In North American NANP telephone system, anonymous call rejection (ACR) is a landline calling feature that screens out calls from callers who have blocked their caller ID information. It is often free and included with caller ID on landlines, but it may be available separately from the local telephone company. ACR is not available in all areas.
When ringing a line with anonymous call rejection, incoming callers with caller-ID blocking enabled will hear a message stating that the line does not accept calls from callers who block their number. Callers who have blocked their caller ID information will then hear a recording instructing them not to block their caller ID when calling that line.
This feature is not available from most cellphone services with caller ID, such as Sprint, T-Mobile USA or AT&T. Verizon Wireless does provide this service, but ACR prevents dialing a feature code or successfully calling customer service. Verizon Wireless does not currently provide blocked or anonymous call rejection, but customers may block up to five specific numbers at MyVerizon.
