About Random Nr's Account Number Generator
The random account number generator creates account numbers of any length for test systems and demo data sets. Set the digit length and how many you need, and Random Nr returns numbers that look right for a form or a database seed while being tied to no real account, which keeps your test data safe to share.
Bank account number lengths by country
Bank account number length is not universal, which is exactly why test data needs to cover several widths. These are common national formats.
| Where | Typical account number length |
|---|---|
| United States | 8 to 12 digits |
| United Kingdom | 8 digits, plus a 6 digit sort code |
| Australia | 6 to 10 digits, plus a 6 digit BSB |
| India | 11 to 16 digits |
| Canada | 7 to 12 digits, plus transit and institution |
Because the same field must accept many of these, generating a spread of lengths is the fastest way to test that a form neither truncates a long number nor rejects a short one.
Why these test account numbers are safe
Every number here is independent random digits with no checksum and no bank routing, so it cannot correspond to a real account. That is the point: test data should look right and be inert. A real bank number in a test system is a data protection risk, while a random one carries none, and if a checksummed format is what you are testing, the IBAN generator produces valid ones instead.
Why these are plain digits with no checksum
This tool deliberately stops at random digits. Real account systems layer on sort codes, routing numbers and check digits that vary by country, none of which a generic account number should invent. When you need a full, checksum valid international number, the IBAN generator builds one that passes validation.

Frequently asked questions
What lengths can I choose
Eight, ten, twelve or sixteen digits, covering the common shapes of account numbers across systems.
Are these real bank accounts
No. They are random digits for testing and demos, not linked to any real account.
Can I generate many at once
Yes, up to 500 at a time, ready to copy or export as a CSV.
Do they include a check digit
No. For a checksummed format such as a bank IBAN, use the IBAN generator instead.
Is it free
