# Mobile Number - **Website:** - **Primary alias:** `mobilenumber.org` ## Description MobileNumber.org is a global reference for understanding mobile numbering systems and looking up phone number information across countries. Its free search tool helps users check mobile number formats, international dialing codes, and the network operator a number’s prefix was originally assigned to, using data compiled from official national numbering plans and telecom regulator publications. Visitors can search by mobile number, prefix, or carrier, browse operator directories, and explore country-specific numbering information. For countries where number prefixes indicate geography rather than a carrier, the site provides city and area code references with correctly formatted example numbers. MobileNumber.org also explains key topics such as national and international number formats, carrier prefixes, and mobile number portability, noting that a prefix may not identify a subscriber’s current network. The site covers countries worldwide and makes its content available in 14 languages. Searches require no signup, and the site states that searched numbers and prefixes are not stored against users. MobileNumber.org is an independent information resource and is not affiliated with telecom operators or regulators. ## Industries - 🗺 Reference Materials - 🗺 Public Records and Directories _(under Reference Materials)_ - 🖥 Computers Electronics and Technology ## Logos & icons - logo _(primary)_ — PNG — [download](https://cdn.brandfetch.io/idJjhxwRgg/w/512/h/512/theme/light/logo.png?c=1bxid64Mup7aczewSAYMX&t=1791199314704) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Danube | #71a5d9 | accent | | Mirage | #1d293d | dark | | White | #ffffff | light | ## Fonts - var(--font-sans) — asset _(custom)_ - var(--font-sans) — 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._
