Every kind of number, in every market
Whatever presence you need — a local footprint, a country-wide line, a mobile number for SMS, or a toll-free line — Callr provisions it in standard E.164 format, ready to use.
Local & geographic
Give customers a familiar number in their own city or region — local presence lifts answer rates.
National
A single country-wide, non-geographic number that isn’t tied to any one area code.
Mobile
Mobile numbers for two-way SMS and voice, for reaching people where a mobile line matters most.
Toll-free
Free-to-caller numbers that signal an established, trustworthy business your customers can reach at no cost.
Coverage
Numbers everywhere, on a network we own
Callr is a registered carrier running its own encrypted network across 220+ countries — so you provision numbers directly from us, not through a chain of resellers.

A few of the markets we cover
One number, the whole platform
A number is where it starts — not where it ends
Point a Callr number at your business and it inherits everything the platform does. No add-ons, no separate products — data, insights, and AI come with the number.
Programmable call flows
Attach a Callr Actions scenario to any number — IVR, business hours, failover, whisper, click-to-call — changed in YAML, not in hardware.
AI on every call
Record, transcribe, and run sentiment analysis, entity and keyword extraction, or a full AI voice agent on the calls hitting your number.
Real-time data & insights
Every call writes a detailed record you can pull from the REST API or receive as webhooks the moment it happens — straight into your CRM and BI.
Voice and SMS in one
The same number handles calls and two-way SMS, so a conversation can move between channels without a second provider.
Use cases
Where a Callr number goes to work
The same number, pointed at different jobs across your stack.
