Virtual US Phone Numbers Explained: Best Providers for Calls and SMS

Virtual US phone numbers have become a practical tool for entrepreneurs, remote teams, freelancers, international businesses, and anyone who wants a professional American phone presence without installing a landline. They work through the internet rather than a traditional phone cable, letting you make calls, receive texts, route conversations, and manage voicemail from apps, browsers, or business phone systems.

TLDR: A virtual US phone number lets you call and text using a US-based number from almost anywhere, usually through a mobile app or web dashboard. The best provider depends on whether you need simple personal calling, business features, team collaboration, or developer-friendly SMS APIs. For most small businesses, providers like OpenPhone, RingCentral, Dialpad, and Grasshopper are strong choices, while Twilio is best for custom SMS and call workflows.

What Is a Virtual US Phone Number?

A virtual US phone number is a telephone number with a US area code that is not tied to a specific physical phone line. Instead, it uses VoIP, or Voice over Internet Protocol, to send calls and messages over the internet. You can typically access it through a smartphone app, desktop app, browser, or call forwarding setup.

For example, a consultant in London can use a New York number, a startup in Singapore can offer a California support line, and a remote team spread across multiple states can all answer calls from one shared business number. To customers, it looks and feels like a normal US number.

Common Types of Virtual US Numbers

Not all virtual numbers are the same. The best option depends on your use case, budget, and whether you care more about calling, texting, branding, or automation.

  • Local numbers: These use familiar area codes such as 212, 310, 415, or 786. They are ideal for businesses that want a local presence in a specific city or state.
  • Toll-free numbers: Numbers starting with 800, 888, 877, 866, 855, 844, or 833 are often used for support, sales, and national brands.
  • Vanity numbers: These spell out memorable words, such as 1-800-FLOWERS. They are useful for marketing but may cost more.
  • SMS-enabled numbers: These can send and receive text messages, though rules vary depending on provider, number type, and registration requirements.
  • API-based numbers: These are used by developers to build automated call flows, verification texts, reminders, and customer messaging systems.

Why Use a Virtual US Number?

The biggest advantage is flexibility. You do not need to be in the United States, maintain a second phone, or expose your personal number. A virtual number can ring multiple devices, forward calls to a team, collect voicemail, send auto-replies, and keep business conversations organized.

Businesses also use virtual numbers to appear more trustworthy. A US number can reduce friction for American customers who may hesitate to call an international line. For solo professionals, it creates a clean separation between personal and business communication.

Another benefit is scalability. If your company grows from one person to twenty, many providers allow you to add users, departments, call menus, shared inboxes, analytics, and integrations with CRMs or helpdesk software.

Important SMS Rules to Know

Text messaging from virtual numbers is not as simple as it used to be. In the US, business texting often falls under A2P 10DLC rules, which means application-to-person messaging over standard 10-digit numbers may require brand and campaign registration. This is especially important if you plan to send marketing texts, appointment reminders, verification codes, or bulk messages.

Some services support SMS only for casual one-to-one conversations, while others support compliant business messaging at scale. Before choosing a provider, check whether it supports SMS, MMS, toll-free verification, A2P registration, opt-out handling, and message delivery reporting.

Best Providers for Calls and SMS

1. OpenPhone

OpenPhone is one of the most popular choices for startups, small businesses, and remote teams. It combines calling, texting, voicemail, shared numbers, internal comments, and team collaboration in a clean interface. It is especially good if your team wants a modern business phone system without the complexity of an enterprise platform.

Best for: small teams, startups, shared inboxes, business texting, and simple CRM-style communication history.

2. RingCentral

RingCentral is a full-featured business communications platform. It offers virtual phone numbers, voice calls, SMS, video meetings, call routing, auto attendants, analytics, and integrations with many business tools. It may be more than a solo freelancer needs, but it is powerful for established teams.

Best for: growing companies, call centers, sales teams, and organizations that need advanced routing and administration.

3. Dialpad

Dialpad focuses on cloud calling with AI-powered features such as call summaries, transcription, and coaching tools. It is a strong option for teams that spend a lot of time on calls and want insights from conversations. SMS support is available, though exact features may depend on the plan and region.

Best for: sales and support teams that want call intelligence, transcripts, and productivity tools.

4. Grasshopper

Grasshopper is a straightforward virtual phone system designed for small businesses. It offers business numbers, extensions, call forwarding, voicemail, and texting. It is less collaboration-heavy than OpenPhone and less enterprise-focused than RingCentral, but it is easy to understand and quick to set up.

Best for: solo business owners, local service providers, and small teams that mainly need a professional calling setup.

5. Google Voice

Google Voice is appealing because it is simple and affordable. For personal use, it can be a convenient way to get a US number for calls and texts. Google Voice for business is available through Google Workspace in supported regions, but it may not offer the same level of customer support, compliance tooling, or advanced SMS features as dedicated business phone providers.

Best for: personal use, light calling, freelancers, and Google Workspace users with basic needs.

6. Twilio

Twilio is not a typical phone app; it is a communications API platform. Developers use it to build custom calling and SMS systems, verification flows, appointment reminders, chatbots, and automated notifications. It is extremely flexible, but non-technical users may find it too complex without developer help.

Best for: developers, SaaS companies, automated SMS workflows, verification codes, and custom integrations.

7. VoIP.ms

VoIP.ms is a flexible, cost-conscious VoIP provider with US numbers, call routing, SMS on supported numbers, voicemail, and configuration options. It is popular with technically comfortable users who want control over pricing and setup.

Best for: budget-conscious users, technical users, and custom VoIP setups.

How to Choose the Right Provider

Before signing up, decide what you actually need. A provider that is excellent for voice calls may not be ideal for high-volume texting. A platform built for developers may be frustrating if you simply want a business number on your phone.

  • For simple business calls and texts: OpenPhone or Grasshopper are easy starting points.
  • For larger teams: RingCentral and Dialpad offer stronger administration, analytics, and routing.
  • For personal or lightweight use: Google Voice may be enough.
  • For automation and APIs: Twilio is the strongest option.
  • For low-cost technical setups: VoIP.ms is worth considering.

Also check practical details such as number availability, international access, SMS registration requirements, voicemail transcription, mobile app quality, call recording, customer support, and cancellation policies.

Final Thoughts

A virtual US phone number is more than a convenient second line. Used well, it becomes a professional communication hub for calls, SMS, voicemail, support, sales, and customer relationships. The best provider depends on your goals: OpenPhone for modern small-team communication, RingCentral or Dialpad for advanced business calling, Grasshopper for simplicity, Google Voice for light use, Twilio for programmable messaging, and VoIP.ms for flexible low-cost VoIP.

Before choosing, think beyond the number itself. Consider how your customers will contact you, how your team will respond, and whether SMS compliance matters for your use case. A good virtual number should make communication easier, more professional, and more scalable from day one.
