Fake Number Generator

The fake number generator makes two kinds of placeholder numbers: fictional US phone numbers that end in 555-0100 to 555-0199, and random whole numbers in a range you set. Choose a type, set up to 100 numbers and press Generate; ID, card and bank numbers are not on offer.

What the fake number generator makes

Both types are drawn with the browser's cryptographic random generator, as described in how our randomness works. The phone numbers come from the same rules as the phone number generator, which explains the six formats in detail.

TypeExampleHow it is made
Fictional US phone number(647) 555-0158Three random area-code digits, the exchange 555 and a line number from 0100 to 0199, the range the North American Numbering Plan Administrator keeps for fiction.
Random whole number73One unbiased draw between your lowest and highest number, both included.
Column chart of 100,000 phone numbers from the fake number generator by line number: all 100 endings from 555-0100 to 555-0199 came up between 925 and 1,088 times, against 1,000 expected, and no number fell outside the reserved range.
The generator never leaves the reserved range, so every number it makes is one NANPA keeps for fiction.

Why there are no fake SSN, credit card or bank numbers

This page used to offer Social Security numbers, credit card numbers, IBANs and EINs alongside phone numbers. Those options are gone.

A number that is shaped like an identity document, a payment card or a bank account is useful for exactly two things: testing software, and pretending to be someone. The first has better tools, and we do not want to help with the second.

  • Payment cards: every payment provider publishes test card numbers that work only in its sandbox. See the links to Stripe, PayPal and Adyen.
  • IDs and bank details: use an obvious placeholder in your test data, such as the text “TEST-ID-0001”, rather than something that could pass for the real thing.
  • Everything else: the test data generator builds whole rows of names, emails, phone numbers and addresses that cannot belong to a real person.

Questions about the fake number generator

What happened to the SSN, credit card, IBAN and EIN options?

They were removed. Numbers that look like government IDs, payment cards or bank accounts can be misused whatever the page says about testing, so this site no longer generates them.

For card testing, use the test numbers your payment provider publishes; the test data generator links to the official lists from Stripe, PayPal and Adyen.

Are the phone numbers real?

No. Every number uses a line number from 555-0100 to 555-0199, which the North American Numbering Plan Administrator keeps as fictitious, non-working numbers.

What range can the whole numbers cover?

Any range of whole numbers, negative ones included, and both ends count. The range can hold up to 9,007,199,254,740,992 values. For no-repeat draws, sorting and a history of results, use the random number generator.

Can I get a fake number that passes a real check?

No. Nothing here is built to get past verification, and the phone numbers cannot receive calls or texts.
