Wholesale Toll-Free Numbers
Horizon Communications Group is a wholesale toll-free number provider for carriers, CLECs, CPaaS and UCaaS platforms, and resellers. Founder-led since 1998, we provision toll-free numbers across the available prefixes, coordinate ports of existing numbers, and route inbound calls to your platform.
What are wholesale toll-free numbers?
A toll-free number is one a caller can dial at no charge, with the cost borne by the receiving party or their provider. Toll-free numbers use the 800, 888, 877, 866, 855, 844, and 833 prefixes and reach the called party nationwide rather than tying to a single area.
Wholesale toll-free means provisioning and porting these numbers in volume for providers. Toll-free numbers pair naturally withlocal DID numbersfor a full inbound footprint, and inbound calls reach you throughorigination.
Available toll-free prefixes
Toll-free numbers are provisioned across all seven active prefixes. Availability of a specific number varies, so the desk checks what is open for the patterns you want.

Toll-free numbers FAQ
How do toll-free numbers work for carriers?
A toll-free number routes inbound calls to the called party at no charge to the caller; the receiving party or their provider bears the cost of the call. For carriers and providers, you assign toll-free numbers to customers and deliver the inbound calls over your network through origination. Wholesale toll-free lets you offer that service without managing every piece yourself.
What toll-free prefixes are available?
Toll-free numbers use the 800, 888, 877, 866, 855, 844, and 833 prefixes. Availability of a specific number varies across those prefixes, so the desk checks what is currently available for the numbers or patterns you want and provisions from there.
Can I port existing toll-free numbers?
Yes. Existing toll-free numbers can be ported between providers through the toll-free administration process. Horizon coordinates the port so your numbers keep working while they move, then sets inbound routing so calls land on your platform.
Need a wholesale toll-free number provider?
