# Local calling guide - **Website:** - **Primary alias:** `localcallingguide.com` ## Description Local Calling Guide is an online reference for telephone numbering and local calling information across Canada, the United States, and other countries within the North American Numbering Plan. It helps users explore area codes, telephone prefixes, rate centres, switching information, and related telecommunications data. Search tools support lookups by area code or prefix, rate centre, switch CLLI code, and company name, while activity listings provide information about local calling area changes by date. The site also offers practical tools for telecommunications research and call planning. Its Local Call Finder calculates the rate distance between two points and indicates whether a call may qualify as local. Users can consult information on dial-around carrier identification codes, as well as an experimental XML query interface for dial-plan data. Reference lists cover regions, area codes, Local Access Transport Area codes, and Canadian Local Interconnection Region codes. Additional resources include telecom and tariff links, a discussion group, and answers to seldom-asked questions. ## Industries - 🗺 Reference Materials - 🗺 Public Records and Directories _(under Reference Materials)_ - 🖥 Computers Electronics and Technology - 🖥 Telecommunications _(under Computers Electronics and Technology)_ ## Logos & icons - logo _(primary)_ — PNG — [download](https://cdn.brandfetch.io/idcDPkZ2bM/w/126/h/87/theme/dark/logo.png?c=1bxid64Mup7aczewSAYMX&t=1793136911996) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Gallery | #eeeeee | accent | | Japanese Laurel | #008001 | dark | | Manhattan | #f7cf8f | light | ## Fonts - helvetica — asset _(custom)_ - sans-serif — asset _(custom)_ --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
