Common upload errors
Using an old RRB size guide
Check the CEN because RRB workflows and size ranges can change between recruitments.
Signature is faint after compression
Rescan with darker ink and crop the blank paper before resizing.
Camera capture is unavailable
Allow camera permission, update the browser, and retry with stable internet.
Frequently asked questions
Are all RRB signature limits identical?
No. Use the size and dimension values in the active CEN and portal instructions.
Why is there no scanned-photo preset?
Recent RRB flows may capture the photograph live. The active CEN determines the actual workflow.
Not sure whether the file is ready?
Run the downloaded output through the Universal Form File Checker and compare it with the active official instructions before submission.
