Every time Telebase receives a query, we return up to six signals from the carrier network.
Each signal is sourced in real time — not from a static database — and returned in a single normalised JSON response in under 500ms.
Is this number active or disconnected right now — queried directly from carrier networks, not a static database. The most fundamental check before any transaction.
Which network owns the number, which country it's registered in, and whether it matches the user's stated location. Flag mismatches instantly.
SIM swap history
Was this SIM changed in the last 24, 48, or 72 hours? The single most reliable signal for account takeover fraud. A SIM swap before a wire transfer is a major red flag.
Roaming status
Is the device currently on a foreign network? Roaming during a domestic transaction is an anomaly worth flagging — particularly for high-value transfers.
Audit log
Every query is logged with agent identity, timestamp, result, and cost. GDPR-aware from day one. Full audit trail for compliance and dispute resolution.
