“Call toll-free 1-8XX-XXXX!”

800, 833, 844, 855, 866, 877 and 888 numbers are EVERYWHERE. Of course you find them on television, but you also see them in advertisements on the internet and in your newspapers.
But what are they? Can one of these numbers help you? Your business? Why are they so widespread?
Basically, what’s the value of a number starting in 800, 833, 844, 855, 866, 877 or 888?

For one, all of these numbers:
a) have a national presence, and
b) are toll free.

At no cost to the caller whatsoever, your clients can place a call (or even text!) any of these numbers.

Let’s talk more about how useful these numbers are!

What is a toll-free number?

Toll free numbers are numbers that can be called at no cost to the caller (in effect, they are “free” of “tolls”). Instead, the receiver of the call takes on any costs associated with the call. While this would seem to not make a ton of sense for the average homeowner, it’s great for businesses. Why?

Well, for one, a customer is way more likely to call a business if they don’t have to pay for it (especially when that call may involve waiting on hold). Plus, having a toll number just gives your business that extra oomph of professionality.

Can I send text messages with one of these numbers?

Yes you can! As long as your number is text enabled customers can text your toll-free numbers and you can text back.

Do these work nationwide?

Not only do they work nationwide, but these numbers work in Canada too! In fact, the national recognition is a key positive of toll free numbers. They allow callers from around the country to call you for free.

Is there a difference between all of the different numbers, like 800 or 855?

Nope! The reason why there’s different numbers is because the government needed to make new ones- they’re so popular they were running out!

How can I use a 800, 833, 844, 855, 866, 877 or 888 number for marketing?

A great way is what’s called “call-tracking”. When using offline campaigns (like ads in magazines, on billboards, television, radio, etc.), get a separate toll free number for each, then track who is calling what number. That way you can see which campaigns are successful and which can be improved.

What’s a vanity toll-free number?

Vanity numbers are the numbers you see that are something  like “1-855-555-DOGS”. They’re easily memorizable and stick in your head. Vanity toll-free numbers simply combine the two concepts, so that you’d get something like “1-855-555-DOGS”, giving you the best of both worlds.
