What is OpenCellID?

OpenCellID is the world's largest collaborative community project that collects GPS positions of cell towers, used free of charge, for a multitude of commercial and private purposes.

More than 49,000 contributors have already registered with OpenCellID, contributing more than 1 million new measurements every day in average to the OpenCellID database. Detailed statistics are available in real time.

The OpenCellID project was primarily created to serve as a data source for GSM localisation.
As of Jan, 2015, the database contained almost 7 million unique GSM Cell IDs and 1.2 Billion measurements.

OpenCellID provides 100% free Cell ID data (CC-BY-SA 3.0 license).
The OpenCellID database is published under a Creative Commons open content license with the intention of promoting free use and redistribution of the data.

All data uploaded by any of the contributors can also be downloaded again free of charge - no exceptions!
