About CELLID

What is CELLID?

The world's largest open database of cell towers

A community-built dataset of cellular network observations. Explore cells across GSM, CDMA, UMTS, LTE and 5G NR, look up their locations, and build with the data.

Started in 2008 and maintained by Undfe since 2017, CELLID brings contributors, researchers and developers together around open cellular data.

55M+cells recorded

200+countries & territories

10K+contributors

Since 2008community-powered

How CELLID works

Contributors collect observations

People use apps and devices to record nearby cell identifiers alongside their GPS location, then share those observations with CELLID.

Observations become estimates

CELLID processes the measurements to estimate cell locations. New observations add missing cells and refine existing estimates.

Apps put the data to work

Apps look up the cells a device can detect. Those estimated cell locations can help locate the device when GPS is unavailable.

For developers & researchers

Build with CELLID

Use cellular data in your apps, research and network analysis. Query individual cells or work with the dataset in your own tools.
