Automated Phone number verification

Clean up your phonebook by verifying if the contact’s landline or mobile number is valid.

Analyse your phonebook before you start your campaign

Keeping data clean and accurate is hard. Our phonebook analysis service lets you analyse entire phonebooks and weed out the bad numbers. You can then decide to either correct the phone number or remove it from your phonebook. This gives you a lot of flexibility.

We recommend that you verify the contacts in your phonebook early so that you have time to correct any numbers that are invalid. Your voice or SMS campaign will then have a higher success rate.

What I really enjoyed was the relation we had. Every time anything had to be improved, we had a great correspondence with the CallHub team and they were very reactive; so every time we felt there was need to improve the tool to change something, they developed it quite quickly. It was very interesting, very stimulating, because we could go further every time we had what appeared to be an issue about CallHub.

CallHub has become my go-to platform for affordable phone canvassing campaigns, voice broadcasts and text message blasts. In particular, text message blasts are the single most useful tool for volunteer mobilization that I have used in recent years.

Very easy to use. I compared it to several other services and am very happy that we have chosen to do business with them. The team is so friendly, easy to work with and assists wherever they can. It is a joy to work with them!

A lot of our folks are volunteers, a lot of them are retired, they are often anxious with technology and they were able to use CallHub easily. It’s empowering for volunteers who don’t see themselves as very tech-savvy to be able to pick up a new piece of software and a new program and just use it, so that was great.

I love this product. It's so easy to use with a very clean user interface. The price is the most economical I've seen in the industry and last but not least is the wonderful customer support. They answer all questions very quick.
