The largest telecom aggregator in the U.S. — one bill, one team, every carrier nationwide
Granite Telecommunications is the largest privately held telecommunications company in the United States — built specifically to serve multi-location businesses that are tired of managing a patchwork of regional ISP relationships. Granite aggregates 300+ carriers and delivers everything from basic broadband to dedicated fiber internet and UCaaS under a single master agreement. For organizations with 25 to 25,000 locations spread across the country, Granite turns telecommunications management from a part-time IT job into a strategic asset.
Granite Telecommunications (Quincy, MA) is the largest privately held telecommunications company in the United States, serving over 650,000 locations for more than 85,000 business customers. Founded in 2002, Granite built its model on aggressive bulk purchasing from 300+ underlying carriers — negotiating rates that individual businesses cannot achieve — and delivering those services under a single Granite contract, bill, and SLA. Granite's portfolio spans broadband internet, dedicated fiber internet, Ethernet private lines, MPLS, hosted voice, UCaaS, and toll-free services. Their Granite Dedicated Access (GDA) service delivers managed fiber to enterprise locations, and their managed services layer includes 24/7 NOC monitoring, a U.S.-based customer support team, and proactive outage management.
Deployment model: Aggregated 300+ carriers + Granite-owned fiber (GDA); national; 650,000+ locations served. Pricing model: Per-location MRC; master service agreement; volume-based discounts. Typical price range: Competitive with carrier-direct; management and aggregation value included; custom enterprise quotes. Pricing is negotiable at volume — Compare Select benchmarks quotes against real transacted deals before you sign.
Granite contracts with 300+ underlying carriers — more than any other aggregator — delivering coverage to virtually any commercial address in the United States under a single contract.
One contract, one bill, one SLA for your entire location estate. Granite's legal and procurement team manages carrier terms on your behalf — you never negotiate with carriers directly.
Granite-owned dedicated fiber internet for enterprise locations — symmetrical speeds with 99.99% uptime SLA and four-hour resolution commitment. Granite's own infrastructure, not resold.
Granite's U.S.-based NOC monitors all circuits 24/7 and proactively addresses outages. Every customer has a dedicated account team — not a tier-one call center.
Granite's hosted voice and UCaaS replace on-prem PBX and traditional POTS lines — delivered over the same Granite network, simplifying the convergence of data and voice.

| Alternative | How it compares |
|---|---|
| Nitel | Nitel is smaller but differentiates with managed SD-WAN services and NOC-as-a-service. Granite wins on scale (300+ carriers vs. 200+), volume pricing, and dedicated account management. |
| Comcast Business | Comcast delivers its own network directly and may offer better pricing in dense Comcast markets. Granite wins when the location estate spans multiple carriers or requires a single-vendor relationship. |
Granite's bulk purchasing power typically delivers 10–25% lower rates than what an individual business can negotiate directly — particularly for high-volume estates (100+ locations). For small estates (5–20 locations), direct carrier pricing may be comparable. Compare Select models both scenarios with real quotes before recommending.
Both. Granite operates Granite Dedicated Access (GDA), its own fiber network for enterprise locations requiring dedicated circuits. For other locations, Granite aggregates 300+ underlying carriers. The mix depends on what's available and most cost-effective at each site.
Most large estate migrations are phased over 90–180 days — locations are moved in batches as existing carrier contracts expire or with scheduled porting. Granite assigns a dedicated project team and Compare Select manages the overall migration timeline on your behalf.
