HLR Query Service

Mobile Number Portability

With most countries now offering number portability, it's important not to route based on just the number prefix, but to perform a realtime HLR query. This can tell you the current serving network operator for any given mobile number.

HLR Query

Querying the number with the Home Location Register of the carrier confirms that the number is active, and served by that carrier. If the number has been ported, a flag points to the new operator.

Number Portability Lookup

We provide an HLR Query service, via its own site, at NumberPortabilityLookup.com for anyone needing this service.
