A Direct Inward Dialing (DID) number is a virtual phone number that routes calls and messages directly to your application, call center, or communication platform without requiring a physical phone line. DID numbers give your business a local presence in any city or region across the US and Canada.
With AHOI, you can search and provision DID numbers instantly via API or our web portal. Each number supports voice calls, SMS, MMS, and fax, and can be configured with call forwarding, IVR, webhooks, and programmable routing rules — all managed through a single dashboard.
AHOI manages the underlying carrier infrastructure, number inventory, regulatory compliance, and CNAM registration so you can focus on building your product rather than managing telecom operations.
