Buy a US Virtual Phone Number

You are a business owner or manager looking for an American phone number.

Whether you are entering the US market for the first time or need a local support line for existing American customers, you are in the right place. Below we explain which number types are available, and how we set everything up for you — typically within one business day.

A foreign number on your website signals “overseas company” and often triggers hesitation. Many Americans are unfamiliar with international dialling and some will simply not call. A US toll-free number or a local area code is something they understand instantly.

It sits naturally on your website, invoices, Google Business listing, and advertising. For B2B, a US number is practically a requirement if you want procurement teams to take your enquiry line seriously.

A toll-free or local American number tells your US audience that you are serious about doing business with them.

The United States is the single biggest commercial market globally, with vast international bilateral trade.

Whether you sell products, deliver services, or run campaigns targeting American consumers, a US phone number removes one of the most basic barriers: the ability for your customers to call you on a number they recognise and trust. American consumers and business buyers expect to see a domestic phone number.

The United States covers multiple time zones, from Eastern (UTC−5) to Pacific (UTC−8) and beyond. CallFactory lets you configure time-based routing rules so that calls are handled differently depending on when they come in.

During business hours, calls can ring straight through to your team.

During off-hours, they can go to voicemail with a professional message, forward to a colleague in a different time zone, or route to a mobile. This means you can offer genuine US business-hours availability from abroad, even with a five-to-eight hour time difference.

Both toll-free and local numbers are available to businesses with a worldwide address.

Toll-free numbers (800, 888, 877, 866, 855, 844, 833) are free for the caller and work nationwide. They are the standard choice for customer support lines, sales hotlines, and any situation where you want to remove all cost barriers for the caller. American consumers associate toll-free numbers with established, trustworthy companies. If you serve customers across multiple states, toll-free is usually the best starting point.

Local area code numbers give you a presence in a specific city or region. A 212 number says “New York”, a 310 says “Los Angeles”, a 312 says “Chicago”. These are ideal if you are targeting a particular metro area, running location-specific campaigns, or want to appear as a local business in a specific market. You can hold multiple local numbers across different cities under the same CallFactory account.

US numbers follow the North American Numbering Plan: a 3-digit area code plus a 7-digit number. The country code is +1.

Format as +1 212 555 1234 for international use, or (212) 555-1234 for a US domestic audience. A 212 number signals New York, a 310 signals Los Angeles, a 312 signals Chicago.

When advertising your US number on your website or marketing materials, use the format your audience expects — the domestic format for US-facing pages, the international format for global pages.

When a customer in the US dials your American number, the call is routed through our network and forwarded to wherever you choose: your landline, a mobile, a VoIP system, or a team of agents through a phone menu.

The caller hears a standard US ringtone and, if you like, a professional welcome message generated by our text-to-speech engine. There is no noticeable delay or quality loss — the call sounds like any other domestic American call.

On your end, you answer the call as normal, with a short beep or announcement letting you know it came in on your US line so you can greet the caller appropriately.

We have been a specialist virtual number provider established in the Netherlands in 2000 with Dutch management.

We are not a reseller — we run our own IVR platform and phone network, which means superior audio quality, full control over features, and no middlemen. Start simple with basic call forwarding, and scale up when you are ready. Need a fully custom-built IVR flow, dedicated servers, or private API access? We can build that too.

We are registered as a telecom provider in 14 EU countries, so as your business grows across Europe you stay with one provider instead of juggling multiple vendors.

A US phone number from CallFactory fits naturally into several common scenarios.

E-commerce brands selling to American customers can display a US number on their storefront, building trust and making returns and support feel effortless — especially important in a market where consumers expect to be able to call.

SaaS and technology companies can offer US-based support and sales lines, routing calls by time zone so East Coast and West Coast customers are always covered.

Recruitment agencies placing candidates in the US or hiring American talent can provide a local or toll-free callback number, improving response rates.

Professional services firms such as consultants, accountants, or legal advisors working with US clients project a permanent American presence without maintaining a physical office.

Importers and exporters can give US suppliers and logistics partners a domestic contact number, simplifying communication across the Atlantic.

Unlike most European countries, the US does not require a local address for any number type. Both toll-free and local area code numbers are available with a worldwide address.

You do not need a US subsidiary, registered agent, or physical office.
