What is a DID Number?

A DID Number (Direct Inward Dialing number) is a virtual phone number that allows businesses to receive incoming calls without being tied to a physical phone line or location. Instead of connecting to a specific handset, a DID number routes calls over IP networks to any predefined destination such as a VoIP phone, SIP trunk, PBX system, mobile device, or cloud contact center. This makes DID numbers ideal for businesses that need flexibility, scalability, and a local presence across multiple regions.

DID numbers enable companies to establish local, national, toll-free, or international calling presence without setting up offices in each location.

How a DID Number Works?

When someone calls a DID number, the call is received by the provider’s network and instantly forwarded to the destination set by the business, such as a call center, IVR, or remote team. Because the number is virtual, call routing can be easily changed, scaled, or optimized without physical infrastructure, ensuring reliable and efficient inbound call handling.

Frequently Asked Questions

Can’t find the answer that you are looking for? Feel free to contact us.

What are DID (Virtual) Numbers?

DID (Direct Inward Dialing) numbers, also called virtual numbers, are telephone numbers not tied to a physical line. Instead of connecting to a dedicated phone line, a DID number forwards incoming calls to a phone, VoIP line, or PBX of your choice. This allows businesses to have a local or toll-free presence in multiple cities or countries without maintaining physical offices or infrastructure in each location.

What types of DID Numbers does IDT Express offer?

IDT Express offers local (city), national, and toll-free numbers across a broad selection of countries. These numbers enable businesses to manage inbound campaigns, provide a local presence, and scale operations globally without geographic constraints.

Why should a business use DID Numbers?

Using DID numbers allows businesses to appear local to customers in different regions, enhancing trust and accessibility. Call centers, cloud PBX/UCaaS/CPaaS providers, and enterprises operating globally benefit from flexible inbound call handling, improved customer experience, and efficient management of communications. Businesses can route calls to any destination, monitor performance, and adapt to changing call volumes in real time.

How do I get started with IDT Express DID Numbers?

Businesses can start by submitting their company details through the sign-up form. New customers often receive a trial credit to test the service. An account manager guides you through provisioning numbers, selecting area codes or countries, and configuring routing to meet your requirements. This ensures you can quickly test the numbers and integrate them with your existing infrastructure.

Can I manage DID Numbers myself — provision, porting, and configuration?

Yes. IDT Express offers a self-service portal where you can browse available numbers, provision new DIDs, and manage number configurations. Advanced users can also leverage APIs for automated provisioning or bulk management. Porting is supported where local regulations allow, letting customers bring numbers in or take them out of the platform when permitted.

What compliance and KYC requirements are involved?

To comply with local and international regulations, IDT Express requires customers to complete Know Your Customer (KYC) verification before provisioning numbers. This typically involves submitting company registration documents, proof of address, and authorized contact information. Compliance ensures that numbers are used lawfully, prevents fraud, and aligns with telecommunication regulations in each country where the numbers are allocated. Some countries may have additional requirements for toll-free, mobile, or special-rate numbers, which IDT Express will guide you through during onboarding.

What are the billing and service terms for DID Numbers?

DID numbers include setup charges, monthly recurring fees, and, if applicable, usage-based charges for forwarded calls. The minimum service term is one month, with automatic monthly renewal until cancellation. Fees are charged in advance, and prorated charges apply for mid-month cancellations. Customers can manage their usage and optimize costs through the self-service portal.

Which types of businesses or use-cases are a good fit for IDT Express DID Numbers?

IDT Express DID Numbers are ideal for call centers, cloud PBX/UCaaS/CPaaS providers, SaaS platforms needing a local phone presence, wholesale VoIP/DID resellers, and any business that wants a global presence without physical offices. These numbers allow enterprises to centralize call handling while maintaining local accessibility, improving both operational efficiency and customer engagement.

What support and infrastructure backs IDT Express DID Numbers?

DID numbers are provisioned via licensed operators, ensuring compliance and reliability. IDT Express offers a fully redundant global network and 24/7 customer support, including account management and technical assistance. This infrastructure ensures scalability, high availability, and smooth handling of high call volumes across multiple geographies.

Are there limitations or restrictions on using DID Numbers?

DID numbers are allocated for use during the service term and are subject to availability. Certain regulatory restrictions apply depending on the country, such as porting limitations or restrictions on forwarding or usage. Compliance with KYC requirements is mandatory, and numbers must be used in accordance with telecommunication laws in each jurisdiction.
