Country Capital and Dial Code Reference

Overview

Before calling an overseas client you need the dialling code, before booking a cross-timezone meeting you need to know when their working day starts, and before shipping an international parcel you need the capital spelled correctly in English. That information usually lives in three different places. This reference collects it into one table of fifty-seven commonly used countries, giving the English and Chinese names, the capital in both languages, the international dialling code, the standard UTC offset and the resulting time difference against China at UTC+8. The search box matches country, capital or dial code as you type, the region filter narrows the list to one continent, and the whole table can be copied or exported as CSV for a meeting invitation template or a contact sheet.

Features

• Fifty-seven countries in one table with names in both languages, capitals, dial codes, UTC offsets and the gap to China
• Fuzzy search across country name, capital and dial code, so typing 86 or Japan both find the row
• Region filter covering Asia, Europe, the Americas, Africa and Oceania for continent level summaries
• Time differences shown with an explicit sign, where a positive value means the country is ahead of China
• The match count updates live and CSV export produces six columns for a spreadsheet
• Copy the current view as a compact list of country, code and offset for a group announcement

How to use

1. Type part of a country name, capital or dial code and the table filters immediately
2. Narrow the region dropdown when working continent by continent
3. Read the difference column, remembering that a positive figure means their clock is ahead of China
4. Watch for multi-digit codes such as +880 and +971, and drop the leading zero from the local number when dialling
5. Copy the compact list, or export CSV to keep the full six columns

Notes

• Offsets are standard time and exclude daylight saving, so European and North American summer months are one hour closer than shown
• A capital is not always the largest city: Australia lists Canberra rather than Sydney, and Turkey lists Ankara rather than Istanbul
• Drop the leading zero from the local number when dialling internationally, so London 020 becomes plus 44 20
• Countries on half or three-quarter hour offsets, such as India at plus 5:30, Nepal at plus 5:45 and Iran at plus 3:30, cannot be rounded to whole hours
• The United States and Canada span several zones; the table uses the capital zone, and a specific city needs its own offset
• Country counts and capital names change with administrative revisions, so formal documents should confirm against the latest official or carrier listing
• Dial codes identify a country, not a carrier, and a call still needs the correct national trunk prefix on the receiving side
• Offsets are standard time only: daylight saving shifts such as British summer time or US daylight time are not applied, so a country can be an hour off its summer value. Half-hour and three-quarter-hour zones such as India, Iran or Nepal are kept as written rather than rounded.
• A capital is not always the largest city, and some countries list more than one dialling code; the table keeps one row per country so filtering stays predictable.
