Testimonials mentioning this resporg (8)
This is the fourth Toll Free number I have purchased from you. I did some research and I have to say that you guys at TollFreeNumbers are way ahead of your competition. Your website is one of the most user friendly websites I have came across with, loaded with tons of hard to find and honest information about your industry. But what I like most is your outstanding customer service which leaves me with absolutely no doubt to be a returning customer of yours. The most recent Toll Free number I have purchased from you (1-855-I-NEED-LIMO) for only $49 can not get any better. ONLY $49... are you kidding me? your competition was charging me arm and a leg for the same number, over 20 times more than you. I wish you only the best. I hope one day TollFreeNumbers.com will be bigger than AT&T and Verizon, because your customer service is much better.

After several unsatisfying encounters with Verizon to find an 800 #, I found your company on Google. Awesome! Couldn't be any better. Thanks for an ENJOYABLE experience.
— SAMUEL HAMMAKER, 2/25/12
Rita, Bill and Gloria; WOW!! Your services are amazing! I used your services for a toll free number that I could not obtain from any other company including Verizon. I expect to be kept up to date with important information and timely service with my order. Your company did both! That is CUSTOMER SERVICE. I will recommend tollfreenumbers.com to everyone and I too will include you on my website. You will appear on my sponsors" page."
— Mark German, 5/10/10
. Honestly, I was a little skeptical to get my toll free number from your small company. I called many of the big phone companies, like AT&T, Verizon, etc and found myself spinning in circles trying to get a number without being locked into a costly contract. Your service was smooth, easy, and very quick from purchase to transfer. Thanks again to your team. My business has a great vanity number because of you!
