866 area code: What it is and how to get a toll-free number

866 area code numbers

800, 888, 877, 866 area code — the list seems endless! You may have heard of some or all of these prefixes before — that’s because they’re all toll-free area codes.

While many small businesses opt for local numbers that give clients some idea as to their geographic location, that’s not always the best business move. 

Local numbers can come off as less polished and can also pose logistical challenges for international business communications.

Sometimes, clients may even assume you’re a scammer if they receive a call from an out-of-area number. Instead, you may want a toll-free business number with an 866 area code. 

We’ll explain what an 866 toll-free number is, the benefits of having one, how it functions in the US and Canada, and how to get one for your business.

What is an 866 area code number?

Simply put, the 866 area code is reserved for toll-free calls and assigned by the Federal Communications Commission (FCC). Toll-free calls charge the party being called rather than the person placing the call. 

What is the location of the 866 area code?

Toll-free numbers like the 866 area code aren’t located and tied to a particular geographic area or time zone. This makes it easier to perform business overseas and for customers to dial toll-free within the US, Canada, and other countries and regions included in the North American Numbering Plan (NANP). From a business perspective, that means 866 area codes appeal to a broader audience, as callers can reach an 866 number without paying long-distance fees. This is especially useful for customer service, sales, and technical support teams.

Benefits of having an 866 toll-free phone number

What can your business stand to gain from using a toll-free phone number like the 866 area code? The number of benefits may surprise you:

1. Look more professional

Businesses with an 866 toll-free number tend to make an excellent impression on clients looking to avoid scams. Businesses with toll-free numbers appear larger and more established to customers, which can help your company land more clients or simply boost your brand credibility. 

2. Appeal to customers worldwide

Toll-free numbers aren’t tied to a specific geographic area, meaning your business isn’t anchored in one place either. An 866 area code demonstrates your company’s desire and ability to serve North America and beyond, expanding your potential customer base.

The credibility of an 866 number also means you’re likely to receive calls from much farther away than you might otherwise.

What’s more, your calls won’t be mistaken for spam by customers living halfway across the country. 

3. It’s easy to use

A toll-free telephone number works just like a local number, making it intuitive and easy to use. Plus, with a service like OpenPhone, you can send and receive calls, text messages, images, videos, GIFs, and more. Once you have an active paid account (no longer on a free seven-day trial), you can complete toll-free number registration to text.

4. Customers won’t be charged

Are your customers sick of paying long-distance calling fees? With a toll-free number, anyone located within the 20 countries and territories on the North American Numbering Plan (NANP) can call you for free, even if they’re placing an international call. That includes the Caribbean, Jamaica, and more!

With OpenPhone as your VoIP business phone provider, you’ll get unlimited outbound free calling to anyone in the US and Canada.

5. Personalize your number

If you’re not already sold on the above features, consider using your new toll-free business phone number as a marketing tool.

Vanity numbers allow you to customize your phone number so that it spells a word or acronym. Within the 866 area code, Zipcar fields customer calls at 1-866-4ZIPCAR, while SBC Communications does the same at 1-866-SBC-DIAL. Vanity numbers have shown themselves time and time again to be more memorable for customers than randomly generated phone numbers.

How 866 toll-free numbers work in the US and Canada

Because the US and Canada are members of the North American Numbering Plan, customers in these areas can place toll-free calls to an 866 phone number. This gives your customers (and potential customers) both convenience and affordability. 

But your customers aren’t the only ones who benefit from your 866 toll-free number. With OpenPhone, you can make unlimited outbound calls to anyone in the US and Canada, saving you money.

How are 866 area code numbers different from other toll-free numbers?

The short answer here is simple: There is no functional difference between 866 area code numbers and other toll-free area codes, like the 800 area code or the 855 area code (except your customers will need to call the right area code for your toll-free number). 

In fact, the reason for so many different toll-free area codes may surprise you. Up until 1996, there was only one toll-free area code: 800.

That all changed when the FCC, the governing body in charge of assigning toll-free numbers, ran out of 800 numbers. They created an 888 area code to handle overflow requests and kept adding new area codes as demand for toll-free numbers increased. By doing so, the FCC ensured its ability to provide unique numbers to all businesses that request them. Your business could be next!
