Short answer: DID numbers route calls directly to your business system. Local phone numbers create local presence in a city or region. Toll free numbers let customers call without paying for the call in supported markets. Many businesses use all three for different customer journeys.
What Is a DID Number?
DID stands for Direct Inward Dialing. A DID number is a phone number that routes inbound calls directly to a destination such as an IVR, queue, agent, SIP address, or cloud phone system.
What Is a Local Phone Number?
A local phone number uses a city or regional area code. It helps businesses look familiar to customers in a specific market. Local numbers are often DID numbers, but the term "local" describes the geographic presence.
What Is a Toll-Free Number?
A toll-free number lets customers call without paying the standard call charge, depending on the country and network. The business pays for inbound usage. Toll-free numbers are useful for support, sales, trust, and national campaigns.
