Set the minimum less than or equal to the maximum.

Quantity

Pick how many values to create per run. Set a number from 1 to 10.

Generate

Select Generate to create your list. The new list replaces any earlier results.

Copy to Clipboard

Select Copy to Clipboard to copy the full list as plain text. Some browsers block clipboard access. If that happens, select the results and copy by hand.

What you get

The output shows under Generated Numbers. Each item appears on a new line. Here is how to read each type.

• United States Phone Number. It uses a real area code list and a valid layout.
• Social Security number. It avoids 666 in the area part and zero only blocks.
• Credit card number. It follows the Luhn rule and uses real brand prefixes.
• International Bank Account Number for Germany. It shows DE, two digits, and grouped numbers for bank and account.
• Employer Identification number. It shows two digits, a hyphen, and seven digits.
• Random Integer. It picks a whole number between your minimum and maximum.

Use cases

• Fill signup forms without real data.
• Seed demo apps with readable numbers.
• Create test fixtures for unit and end to end tests.
• Mask logs before sharing with a team.
• Build screenshots for docs and guides.
• Train support staff on workflows with safe data.

Format details and notes

United States Phone Number

Area codes follow a real list. The middle block starts at 200. The last block has four digits. The format looks like a standard United States number.

Social Security number

The format is three, two, and four digits with hyphens. The area part avoids 666. Group and serial parts start at 01 and 0001. These values exist for tests only.

Credit card number

Brand prefixes include Visa 4, Mastercard 51 to 55, American Express 37, and Discover 6011. The last digit follows the Luhn checksum. Visa, Mastercard, and Discover use sixteen digits. American Express uses fifteen digits. Payment networks will reject these numbers in real charges.

International Bank Account Number for Germany

It shows DE plus two digits, then a bank code and an account number. Spaces improve reading. The check digits use a simple method here. Some bank systems will mark these as invalid.

Employer Identification number

The format is two digits, a hyphen, and seven digits. It matches the common layout used in the United States.

Random Integer

The range includes both ends. The generator alerts if minimum exceeds maximum. Use this to hit boundaries and edge cases in your code.

Limitations and ethics

• Use this tool for lawful testing and demos.
• These values simulate format and checks. They do not open accounts or lines.
• Credit cards pass the Luhn test only.
• International Bank Account Numbers use a simple check. Many systems will fail them.
• Some random outputs can match real data by chance. Use in safe test spaces only.
• The generator runs in your browser. Copy to clipboard depends on browser settings.
• The Quantity field creates up to ten values per run.

Tips for better testing

• Use Quantity to create small batches for stress tests.
• Mix types to test full signup and checkout flows.
• For edge checks, set Minimum equal to Maximum.
• Save outputs as fixtures and reuse them across tests.
• Use phone, SSN, and EIN formats to catch improper validation.
• Use the copy action and paste into Postman or Cypress data files.

Frequently asked questions

Are these numbers real?

Will the fake credit cards work in a payment gateway?
