Fax Number Generator
"Fax number generator" means different things to different people. Some want a number to test their machine. Others need a fictional number for a script or a placeholder for code. Here's what you're actually looking for — and where to find it.
Need a fax number to test your machine?
If you're trying to confirm that your fax machine can send, you need a real number that accepts faxes and shows you the result. That's exactly what Faxbeep does — pick a number, send a fax, and view it online within minutes.
For a step-by-step walkthrough, see our fake fax number for testing guide.
Troubleshooting a fax that isn't working?
If your fax machine is failing to send or you're getting error codes, the issue is usually your line, your settings, or VoIP incompatibility — not the number you're dialing. Our dummy fax number page walks through common error codes, send-vs-receive testing, and a diagnostic checklist.
Why you shouldn't dial a random fax number
When people search for a "fax number generator," they sometimes mean they want to pick a random number to test with. This doesn't work — most numbers aren't fax lines, you can't verify delivery, and you might fax a stranger. Read why random fax numbers are a bad idea and what to do instead.
Fax numbers for TV, film, and advertising
Television shows, films, and advertisements need fax numbers (and phone numbers) that look real but don't belong to anyone. Regulators in several countries reserve number ranges specifically for fictional use in media.
United States (555 numbers)
In the US, the range (XXX) 555-0100 through (XXX) 555-0199 is reserved for fictional use across all area codes. If you've ever seen a phone number in a movie, it was probably a 555 number. These numbers are never assigned to real customers, so they're safe to use on screen, in print, or in advertising.
United Kingdom (Ofcom drama numbers)
Ofcom reserves entire blocks for use in TV, radio, and film:
| Type | Number range |
|---|---|
| Fictional area | 01632 xxx xxx |
| London | 020 7946 0xxx |
| Mobile | 07700 900xxx |
| Freephone | 0808 157 0xxx |
| Premium rate | 0909 879 0xxx |
| UK-wide | 0306 999 0xxx |
These are published by Ofcom specifically so that productions don't accidentally use a real person's number.
Australia (ACMA fictional numbers)
ACMA reserves fictional number ranges for dramatic use:
| Type | Number range |
|---|---|
| Geographic | (0x) 5550 xxxx |
| Mobile | 0491 57x xxx |
| Premium | 1900 654 321 |
| Freephone | 1800 160 401 |
Details are published by the ACMA.
Print and design mockups
If you need a fax number for a business card template, brochure mockup, or design comp, use a fictional number from the ranges above. They look realistic, won't ring anyone's phone, and are recognized by anyone in the media industry.
Developer tools for generating fax numbers
If you're seeding a database or populating test fixtures, libraries like Faker can generate phone-formatted strings that pass validation without being real numbers.
// PHP (fakerphp)
$faker = Faker\Factory::create();
$faker->phoneNumber; // "+1-555-258-4587"
# Python (Faker)
from faker import Faker
fake = Faker()
fake.phone_number() # "001-553-718-2824x271"
// JavaScript (fakerjs)
import { faker } from "@faker-js/faker";
faker.phone.number(); // "555-329-1704"
These numbers are for database seeding and development only — they don't connect to real fax lines. If you need to test actual fax transmission, see our fake fax number for testing page.
FAQ: Common Questions About Our Fax Testing Service
No. Fax numbers are real telephone lines connected to fax equipment — they can't be "generated" the way email addresses can. If you need a number to send a test fax to, use a free test service like Faxbeep.
Not through Faxbeep — we provide test numbers for verifying that your fax machine works. If you need a temporary number to receive faxes, online fax services like eFax or Fax.Plus offer short-term plans. Visit our home page to learn more about what Faxbeep does.
They overlap, but people mean different things. A fake fax number usually means a test number to verify your machine works. A dummy fax number often comes up when troubleshooting a machine that isn't working. A random fax number is what people try when they don't know a real number to test with — it doesn't work and can cause problems.
No. Numbers shown in TV shows, films, and ads come from reserved ranges (like 555 numbers in the US) that are never assigned to real customers. They exist specifically so media productions don't accidentally show someone's real number.
