A little CLI utility that calculates and lists all of the numbers between 1 and 1,000,000,000. The algorithm used runs with complexity of O(√n) and took about 27 minute 11 seconds. There's also a link to just download its output (50 megs compressed with 7z, 502 megs uncompressed).
In multiple languages.
NNIRR has gathered a list of national, state and local Immigration Hotlines. See our list below for hotlines where you can:
- report raids in your area
- seek help if being detained or at risk of being deported
- report missing migrants
We will update these as new numbers become available.
This site contains local calling, area code, and prefix information for Canada, the United States of America, and other countries which are part of the North American Numbering Plan.
They have their own e-mail list, interestingly.
PhreakScan is the premiere repository of interesting telephone numbers on the net. By phreaks, for phreaks.
What the various sets of numbers are and how they relate to one another.
Transform any image into a prime number that looks like the image if glanced upon from far away.
A Voip Wardialer for the phreaking of 2020.
Generate random phone numbers for all countries using the mobile phone generator. These numbers are fake, but they are built using the validations of telephone numbers.
For a price of a cinema ticket a month we offer a physical phone number. All your messages are encrypted with your personal key that we cannot access. Has a REST API you can send and receive messages through. They can store contact lists for you, deniably they claim. Accepts cryptocurrency for payment.
A visual directory, source map, and explorer for OSINT sources and utilities. If you're not sure what you need or what to try, browse the categories until you find something that looks useful.

A Python module for formatting things in a human-friendly way. Parses and formats numbers, file sizes, pathnames, lengths of time. Includes timer functionality. Implements lists of options for user input. ANSI friendly.
A website dedicated to helping people navigate mazes of IVR systems to talk to a human operator.
Convert any number into different numerical bases, such as binary, trinary, octal, and base-20.
A website about randomness, (pseudo-)random number generators, and cryptographic entropy. Contains discussions of these topics as well as some online RNGs to play with.
Along with NIST SP800-22rev1 (statistical analysis of pseudo-random number generators), the Statistical Test Suite can be used to actually perform the tests outlined in this document. Runs under Windows, Linux, and Mac OSX. Written in C.
A method for distributing cryptographic entropy in the form of numerical values to systems that need it. Collects entropy from other systems and hashes it into the pool. While I can't vouch for how much entropy is in those values it seems interesting to experiment with.
The primary instance of the NIST Randomness Beacon. Has a REST API for access (which is going to change). Pull random numbers out of it but don't trust them because you didn't generate them yourself.
