Random Phone Number Generator

How to generate random phone numbers

1. Keep "Fictional (safe)" selected unless you have a specific reason not to. These numbers are reserved and cannot be assigned to anyone.
2. Choose a region. US & Canada uses 555-01XX with a random area code. The UK options use Ofcom's drama ranges for mobiles, London and Manchester, or mix them.
3. Set how many you need, from 1 to 1,000. Leave No duplicates on when the numbers must be unique, such as primary keys or seed users.
4. Pick a format: national, dashes, dots or E.164, and tick Include country code for international style. Changing the format re-formats the same numbers.
5. Copy or download. Copy one number, copy all, or download a .txt (one per line) or a .csv with the formatted number, the E.164 form, country and type.

The fictional ranges this tool uses

In North America, the numbering administrator (NANPA) reserves 555-0100 through 555-0199 for fictional use in every area code. Other 555 numbers are not all fake: 555-1212 has long been directory assistance, and some 555 lines were assigned to businesses. That is why the tool only ever uses the 0100 to 0199 block. The area code is random but follows the rules for geographic codes: it never starts with 0 or 1, is never a service code like 211, 411 or 911, and is never a toll-free code like 800 or 888.

In the UK, Ofcom publishes blocks of numbers for use in films, TV, radio and books. This tool uses three of them: 1,000 mobile numbers starting 07700 900, 1,000 London numbers starting 020 7946 0, and 1,000 Manchester numbers starting 0161 496 0. With duplicates turned off, you can get at most 1,000 numbers from a single UK range.

Output formats

E.164 is the international standard used by most APIs, SMS gateways and databases: a plus sign, the country code, then the number with no spaces or trunk zero. If you are testing a phone field that normalises input, generate the same list in several formats and check that every version is stored as the same E.164 value.

Fictional vs valid format

The Valid format (may be real) mode builds US numbers that follow every structural rule: a valid area code, an exchange that starts with 2 to 9 and is not an N11 service code, and any four-digit line number. That is useful for testing validators that reject 555 numbers, but it means many results are real people's phones. Never call or text them, never load them into a dialer, SMS campaign or marketing tool, and do not publish them. For anything that could actually send a message, stay with the fictional ranges.

Use cases

• Seeding databases for development and staging with realistic, unique contact data.
• QA and automated tests for sign-up forms, phone input masks and libphonenumber validation.
• UI mockups and screenshots where a real-looking number reads better than 000-000-0000.
• Fiction, games and film props, the original reason these ranges exist.
• Training material and documentation where a sample number must not belong to anyone.

Pair the numbers with names from the Fake Name Generator to build complete test profiles, and use the UUID Generator for matching IDs.
