RG Generator creates fictitious ID numbers in the format used by test systems, in the São Paulo state standard, with the check digit calculated, so you can fill out registrations and validate systems without having to use a real person's document. You choose the quantity, generate it with or without punctuation, and copy everything with one click. It is an online tool, free and without registration.
What is it
The ID Generator is a micro-tool that produces fictitious ID numbers in the format of the São Paulo General Registry (SSP-SP): 8 digits followed by a check digit, calculated from weights from 2 to 9 and the rest of the division by 11. This is the model most used as a reference in system tests, even when the registry is not specifically from São Paulo. The idea is simple: when a programmer, a quality analyst (QA) or a student needs to test a registration screen, they need a number that passes form validation. Typing someone else's real document is not a good idea, and inventing lucky numbers almost always gets stuck in validation because of the check digit.
This is where the tool helps. It generates, in seconds, one or several numbers that respect the expected structure and the check digit, allowing you to continue with the test. It is worth reinforcing an important point: the numbers created here are fictitious and are only used to test software. They do not belong to anyone, do not consult any official database and should not be used to impersonate anyone else. Using false document data to deceive someone or commit fraud is a crime provided for by law.
How to use
Using the generator is very quick:
- Set the quantity: choose how many numbers you want to generate at once, from 1 to 50.
- Choose the format: check the "With punctuation" box to receive the number in the pattern 00,000,000-0, or uncheck it to receive only the digits, without dots or dashes.
- Click on "Generate ID" to create the list of numbers on the spot, with the check digit calculated.
- Copy a specific number by clicking "Copy" next to it, or use the "Copy All" button when generating more than one, to take the entire list at once.
- Paste the numbers into the field of the system or form you are testing.
Everything happens directly in your browser, instantly, without having to install anything.
Tips
- Use the numbers only in test, approval or development environments, never in real registrations.
- If your system requires the number without punctuation, uncheck the "With punctuation" box before generating.
- Batch generating, with up to 50 numbers at once, use the "Copy All" button to quickly populate a spreadsheet or test database.
- Combine this tool with the CPF or CNPJ generator when you need to create a more complete test registration.
- Remember that a valid ID number in the format does not mean that it actually exists: it is just fictitious data for your software to process.
