AVOXI provides US virtual phone number types, each fully configurable online with instant activation and integration-ready setup for call forwarding, IVR, and inbound call handling.
Toll-Free
Professional numbers that are free for callers to dial. US toll-free numbers are available across seven active dial-code prefixes — 800, 888, 877, 866, 855, 844, and 833 — and are ideal for customer service and support functions where accessibility and national reach matter.
TrueLocal Caller ID
Two-way inbound and outbound phone numbers with a verified local caller ID to drive higher answer rates — an increasingly important differentiator as US carriers apply “Spam Likely” and similar labels to unfamiliar or unauthenticated numbers.
Local DID
(Direct Inward Dialing)
Inbound numbers with city- and region-specific three-digit area codes across all 50 states. Local presence builds trust with US customers and can support local search visibility for multi-location businesses.
US Local DID Numbers
US local numbers give your business a direct, city-specific point of contact that customers recognize and trust. For multi-location businesses and national brands, local numbers are one of the most effective ways to build a neighborhood presence at scale — without opening a physical office in every market.
The US numbering plan (the North American Numbering Plan, or NANP, shared with Canada and several Caribbean nations) uses a three-digit area code followed by a seven-digit local number, for ten digits in national format. Ten-digit dialing is standard practice today, and mandatory in numbering plan areas with overlay codes or that share a region with the 988 Suicide & Crisis Lifeline. A full US number in international format looks like +1 XXX XXX XXXX.
AVOXI's US local numbers can be forwarded to any contact center or communications application, device, or team, anywhere in the world. Whether your team is based in the same city as the area code or operating from a global headquarters, your customers always reach a familiar, local-feeling number. For businesses building a presence in a specific US market — or consolidating numbers across many US markets onto one platform — local DID service is often the most direct option.
US Toll-Free Numbers
Toll-free numbers put no cost burden on your callers, making it easier for customers to reach your business without hesitation, regardless of which US region they're calling from. For national brands, professional services, and contact centers, a toll-free number signals scale and accessibility.
AVOXI's US toll-free numbers are available across the seven prefixes currently released under the North American Numbering Plan: 800, 888, 877, 866, 855, 844, and 833. All are functionally identical from the caller's perspective — none carries an inherent quality or reliability advantage, only differences in availability and brand recognition, with 800 being the oldest and most recognized. The next prefix, 822, is reserved by the FCC for future release but has no announced date and isn't yet available for provisioning. Toll-free numbers are portable between providers through the industry's RespOrg system, and every AVOXI toll-free number is provisioned to handle high call volumes reliably across the US telecommunications infrastructure.
Two-Way Local Caller ID & Outbound Trust in the US
Nowhere is verified caller ID more commercially important than in the US. Since June 30, 2021, the FCC has required voice service providers to implement STIR/SHAKEN caller ID authentication — a framework that lets carriers cryptographically verify that a call's displayed number is legitimate — and has continued closing gaps in that framework on a rolling basis, including a 2025 rulemaking addressing non-IP portions of the call path. Calls that can't be authenticated, or that come from numbers with a poor reputation, are increasingly likely to be flagged “Spam Likely” or blocked outright by carrier analytics, regardless of whether the call is legitimate.
This is exactly the problem AVOXI TrueLocal is built to solve: a consistent, verified local or national caller ID for outbound calling, so customers see a recognizable number rather than a flagged or unfamiliar one. That same number can receive inbound callbacks, creating a more natural, trustworthy customer experience. For sales teams, collections, appointment reminders, and any outbound-heavy US operation, protecting caller ID reputation directly protects answer rates.
Replacing legacy PSTN lines or a patchwork of regional carriers with AVOXI's SIP-based infrastructure gives enterprise teams centralized control over call routing, number management, caller ID reputation, and voice quality through a single online platform. All traffic runs over Tier 1 networks, with real-time monitoring across latency, jitter, and packet loss.

Key Regulations for Voice Services in United States
Voice and telecommunications services in the US are regulated primarily at the federal level by the Federal Communications Commission (FCC), under the Communications Act of 1934 as amended by the Telecommunications Act of 1996. Interconnected VoIP providers — including AVOXI — are subject to a specific set of FCC obligations that traditional carriers have followed for decades, covering caller ID authentication, emergency calling, number portability, and consumer privacy. Several of these obligations, like Kari's Law, apply directly to businesses operating multi-line telephone systems (MLTS) — not just to the voice provider.
Regulatory Overview
The FCC classifies AVOXI and similar cloud voice providers as interconnected VoIP providers, subject to obligations that include caller ID authentication (STIR/SHAKEN), emergency calling (E911, Kari's Law, RAY BAUM'S Act), number portability, Customer Proprietary Network Information (CPNI) protection, and Universal Service Fund (USF) contribution requirements. AVOXI maintains compliance with applicable FCC rules across its US voice infrastructure.
Key Compliance Requirements
Caller ID Authentication (STIR/SHAKEN):
Since June 30, 2021, the FCC has required voice service providers to implement STIR/SHAKEN caller ID authentication on the IP portions of their networks, under authority granted by the TRACED Act. The FCC has continued closing gaps in the framework on a rolling basis — most recently addressing non-IP portions of the call path and third-party call-signing arrangements in 2025. For enterprises, this framework underpins caller ID trust: calls that can't be authenticated are more likely to be flagged or blocked by carrier analytics.
Emergency Calling — Kari's Law & RAY BAUM'S Act:
Since February 16, 2020, Kari's Law has required multi-line telephone systems (MLTS) — the kind used by most contact centers and multi-line offices — to support direct 911 dialing with no prefix digit, and to send a notification to a front desk, security office, or other on-site or off-site location when a 911 call is placed. Section 506 of the RAY BAUM'S Act separately requires that 911 calls convey a “dispatchable location” (validated street address plus suite, floor, or room information) to the local public safety answering point, with compliance deadlines of January 6, 2021 and January 6, 2022 depending on the type of device. These obligations apply to the businesses operating an MLTS as well as to the service providers behind it.
Number Portability (LNP):
Under FCC local number portability rules, subscribers can keep their number when switching providers, including switching to or from an interconnected VoIP provider, as long as they stay in the same geographic area. “Simple” ports — the kind most business number transfers fall under — must be completed within one business day. AVOXI supports free number porting for numbers customers want to keep.
Telemarketing & Robocall Rules (TCPA):
The Telephone Consumer Protection Act (TCPA) and FCC rules place strict consent requirements on autodialed, prerecorded, or artificial-voice calls and texts — particularly for telemarketing purposes — and require an easy opt-out mechanism. These rules apply to businesses making outbound calls through AVOXI's platform; enterprises running outbound campaigns should route consent and compliance questions to their own legal counsel.
Consumer Privacy (CPNI):
The FCC's Customer Proprietary Network Information (CPNI) rules protect call detail and account information collected by voice providers, including authentication requirements the FCC strengthened in 2023 in response to SIM-swapping and port-out fraud. AVOXI maintains CPNI safeguards across its US voice services.
Universal Service Fund (USF) Contribution:
Interconnected VoIP providers, including AVOXI, are required to register with the FCC (via FCC Form 499-A) and contribute to the Universal Service Fund based on reported revenues. This is a standard obligation across the US voice industry and does not typically affect customer pricing or setup.
AVOXI & US Regulatory Compliance
AVOXI's US voice infrastructure is built to support these obligations — from caller ID authentication to emergency calling to number portability — so enterprise customers can focus on their business rather than telecom compliance mechanics. Our team can help guide you through the specific requirements for your use case.
