA NXX Database product is updated regularly as area code time zone data is added and is released monthly. The price includes an initial download and any updates made available throughout your subscription period.
