International Calling Codes & Time Assistant

Find the Right International Country Code

Making an international phone call requires more than just dialing the digits. You need the correct routing prefixes to connect the call, and you need to ensure you aren't waking someone up in the middle of the night. Our International Calling Codes directory provides a fast, searchable database of every official country calling code (ISD) for all 240+ countries and territories worldwide, completely eliminating the guesswork from cross-border communication.

Formatting an international call properly is a simple three-step process. First, you need an exit code to get out of your own country's phone network (on a smartphone, just hold down the '0' key to type a '+', which works universally). Second, you type the country code you found in our directory. Finally, you dial the local phone number. For example, to call London from the US, you would dial +44, followed by the local UK number.

The most important feature of this directory isn't just the dialing codes—it is the live clocks. Next to every country code, we display the current, atomic-calibrated local time in that nation's capital. When you are coordinating global logistics or calling overseas family, a quick glance at this page ensures you only ring their phone during appropriate daylight hours.
