Country codes come in at least four flavours and no two systems agree on which to use. An HTML lang attribute and a ccTLD want the two-letter alpha-2, a passport or a football scoreboard uses alpha-3, a UN dataset uses the three-digit numeric code, and a phone field wants the ITU dialling code. This table carries all of them for every officially assigned ISO 3166-1 entry, searchable by any one of them or by name. Paste a column of codes from a spreadsheet and it converts the lot in one pass, flagging anything it cannot match, and the whole table exports as CSV or JSON.

How to use the Country Code Lookup
Type a country name or any of its codes into the search box
Or switch to the convert tab and paste a list of codes
Filter by region to narrow a long table
Copy the rows you need, or download them as CSV or JSON
Example
Input
DE
Output
DE · DEU · 276 · +49 · .de · Germany
One row carries every identifier a form, an API or a dataset is likely to ask for.
Common errors & troubleshooting
A code from an old dataset is not in the table. — It may have been withdrawn. Codes such as AN for the Netherlands Antilles and CS for Serbia and Montenegro were retired when the countries changed, and ISO does not reassign them for fifty years.
The United Kingdom's ccTLD does not match its alpha-2 code. — It is the well-known exception. The ISO code is GB but the domain is .uk, because the domain was assigned before the standard settled. Both are shown so neither surprises you.
Several countries share the same dialling code. — That is correct for the North American Numbering Plan, where more than twenty countries share +1 and are separated by area code. Those area codes are shown after the plus-one.
A name in the table does not match the one used locally. — The table carries the short English name from the standard, which is sometimes formal — Korea, Republic of rather than South Korea. Search matches on fragments, so either spelling finds it.
Frequently asked questions
What is the difference between alpha-2 and alpha-3 country codes?
Alpha-2 is the two-letter code used by ccTLDs, HTML lang attributes and most web APIs. Alpha-3 is the three-letter form, which is more readable to a person and is used by the UN, FIFA, ICAO and many financial file formats.
What are the numeric country codes for?
They are language-independent, so they survive translation and script changes, and they suit systems that store codes as numbers. UN statistical datasets and several customs formats use them as the primary key.
Is XK a valid code for Kosovo?
Not officially. Kosovo has no ISO 3166-1 assignment, so XK is a user-assigned code that the European Commission and several payment networks adopted by convention. It is not in this table for that reason.
Why is the ccTLD usually the same as the alpha-2 code?
Because ccTLDs were assigned from the ISO list in the first place. The handful of exceptions come from domains that predate the assignment or from territories with no delegated domain at all.
Do these codes cover territories as well as countries?
Yes. ISO 3166-1 covers dependent territories and areas of special interest, which is why Guernsey, Réunion, Antarctica and the British Indian Ocean Territory all have their own entries.
