Switch, LATA and CLLI data
Look up number-related switch and geographic information for your communications workflows.

Put switch and location data to work
- LATA
- A Local Access and Transport Area identifier used in North American telecommunications.
- CLLI

- Rate center
- The geographic rating area associated with a telephone-number prefix.
- Switch and tandem
