Random US Phone Number Generator
Generate random US phone numbers by area code. Fictional mode uses the 555-0100 to 555-0199 range, which is reserved and safe for test data.
Numbers are generated in your browser and are never stored or sent anywhere.
How US phone numbers work
A US number has 10 digits after +1: a 3-digit area code, a 3-digit exchange and a 4-digit line number, as in (212) 555-0143. Neither the area code nor the exchange can start with 0 or 1, and three-digit service codes such as 411 and 911 are not used as exchanges.
Only 555-0100 to 555-0199 is officially reserved for fiction and testing. Other 555 numbers look fake, but they are not reserved, so this tool does not use them in fictional mode.
Sample fictional US numbers

Fictional vs valid-format numbers
| Mode | Numbers used | Good for |
|---|---|---|
| Fictional | Only ranges a regulator has reserved for film, TV and testing | Test data, mock-ups, screenshots, films and games. Not assigned to subscribers. |
| Valid format | Any number allowed by the numbering plan | Testing validation libraries such as libphonenumber. May reach real subscribers. |
Why a random number will not verify an account
Sign-up forms send a one-time code by SMS. With a random number, that code goes to whoever owns the line, or nowhere. To get past phone verification you need a number whose messages you can read:
- Free phone numbers: public inboxes for USA, UK and Canada. Anyone can see the messages, so they suit quick tests only.
- Temporary phone numbers: a private number for one code, charged only if the SMS arrives.
- Receive SMS online: rentals that keep the same number for days or weeks.

Frequently asked questions
What is a random US phone number for testing?
Use a fictional number such as (212) 555-0143. The 555-0100 to 555-0199 range is reserved, so no subscriber has it, and any area code works.
Can I get a random US number from a specific area code?
Yes. Pick the area code in the list, such as 212 for New York or 415 for San Francisco. Every number generated will use it.
Are the generated phone numbers real?
In "valid format" mode the numbers follow the real numbering rules, so some of them may be assigned to real people. Do not call or text them. In "fictional" mode you only get numbers from ranges a regulator reserves for films, TV and testing, which are not given to subscribers.
Can I use a random phone number to receive a verification code?
No. A generated number is just digits: you cannot read SMS sent to it, and a code sent there would go to whoever owns the line, or nowhere. To receive a code, use a number you can actually read, such as a free public number or a private virtual number from SMS Pin Verify.
What is a fake phone number for testing?
Developers use fictional numbers to fill forms, seed databases and test input validation without contacting anyone. Use the fictional mode of this generator for that, since those ranges are reserved and safe.
Which countries have fictional numbers?
The USA, Canada, UK, Australia, Ireland, Germany, France and Sweden have published ranges, and this tool uses them. We found no usable published range for the other countries, so they offer format-only numbers with a warning.
What format are the numbers in?
You can choose national format, such as (212) 555-0143 or 07700 900123, international E.164 format, such as +12125550143, which is what most APIs and databases expect, or plain digits.
