Frequently asked questions
How does it work?
The NIC encodes the birth year and the day of the year (with 500 added for females). No data is looked up or sent anywhere.
Can it check if a NIC is genuine?
No — it only checks the format. It cannot verify a NIC with the Department of Registration of Persons.
Is NIC Number Decoder free?
Yes. NIC Number Decoder is completely free, with no sign-up, no watermark and no usage limits.
Is my data uploaded to a server?
No. NIC Number Decoder runs entirely in your browser. Your files and text never leave your device.
Does it work offline?
Yes. After Red Cat Tools has loaded once, this tool keeps working without an internet connection. You can also install Red Cat Tools as an app.
