International Dialing Code Lookup

📖 Tool Introduction

International Dialing Code Lookup is an offline reference tool built for cross-border communication, foreign trade, overseas study and remote work. It bundles the dialing codes, UTC time offsets and capital cities of more than 60 major countries and regions into a single instantly searchable data table. When you need to place an overseas call, send an international text, book a meeting across time zones, or fill in an online form that asks for a country code, there is no reason to rummage through a heavy phone directory: just type a Chinese name, an English name, a dial code or even a capital city into the search box and the table filters the matches on the fly. The dial code is rendered in a highlighted monospace face for accurate copying, and the UTC offset lets you work out the local time of the person on the other end without mental arithmetic. All records are organized according to the ITU E.164 standard and bundled inside your browser, so no network request is ever made and the tool works instantly even offline. It stays comfortable on both desktop and mobile screens, and because nothing leaves your device it is a safe, high-frequency companion for anyone who deals with international contacts, partners or teammates on a regular basis. Whether you are a customer service agent, a freelance worker, a student or a traveler, this little table saves you the guesswork of guessing a country code before you dial. Keep this page handy whenever you schedule an overseas call, fill an international contact form, prepare a conference dial-in or check the local time of a team abroad, and the right calling code plus UTC offset is always one tap away.

⚠️ Notes

• Coding scale: dial codes follow ITU E.164; add the international prefix when calling for real
• Daylight saving: UTC offsets are standard-time values and may shift an hour in summer
• Reference set: the list covers common countries and regions, not the entire world
• Offline snapshot: the tool never connects online, so admin changes may lag behind
• Fuzzy matching: search works by substring, the more specific you type the more precise the hit
