This numpad tester isolates the numeric keypad for a focused diagnostic: digits 0 through 9, the four math operators (+, -, *, /), the decimal point, Enter, and Num Lock. Press each key and it's marked as tested on a compact numpad diagram, with a running tested-key count so you can confirm the entire keypad works. It's especially useful for accountants, data-entry professionals, and anyone who relies heavily on the numpad for rapid numeric input - a single unresponsive digit can be surprisingly disruptive to that workflow, and this tool finds it fast.
Features
- Dedicated numpad-only diagram (0-9, operators, Enter, Num Lock)
- Persistent tested-key marking with progress counter
- Key name and code details for each press
- Faster than checking the numpad within a full keyboard test

- 100% private - everything runs locally in your browser, nothing is uploaded
- Purpose-built for numpad-heavy workflows like data entry and accounting
- Completely free with no signup, installs, or usage limits
Frequently asked questions
My numpad isn't responding at all - what should I check first?
Confirm Num Lock is enabled first (many numpads produce navigation codes instead of digits when Num Lock is off), then retest.
Does this test laptop numpads or numpad emulation?
Yes, it works with any input that generates standard Numpad* key codes, including dedicated numpads and some laptop Fn-based numpad emulation.
What does the Num Lock key show when toggled?
Pressing Num Lock registers like any other key here; toggling its actual on/off state is handled by your OS separately from this test.
