Informational Services & APIs
Simple solutions for complex problems
The best routing decisions start with the best data. Tychron's informational APIs tell you who operates a number, where it lives, and whether it can receive your message — in real time, per query or in bulk — so every call and text takes the smartest path.
Understand and take control of your network with powerful APIs
Location Routing Number (LRN) & eLRN Lookup
Access a number's geographical and carrier details via HTTP.
The LRN is how the network knows where a ported number really lives. Tychron's enhanced LRN (eLRN) lookup returns the routing and carrier detail behind any number, including:
- State, City, ZIP, and Timezone
- Rate Center, Local Access and Transport Area, and Operating Company Number
- LRN, Carrier, and Carrier Type
*Available data varies based on service area.
Route calls on where numbers actually terminate — not where their area code suggests — for fewer dropped connections and lower costs. With Tychron, the control is all yours.
Caller ID Name (CNAM) Lookup w/ Robocall Status
Identify callers — and spot robocalls — via HTTP.
CNAM is the caller ID name registry behind "who's calling" — and Tychron's CNAM API adds robocall status, included free. Display real caller names, flag likely spam before the phone rings, and give every answered call a fighting chance. It's easy to get the upper hand on spoofers with Tychron.
Messaging Carrier Lookup (MCL)
Know a number's messaging carrier before you send.
MCL tells you which network serves a number and whether it's text-enabled — so you skip undeliverable sends, avoid unnecessary carrier surcharges, and plan campaigns against real per-carrier volumes. Run it per message or as bulk lookups with results delivered to your webhook. Get the most out of your messaging with Tychron.
For developers & platforms
One lookup or a million — same API
Every lookup runs per query over HTTP, or as bulk dip tasks that work through whole number files and deliver the results straight to your webhook — including enriched fields like enhanced country codes and LRN activation timestamps. The complete Atlas API & Provisioning Reference documents every endpoint, schema, and webhook payload.
