What Real People Say About Us?

Experience why Voiply has become the top-rated home phone provider, trusted by over 50,000 satisfied customers.

We realized our house phone was not working and I e-mailed Voiply. They replied promptly, created a ticket # for us and began work on their end. Seems our adapter was off line so they gave me instructions on what to do. I followed their directions and we were back in service. Nice and easy--thank you.

We used Voiply service for many years with trouble free service. When it came time to cancel our service (just don’t use the land line anymore) they made this very simple to do. If we ever need a landline again we will definitely be back!

We recently switched our business landline to Voiply and had some issues after the porting process was complete. I contacted customer service, and they were able to resolve the issue quickly and get us up and running. The additional features provided by Voiply over a traditional landline phone are wonderful.

We have cut the cord with Xfinity’s ever raising prices for over 6 months now by using Voiply phone system. It was VERY easy to set up and works fine. We had an issue with not showing caller ID after 6 months and it was resolved within a day. I will definitely continue to extend our membership beyond the 1 year that we initially signed up.

I appreciate the time and attention that I received from the Voiply tech support agents when I was trying to resolve an issue with my adaptor. Mike walked me through a process to restore my service via the website chat and email. When neither of these methods was successful, Ana called me on my mobile phone and walked me through the process. Many thanks to their dedication in helping to resolve this issue.

Signup and porting my old number was simple and went flawlessly. Porting process also cancelled my old service so I didn't have to.

Frequently Asked Questions

Get answers to common questions about area codes.

What is an area code?

An area code is a three-digit number that identifies a specific geographic region in the telephone network where a call is either originated or destined.

Do different states have different numbers of area codes?

Yes, some states have multiple area codes, while others have only one. For instance, California has the most with 36 area codes, while several states like Alaska and Delaware have just one.

Why do we need area codes?

Area codes are necessary for routing calls within a country and ensuring that the call reaches the correct location.

Can an area code give an indication of a phone number's origin?

Yes, a phone number's area code can give a general idea of where a call originated from, or at least where the phone number was registered.

Can I keep my area code if I move to a different state?

Yes, with voiply you can keep your number when moving to a different state.

How many area codes are there in the United States?

As of the latest update in 2023, there are approximately 335 area codes in the United States.

What are non-geographic area codes?

Non-geographic area codes are not tied to a specific geographic area and are often used for specific services like toll-free numbers (800, 888, etc) or premium rate services (900).

Are area codes unique to each city?

Not necessarily. Some large cities may have their own area codes, but smaller cities and regions may share an area code.

What happens when an area runs out of phone numbers within its existing area code?

When an area exhausts its supply of phone numbers within an existing area code, a new area code is introduced in that geographic region. This process is known as an area code split or overlay.

How are new area codes created?

New area codes are created by the North American Numbering Plan Administration (NANPA) when the existing codes in a region are projected to exhaust. The decision to add a new area code is usually made several years in advance.
