e164 Information

e164 provides global telephone numbering data for telecom operators, carriers, routing teams, fraud teams and developers. Covering numbering plans around the world, e164 helps organisations understand which number ranges exist, how they are structured, who they are allocated to and when those allocations change. Our numbering data is continually updated as regulators publish new allocations, operators move, companies merge and ranges are withdrawn. We track thousands of changes across global numbering plans so telecom teams do not have to rely on static files or fragmented regulator sources. e164 also works closely with the ITU and the wider numbering community, contributing to discussions around numbering transparency, data quality and how global numbering information can be improved. e164 is used for routing, CLI validation, fraud prevention, billing, number validation and other workflows where accurate numbering data matters. Alongside the full dataset, e164 also provides free tools for prefix searches, operator and regulator research and MCC/MNC lookup. e164 is part of Acudo, alongside HLR Lookup and TPS Unlimited, bringing together specialist services across numbering data, mobile number intelligence and outbound communications compliance.
