Global Numbers provisioning
Provision phone numbers in 80+ countries instantly via the Portal or REST API. Geographic, toll-free, and mobile number types. Each number is assignable to a Callr Actions scenario for programmable call handling.
Overview
As a registered carrier with direct interconnections to local operators worldwide, Callr offers instant phone number provisioning in 80+ countries. Numbers are available in geographic (local), toll-free, and mobile formats depending on country regulations.
Provisioning Methods
Via the Callr Portal: browse available numbers by country and type, purchase with one click, and assign to a scenario. Via the REST API: automate number provisioning programmatically for large-scale deployments. Both methods activate numbers in seconds.
Number Management
Each number can be assigned to a Callr Actions scenario that defines how inbound calls are handled. Reassign numbers between scenarios at any time. Port existing numbers to Callr from other providers. Release numbers when no longer needed.
Regulatory Compliance
Callr handles local numbering regulations automatically. When country regulations require address verification or identity documentation, the process is managed within the Portal. We maintain compliance with local telecom authorities in every country we operate.
