Biggest Calling Card Companies

Here is a list of the largest online calling card companies. These calling card rankings are based on data from Alexa.com, a web information company owned by Amazon.com.

The Alexa ranking are a measure of the amount of visitor traffic a site gets. The Alexa rank indicates the rank of each website as compared to all websites worldwide. An Alexa score of, say, 50,000 indicates that a website is the 50,000th most visited website in the world.

Alexa continuously tracks at least 20 Million websites worldwide. It is considered one of the most comprehensive and reputable sources of website traffic volumes. That said, compiling accurate traffic data for websites is very difficult, so their data should be viewed as rough and approximate, not exact.

Please also note that Alexa rankings are very fluid. Sites move up and down constantly - sometimes by a significant amount.

For details on how Alexa compiles their data and calculates website rankings, please visit the Alexa.com website.

The tables below list the top 25+ calling card companies for recent years. The first table shows top calling card rankings for 2009 and the second shows data for 2008.

Both tables show company name along with their Alexa ranking, whether we have reviewed them, and whether we recommended them. These ratings are primarily for online calling card companies (as opposed to companies that sell calling cards in retail stores) -- and it does not include the calling card operations of major telephone companies like AT&T or Verizon.
