HLR Number Lookups
Use our online tool.
Use our network lookup service for data cleansing and phone network identification. You can identify the state (active/non-active) and network operator for UK mobile or landline numbers based on Ofcom information. This can help prevent you from sending messages to numbers which are no longer online.
To perform a genuine (live) network lookup or a network lookup on foreign (non-UK) telephone number, you'll need to log in to the aql portal. Each genuine network lookup costs one SMS credit.
