If you’ve ever tried acquiring a virtual phone number in the U.S., you already know it’s more complicated than it sounds. What begins as a simple desire of “I just need a number for SMS or support” often leads into carrier forms, 10DLC approvals, compliance checks, and delayed activations.

And if your main goal is verification or global outreach, things get even more challenging. The truth is: having a virtual number doesn’t guarantee fast, reliable messaging or compliance.

But here’s the deal: when done right, virtual numbers offer tremendous flexibility for customer support, inbound messaging, global reach, and even security workflows. According to Grand View Research, the global virtual number market size was valued at USD 59.96 billion in 2022 growing at 27.5% CAGR to 2030. That growth alone shows how important this category is for modern businesses.

So whether you’re a startup, an app builder, or scaling globally, this guide will walk you through everything you need to know about Virtual Numbers in the USA.

A virtual phone number is a telephone number not tied to a specific physical line or SIM card. It lives in the cloud and can be used for:

• SMS
• Voice calls
• Two-way messaging
• WhatsApp or chat routing
• Call forwarding and IVR flows

Over 85% of consumers say good customer service makes them more likely to buy from a company again, according to a 2024 HubSpot survey used in Newsweek’s America's Best Customer Service 2025 report.

Virtual Number or Short Code or 10DLC? Choosing What Fits Your Use Case

One of the first stumbling blocks is selecting the right number type. Each option serves different purposes:

• Virtual Phone Number – best for customer support, low-volume SMS, inbound two-way messaging.
• 10DLC (10-Digit Long Code) – in the U.S., approved for application-to-person (A2P) SMS including alerts and verification; requires carrier registration.
• Short Codes – designed for high-volume marketing or alerts; fast throughput but expensive and slow to deploy.

How Much Do Virtual Phone Numbers Cost in the U.S.?

Pricing depends on several factors:

• Type of number (local vs toll-free vs mobile)
• Whether SMS is enabled
• Inbound vs outbound usage
• Volume of messages or calls

Typical pricing: local numbers may cost $1–10/month, while SMS-enabled mobile or toll-free can range $10–20+. But always check reliability – cheaper numbers often lack full carrier reach. According to TeleSign, low-quality numbers can lead to 20–30% higher message filtering rates.

Can You Buy a Virtual Number in the USA Without U.S. Business Registration?

Yes, in some cases. But expect stricter verification if the number supports SMS. Some providers require:

• Business registration
• U.S. address
• EIN

If you’re outside the U.S., you may find global-friendly providers. Still, compli­ance rules tighten when the number is used for A2P SMS.

Virtual vs VoIP vs Cloud Numbers – What’s the Real Difference?

Let’s clear the confusion:

• Virtual Number: cloud‐hosted, supports SMS / voice, flexible.
• VoIP Number: primarily for voice over IP, less reliable for SMS.
• Cloud Number: generic term for any number hosted in the cloud.

A recent report found that the cloud-based contact center market is growing rapidly with solutions expected to reach $82.43 billion by 2030, powered by the need for scalable and easy-to-manage customer experiences.

Can I Use a Virtual Number to Send SMS OTPs or 2FA Codes?

While technically possible, doing so reliably in the U.S. is tough. The industry has found that A2P OTPs sent over unfriendly routes face 30-40% failure rates, especially on networks like Verizon or T-Mobile. The risk: verification codes that don’t arrive = frustrated users.

Do Virtual Numbers Require 10DLC Registration in the U.S.?

If you use a number for A2P SMS (alerts, verification), yes, U.S. carriers require 10DLC registration: brand, campaign, and message templates. Without it, messages risk filtering, blocking, or delays. According to CTIA, over 90% of A2P SMS traffic must now pass 10DLC workflows to ensure compliance and deliverability.

How Fast Can I Activate a Virtual Number for My Business?

Activation times vary:

• Voice-only numbers: minutes to hours
• SMS Virtual numbers: hours to days
• Numbers requiring 10DLC or special approval: weeks

If you need instant onboarding, look for providers offering minutes-to-activate numbers.

Can One Virtual Number Reach Customers in Multiple Countries?

Sometimes yes, but with limitations. A U.S. virtual number can often send international SMS, but many local carriers filter or block A2P traffic. If you target multiple countries, a global messaging platform or local numbers may work better. According to Juniper Research, global A2P SMS traffic will reach 4.5 trillion messages by 2027, so global reach matters more than ever.

Can I Port My Existing Number to a Virtual Number Provider?

Yes — number porting is common. Expect documented proof of ownership and business identity. Porting can take 2–14 business days, depending on your carrier and region. Gartner notes that organizations planning to move numbers should budget 4–6 weeks for full transition and systems alignment.

Can a Virtual Number Integrate With WhatsApp, SMS APIs, or CRM Tools?

Yes, and it’s key for modern businesses. Your virtual number should plug into:

• WhatsApp Business (Read: Virtual Phone Numbers for WhatsApp Business)
• SMS APIs (send/receive)
• CRM and support platforms
• Two-way communication flows

Studies show that companies combining voice, SMS and messaging apps achieve a 33% higher customer satisfaction rate.

What to Look For When Choosing a Virtual Phone Number Provider

Here’s a quick checklist:

• Global coverage and carrier reach
• SMS & voice support across major networks
• Transparent pricing (monthly + per message)
• Quick activation times
• Strong deliverability logs & analytics
• Integration with APIs, SDKs, CRM tools
• Compliance support (10DLC, data-privacy)
• Reliable support and documentation

Final Thoughts

Virtual phone numbers open great possibilities: scalable support lines, SMS-capable numbers, global communication. But they’re not always plug-and-play — especially when used for OTPs or high-reliability SMS. Before you buy, weigh cost, carrier support, registration burden, and integration.

When done right, the investment can pay off big: better user experience, global reach, stronger support, and simplified infrastructure. With the right provider and strategy, you’re set to communicate confidently across the U.S. and beyond.

FAQs

Q) What documents do I need to buy or activate a virtual phone number in the U.S.?

A) For most virtual U.S. numbers, you’ll typically need basic business verification such as your business name, website, and a valid ID. If the number supports SMS (especially A2P traffic), carriers may also require proof of business registration, a U.S. address, or EIN. Requirements vary by provider, but the more capabilities the number has, the stricter the documentation tends to be.

Q) Should I get multiple virtual numbers for different regions or just one number for everything?

A) It depends on your use case. One number works fine for general customer communication, but multiple numbers help if you serve different states, want region-specific presence, or expect high inbound volume. Some businesses also use separate numbers for support, marketing, and operations to keep workflows clean and track performance more easily.

Q) What messaging volume is “too high” for a virtual number, and when should I switch to short codes or 10DLC?

A) Virtual numbers are best for low to moderate SMS volumes, usually under a few thousand messages per day. If you plan to send large bursts, time-sensitive alerts, or campaigns, a 10DLC (for A2P traffic) or a dedicated short code offers far higher throughput and better deliverability. As soon as you see slow delivery, queueing, or carrier filtering, it’s a sign you’ve outgrown a virtual number.
