As of 2015, public pay phone locations can be determined by visiting websites such as PayPhone-Directory.org and PayPhone-Project.com and inputting the pay phone number into the site's Search tool. To date, there are no pay phone directories published by pay phone companies.
Both PayPhone-Directory and PayPhone-Project provide the user with the option to search by phone number as well as location. However, PayPhone-Directory only provides listing locations throughout the United States and Canada, while PayPhone-Project contains listings for other regions, including more obscure locations where available. Individuals compile these sites, and so they are updated irregularly, but remain the only traceable source for payphone locations.
