A Freephone telephone number used in most of the world (or toll-free number in North America, and Freecall number in Australia) is a special telephone number, in which the calling party is not charged for the call by the telephone carrier. Instead the called party pays all of the charges for the call to the telephone operator, usually based on factors such as the amount of usage the number experiences, the cost of the trunk lines to the facility, and possibly a monthly flat rate service charge.
they charge the calling party in another way, such as for technical support calls.
they make a sale following the call to the toll-free number.
previous sales were enhanced with the inclusion of toll-free support.

History
Toll Free numbers were introduced to the telecommunications industry by AT&T in the 1960s.
Toll-free fax telephone number
A toll-free number that is used for faxing purposes. It can be used with internet faxing as well as traditional fax machines.
International Universal Freephone numbers
A universal international freephone number (UIFN) is a worldwide toll-free "800 number" issued by the ITU. Like the 800 area code issued for the NANP in the U.S. and Canada, the call is free for the caller, and the receiver pays the charges. UIFN uses ITU country code 800, so that no matter where the caller is, only the international access code (IAC) and the 8-digit UIFN need to be dialed. Currently, about 30 countries participate in the UIFN program.
Freephone around the world
Countries around the world use different area codes to denote toll-free services in their own networks. Some examples are:
In Australia, the prefix is "180x" (where x is currently 0 but allows for future expansion), for Freephone (or free call) numbers and are often referred to as "1800 numbers". They used to be called "008 numbers". 1800 numbers in Australia are 10 digits long 1800 XXX XXX, and are routed through to normal land line numbers. This is all about to change again now with the introduction of PHONEWORDS which will include 13, 1300 and 1800 numbers that translates to words or more commonly known as phonewords .
In Argentina, the prefix for toll-free numbers is "0800", followed by seven digits. These numbers are called "0-800" (cero ochocientos) or "líneas gratuitas" (free lines).
In Brazil, the prefix is "0800" - although phone numbers are 7 or 8 digits - it is followed by 6 digits. Toll-free numbers in Brazil can be accessed from any telephone (by default) in Brazil, with many exceptions. They can be accessed from outside Brazil only with a calling service (such as Vonage internet phone or MCI Worldcom calling service) that access numbers from within the called country. Many toll-free numbers are not available from cell phones (usually blocked by the cell phone provider rather than the provider of the toll-free number in an effort to prevent low-price competition from calling card providers). Some toll-free numbers are not available from phones listed by the owner of the number, including many payphones. For example, the MCI Worldphone calling service blocks usage from the payphones in international airports (Rio and São Paulo) and many downtown pay phones due to "excessive fraud" from those phones (July 2003). In addition, Brazil has a system of regular and international pay phones (designated with the symbol "DDD"). Toll-free numbers to international calling plans can be reliably used from non-DDD payphones, as of 2005.
In Bulgaria, the toll-free prefix is "0800" followed by a five-digit number (up to now, only 1XXXX and 20ххх numbers have been allocated). These numbers are called "Зелен номер" (Green Number) by BTC and "Зелена линия" (Green Line) by M-tel.
In Chile, the toll-free prefix is "800" followed by a six-digit number. These numbers are called "número 800" (800 number). These numbers can not be accessed from abroad.
In China, the prefix is "800" for toll-free numbers and often referred to as "免付費电话".
In Denmark and Norway most telephone-numbers have eight digits (some exceptions). The toll-free numbers all begin with "80" followed by six further digits.
In Egypt, it starts with (800) followed by the number.
In Ecuador, it starts with 1800 followed by 6-digit numeber. Some numbers have either regional or nationwide access. Calls from cellphones are only allowed by the operator Alegro which charges a few cents for these calls. PORTA and movistar does not allow the service.
In the European Union, there is a freephone number, working only inside the Union, called "Europa Direct", that provides information about Europe. The number is "00 800 6 7 8 9 10 11" (+800 can be used from cellular phones). This is an ITU UIFN, i.e. +800 6789 1011.
In France, and also in Belgium, the "0800" prefix is used for toll-free numbers. They are also known as numéros verts (green numbers).
In Germany, the toll-free prefix is "0800" followed by a seven-digit number. The "0801" prefix is already reserved for future use. The prefix was formerly "0130". Deutsche Telekom calls these numbers "freecall 0800", most Germans refer to it simply as Servicerufnummer (service number).
In Greece, the toll-free prefix is "800" followed by a seven-digit number. The seven-digit number can be either "800" followed by a four-digit number, or "11" followed by a five-digit number.
In Hong Kong, toll-free numbers have "800" prefix.
In Iceland, the toll-free prefix is "800" followed by a four-digit number.
In India, toll-free numbers used to begin with "1600" now the same numbers should be called using "1800".
In Indonesia, the toll-free prefix is "0800" followed by a seven-digit number.
In Ireland, 1800-xxxxxx numbers are freephone, with some sub-sections reserved, such as 666xxx being reserved for police services, and 111xxx being reserved for so-called 'snitch' lines, including insurance fraud and breaching of the workplace smoking ban.
In Israel, the toll-free prefix is "1800" followed by 6 digits.
In Italy, toll-free numbers are dialed with the "800" or "803" prefix and are commonly referred to as "Numero Verde" (green number). Back in the days, the "Numeri Verdi" used to begin with "1678" and later with "167".
In Japan, the prefix "0120" is used for toll-free numbers and is often referred to as "free dial" (フリーダイヤル).
In New Zealand, both "0800" or "0508" prefixes are referred to variously and interchangeably as "free phone" or "toll-free". Originally these "Oh-eight-hundred" numbers were provided by Telecom NZ and "0508" by rival company Clear (now TelstraClear), although now both numbers can be provided by either company. Some older toll bar services designed to restrict toll calls (including long distance or calls to mobile phones) will also block calls to these free phone numbers, although this has become less common since the mid 1990s. A limited number of companies utilizing toll-free numbers will not accept calls from mobile phones. Some other free phone services exist, such as "*555" ("star five five five"), which can be dialled from cellular phones to report traffic conditions and incidents of dangerous driving.
In the Netherlands, the prefix "0800" is used for toll-free numbers.
In Pakistan,toll-free numbers have the following format "0800-xxxxx".
In the Philippines, the prefix for toll-free numbers is "1800" followed by either one, two, or four digits (examples include 8, 10, and 1888) followed by either a four- or seven-digit phone number.
In Poland, toll-free numbers have the following format "0800 xxx xxx".
In Portugal, the prefix is "800" so the 9-digit number is "800 xxx xxx". It is referred as "Chamada Gratuita" (Free Call) or as "Número Verde" (Green Number).
In Romania, the prefix is 08008 is used for toll-free numbers. The service is referred to as "Telverde".
In Russia, the prefix is "8""800", so call is 8-800-XXX-XXXX.
In Serbia, the prefix "800" followed by a 6 or 7 digit number is used
In Slovenia, the prefix "080" is used for toll-free numbers, followed by four more digits.
In South Africa, the prefix "0800", followed by 7 digits is used. It is referred to as a "toll-free" or "0800" number (Afrikaans: tol-vrye).
In Spain, the "900XXXXXX" or "800XXXXXX" numbers are always toll-free (800 numbers are not usually used), "909XXXXXX" is used for dial-up Internet service and toll-free dialup Internet service (under subscription). Also "1002", "1004", "14XX", "15XX" and "16XX" are free and are used for the telecommunication providers call centers. However, in Spain with most providers, the calls from landlines to landlines are free so you might call to "9XXXXXXXX" or "8XXXXXXXX" for free (except "90X" and "80X" when "X" is not 0)
In Sweden, the prefix is "020" for toll-free numbers. (Additionally, 0800 is reserved for future use.)
In Switzerland, the toll-free prefix is 0800; previously it was 155. These numbers are called « grüne Nummer / numéro vert / numero verde » (green number).
In the UK, numbers starting "0500", "0800" or "0808" are free. The range 0808 1570xxx is set aside for fictitious uses in TV and radio. Additionally, numbers in the range 0808 80xxxxx are reserved for not-for-profit helplines. Since Orange UK introduced charges for dialing freephone numbers in December 2005, all British mobile networks now charge for calls to freephone numbers, with certain limited exemptions (notably Childline).
Toll-free numbers in the North American Numbering Plan (NANP) are sometimes called "800 numbers" after the original area code which was used to dial them. They include the area codes 800, 888 (since 1996), 877 (since 1998), 866 (since 2000), 855 (since 2000 although not yet in use), 844, 833 and 822 (the last three are not yet active but reserved). When they first appeared toll-free numbers were often referred to as in-WATS numbers (see WATS lines). When a NANP telephone number is written or printed as an international number, the number should be prefixed by a "+1" and a space, e.g.: +1 555-555-5555. The groups of digits within the NANP number should be visually separated by dashes, spaces or periods per ITU-T Rec. E.123 to make them easier to recognize and remember. However when writing toll-free numbers that are not accessible from other countries, in order to make it clear that the initial 1 is not a country code, the plus-sign (+) and space should not be used, e.g. 1-800-555-5555. Restrictions (such as the number is not available from pay phones, cell phones, Canada, or other countries) should also be stated with any listing, but often are not. Some sources still say that the phone company can charge for some 8xx numbers. These sources recommend always checking with the telephone company before making any call. However, phone companies are generally not cooperative with this procedure, and it is cost-prohibitive anyway. Although phone companies do not charge the caller for any toll-free number, charges may be billed by the recipients of these calls by some other method.
Some regular area codes may be deceptively similar to toll-free prefixes, such as 801 (Central Utah), 860 (Eastern and Northwestern Connecticut), 814 (Western and Central Pennsylvania), and 818 (Los Angeles, California). This similarity has also been exploited by fraudsters in international locations that can be direct dialed with what appear at first glance to be domestic area codes such as 809 (Dominican Republic). Toll-free numbers are also sometimes confused with 900-numbers, for which the telephone company bills the callers at rates far in excess of long-distance service rates for services such as recorded information or live chat.
The toll-free numbers can only be called from certain phone numbers, depending upon the preferences of the customer (and sometimes the provider) who has the phone numbers. The default is that these numbers are available from any phone in Canada or the USA. However, many US toll-free numbers cannot be accessed from Canada, and many Canadian toll-free numbers cannot be accessed from the USA. Some are not accessible from pay phones (which the provider passes as an ANI code). Calls from payphones assess the toll free owner an additional fee in the USA as mandated by the FCC. Although toll-free numbers are not accessible internationally, many phone services actually call through the USA, and in this case the toll-free numbers become available. Examples of these services are the MCI Worldphone international calling card, and Vonage internet telephone. However, many calling card services charge their own fee when their toll-free numbers are used to make calls, or when their toll-free numbers are used from pay phones.
From many countries (e.g. the UK), US toll-free numbers can be dialed, but the caller first gets a recorded announcement that the call is not free, and perversely, on many carriers, the cost of calling a 'toll-free' number can be higher than to a normal number.
US toll-free numbers could at one time be accessed from certain other NANP countries on a paid basis by replacing the 800 by 880, 888 by 881, and 877 by 882. Thus, to reach 1-800-xxx-yyyy from a NANP country where it was blocked, 1-880-xxx-yyyy could be dialed. Areas codes 880, 881 and 882 have since been recovered.
A limited number of US toll-free numbers may be accessed internationally free of charge to the caller by dialing through the AT&TUSADirect service. This is one way in which US companies may provide toll-free customer service to their international clients.
In addition, US toll-free numbers may be accessed free of charge regardless of the caller's location by some IP telephone services.
The format of the toll-free number is called a non-geographic number, in contrast to telephone numbers associated with households which are geographic. (Since the advent of cell phones (1985) and internet phone services such as Vonage (2002) households can have any area code in the USA--it is still geographic in the sense that calls from that area code are considered local, but the recipient can be physically anywhere). In the latter case, it is possible to determine an approximate location of the caller from the dial code (e.g. New York or London). Toll-free numbers in contrast could be physically located anywhere in the world.
When a toll-free number is dialed, the first job of the telephone operator is to determine where the actual physical destination is. This is achieved using the intelligent network capabilities embedded into the network.
In the simplest case, the toll-free number is translated into a regular geographic number. This number is then routed by the telephone exchange in the normal way. More complicated cases may apply special routing rules in addition such as Time of Day routing.
Technical Description of toll-free number routing in the U.S.
The IXCs generally handle traffic crossing boundaries known as LATAs (Local Access and Transport Areas). A LATA is a geographical area within the U.S. that delineates boundaries of the LEC. LECs can provide local transport within LATAs. When a customer decides to use toll-free service, they assign a Responsible Organization (RESPORG) to own and maintain that number. Usually the RESPORG is the IXC that is going to deliver the majority of the toll-free services.
Taking a closer look, when a toll-free number is dialed, each digit is analyzed and processed
by the LEC. The toll-free call is identified as such by the service switching point (SSP). The
SSP is responsible for sending call information to the signal transfer point (STP). The STP asks the service control point (SCP) where to send the call.
The LEC will determine to which IXC that number is assigned, based on the customer's choice. Toll-free numbers can be shared among IXCs. The reason a customer might do this is for disaster recovery or for negotiating a better price among the carriers. For example, a customer may assign 50% of their traffic to Sprint and 50% to AT&T. It's all up to the customer.
Once the LEC determines to which IXC to send the call, it is sent to the IXCs point of presence (POP). The IXCs SCP must now determine where to send the call. When it comes to routing, the SCP is really the brains of the long distance network. The protocol used in this call control is known as Signalling System 7 (SS7). SS7 is a digital out-of-band method of transmitting information in the Public Switched Telephone Network (PSTN). SS7 is the protocol used to separate bearer control (the payload of the telephone call) from signaling control (setup and tear down of the call and services) in the AIN services network. Once the final determination of where the call is supposed to go is completed, the call is then routed to the subscriber's trunk lines. In a call center or contact center environment, the call is then typically answered by a telephone system known as an automatic call distributor (ACD) or
private branch exchange (PBX).
The subsequent routing of the call may be done in many ways, ranging from simple to complex depending on the needs of the owner of the toll-free number. Some of the available options are:
Time-of-Day (TOD) Routing. One of the simplest ways to influence the destination of the call is by using time-of-day routing. An example of using TOD routing would be a company with a call center on the east coast and a call center on the west coast. TOD routing would enable Follow the Sun routing. The east coast center opens first and calls are sent to that destination earlier in the day. As the time changes across the country, expanded coverage would be offered by the call center in the west.
Day of Week (DOW) or Day of Year (DOY) Routing. Depending on the day of the week and business practices, not all call centers operate 24x7. Some centers may be closed for weekends or holidays. DOW routing allows alternate routing for calls that arrive on specific days. DOY routing allows for alternate routing on fixed holidays (example December 25th).
Area Code or Exchange Routing. Toll-free traffic may also be routed depending upon the location of the caller. For instance, if a company has call centers in the north and in the south, they may express a preference to have their southern callers speak with people in the southern call centers. Companies may also wish to take advantage of the difference in interstate rates versus intrastate rates. For example, the cost of a telephone call across multiple states may be less expensive than a call within a state, and as a result, the ability to route a call originating in Michigan to a call center outside of Michigan can save a company substantial amounts of money.
Percentage Allocation Routing. If a company has multiple call centers, the company can choose to route calls across a number of call centers on a percentage basis. For example, an airline with ten call centers may choose to allocate 10% of all incoming traffic to each center.
All-Trunks-Busy Routing. If at a given time, a company's trunk facilities can no longer handle the incoming traffic, an alternate destination may be chosen. This assists companies handling unexpected call volumes or during crisis times.
Ring No Answer Routing. Some carriers have the ability to pull a call back into the network if the call is not answered. This provides for contingency routing for calls that ring and are not answered at the final destination.
Emergency or Disaster Routing. Companies usually have some type of disaster plan to deal with both natural (e.g. floods, fires and earthquakes) and man-made (e.g. bomb threats) emergencies. IXCs can provide alternate destinations should any of these situations occur.
Take Back and Transfer / Transfer Connect / Agent Redirect. If a company uses an ACD to facilitate the transfer, the ACD will remain in the call as long as the parties are on the phone. The drawback is that this uses up trunk capacity on the ACD (or VRU). This is called by a number of names including hair-pinning or tromboning. IXCs have the capability to allow a company to answer a call, provide a level of service, and then transfer the call to another location. These IXC features provide a level of transferring that is different from what is available via the ACD. There is usually a feature charge associated with this offering.
All of the above routing features are sometimes referred to as static routing features. These
routes are put in place and are not usually changed. If changes are required, a customer usually has several options to make changes. A customer can call the IXC directly via a special toll-free number to make changes, or a customer may be able to make changes through direct access to the network via a dedicated terminal provided by the IXC.
