landlinecheck works by passively testing telecom networks and exchange equipment to rapidly detect the status of UK telephone lines (starting 01xxx, 02xxx). Our batch processing system can test thousands of number per hour, without denying a dial tone to subscribers at any stage. landlinecheck is fully compliant with Ofcom rules and regulations and adheres to all relevant DMA guidelines.

We take data security very seriously. All data is transferred over a secure connection (https). Clients are free to choose the data retention period (7, 14, 21 or 28 days) or can delete data instantly. The maximum data retention period is 28 days. Any data processed via the API is not stored.

landlinecheck supports Excel (xls, xlsx) and comma separated (csv, txt) formats.
