Number Lookup · HLR · MNP · Portability

Number lookup tells a carrier or aggregator, before sending, which operator really owns a phone number and whether it can be reached, including numbers that have been ported. BroadNet Number Lookup draws on live HLR/HSS, MNP and number-portability data across 200+ countries.

HLR, MNP, and portability — across 200+ countries, in milliseconds.

Routing on prefix tables is how operators lose money. BroadNet Number Lookup queries live HLR/HSS, MNP databases, and number-portability registries — so every dial is sent to the real owning carrier, billed at the right rate, and reachable. Cached intelligently. Refreshed on activity. Exposed over REST, SS7, and SMPP.

Capabilities

## Routing truth in a single call.

HLR, MNP, ported-out flags, IMSI, and serving-network identity — collapsed into one normalised response. Use it to clean lists, route messages, and detect SIM swap.

### Live HLR / HSS

Real-time MAP SRI-SM and S6a queries against the destination HLR/HSS. Returns serving MCC/MNC, IMSI, and roaming status.

MAP SRI-SM S6a Roaming status

### MNP & portability

Lookup against national MNP databases — Reliance Jio, OPTA, BIPT, US NPAC, plus 90+ other regulators. Catch ported numbers before you dial the wrong carrier.

NPAC OPTA / BIPT 90+ MNPs

### Intelligent caching

Per-range TTL based on observed churn. Hot numbers refreshed on activity; cold ranges cached for longer. Reduces operator HLR query load.

Adaptive TTL Cache-first Per-MNC tuning

### SIM swap detection

Track changes in serving IMSI, MCC/MNC, and last-update timestamp — signal to banks, OTP providers, and risk engines before authorising sensitive actions.

### REST · SMPP · SS7

Bind however your stack prefers. JSON over HTTPS for product teams; SMPP USSDN for SMSC plug-in; raw SS7 MAP for carrier gateways.

### Privacy & residency

MSISDNs hashed at rest. Per-tenant key isolation. EU, GCC, and APAC data-residency options for regulated workloads.

Why operators run it inline

## Cleaner routes. Lower HLR load. Fewer disputes.

Number lookup pays for itself the first time you stop routing A2P to a long-ported range. Run it as a pre-filter to your SMSC and watch dispute volume drop overnight.
