Everything it can do

Recognises the country from any international phone number and its dialing code.

Live Local Time

Shows the current time in the number’s country, updating in real time.

Capital & Currency

Displays the country’s capital city and official currency.

Dialing Code Reference

See the international dialing code and number formatting for the country.

Instant & Offline

Works instantly from a built-in dataset — no API calls, no network needed.

Numbers never leave your browser. Nothing is sent anywhere.

State & Region Detection

Reads the area/state code to pinpoint the region and show its exact local time — essential for countries with multiple time zones like the US, Australia and Canada.

Frequently asked

Where can I get it?
It’s available now — free on the Chrome Web Store. Click “Add to Chrome” above to install.
Does it call or text the number?
No. DialWhere only looks up information about the number’s country — it never dials or messages anyone.
Do I need to enter the country code?
Yes — include the country code (e.g. +44, +1) so DialWhere can identify the correct country.
Is my data private?
Completely. Lookups happen entirely on your device using a built-in dataset; nothing is sent to a server.
Does it handle countries with multiple time zones?
Yes. DialWhere reads the state/area code to detect the region, so a California number and a New York number show their own correct local times — not just a single country time.
