A collect call in the USA and Canada or reverse charge call in the UK and other countries (or calling collect) is a telephone call in which the calling party wants to place a call at the called party's expense. In the past, collect calls were only possible as an operator-assisted call, but with the introduction of computer-based telephone dialing equipment, it is now possible to place a collect call without using an operator, which is called International Freephone Service (IFS) as opposed to Home Country Direct (HCD). Several companies offer services to place collect calls that compete with local service providers. When the operator's number is globally unique, i.e. it does not depend on the caller's country, it is called Universal International Freephone Number (UIFN).
While Mother's Day has the highest number of phone calls, the most collect calls are made on Father's Day.[1][2][3][4]
Other forms of paid communication, such as telegrams and mail, could also be sent "collect".
a collect call is made when the charges are billed to the called telephone number. A collect call is an operator assisted call. Authorization must be obtain from the person being called before the call is allowed to proceed.
