Toll free numbers are also referred as 800 Numbers in North America because of their numbering system. One had to dial these numbers after the original area code. Some of the area codes that had to be dialed were code numbers were 800, 888 (since 1995). Code number 877 (since 1997), code number 866 was included in the year 2000. Also, there were other numbers like 855, 844, 833 and 822 which are not yet active but are reserved.

There is a difference in the way we use a normal telephone number and the way we use a toll free number. The general way of writing a telephone number is “+” sign attached with the country code, followed by area code and then the local number, for example: +1 (666) 123-1234. But, when we use a toll free number which are not accessible from other countries, we should eliminate the “+” sign and the round brackets, for example: 1-800-123-1234.
