About Airport Code Lookup
What is Airport Code Lookup?
Airport code lookup is a tool that helps travelers quickly identify global airports. IATA (International Air Transport Association) assigns a unique 3-letter code to each airport, widely used in flight booking, baggage tags, and flight information displays. Through airport code lookup, you can enter a code to find the airport name and city, or enter a city name to find the corresponding airport 3-letter code. Currently, over 200 major international airports worldwide have unique IATA codes. Mastering these codes can make your travel smoother and more efficient.
Why do you need airport code lookup? Because many cities have multiple airports. For example, Beijing has Capital International Airport (PEK) and Daxing International Airport (PKX), while Shanghai has Pudong International Airport (PVG) and Hongqiao International Airport (SHA). If you only remember the city name but not the specific airport code, you can easily make mistakes when booking flights or filling in baggage information. The airport code lookup tool includes a complete airport code reference table, supports fuzzy search and continent filtering, helping you accurately locate your target airport.
How to Use City Airport Code Lookup?
Using city airport code lookup is very simple. First, enter the information you know in the search box, which can be an IATA 3-letter code (e.g., PEK), a city name (e.g., Beijing), or an airport full name (e.g., Capital Airport). Second, if you need to narrow down the results, you can click continent filter buttons to select Asia, Europe, North America, and other regions. Third, view the results list, where each entry displays the airport code, full airport name, city, and country. You can also copy individual codes or all search results with one click.
For frequent business travelers, it's recommended to save commonly used airport codes to your notes. For example, for international flights departing from China, PEK (Beijing Capital), PVG (Shanghai Pudong), CAN (Guangzhou Baiyun), and HKG (Hong Kong International) are the most commonly used codes. Through city airport code lookup, you can quickly confirm the exact code of your connecting airport, avoiding travel delays caused by code confusion.
Airport Code Lookup and Airport Code Reference Table Knowledge
The airport code reference table is the global airport code database officially maintained by IATA. Each 3-letter code is strictly assigned to ensure global uniqueness. Interestingly, some codes appear unrelated to city names because airport codes may originate from historical names. For example, Chicago O'Hare International Airport's code is ORD, derived from the airport's former location name, Orchard Field. Understanding this background knowledge can help you better memorize airport codes.
IATA 3-letter codes and ICAO 4-letter codes are two different systems. IATA codes serve passengers, mainly used for flight booking and baggage tags; ICAO codes serve aviation professionals, used for air traffic control and flight plans. Ordinary travelers only need to focus on IATA 3-letter codes. The airport code lookup tool focuses on IATA codes, providing the most practical travel reference information.

Airport Code Lookup FAQ
❓ What's the difference between IATA and ICAO codes?
IATA codes are 3 letters, mainly used for flight booking and baggage tags (e.g., PEK). ICAO codes are 4 letters, mainly used for air traffic control and flight plans (e.g., ZBAA). Ordinary travelers only need to focus on IATA codes. The airport code lookup tool provides IATA 3-letter codes, fully meeting daily travel needs.
❓ Why do some codes seem unrelated to city names?
Some codes come from historical names (e.g., ORD = Chicago O'Hare, formerly Orchard Field), while others are changed because the original code was already taken (e.g., BJS is no longer Beijing's city code, replaced by PEK). Checking the airport code reference table can help you understand the complete origin and historical background of each code.
❓ How to look up international airport 3-letter codes?
Using this tool's international airport 3-letter code lookup feature, you can enter a city name or airport name in the search box, and the system will automatically match all relevant airports and display their corresponding 3-letter codes. For example, entering "Tokyo" will show both NRT (Narita International Airport) and HND (Tokyo Haneda Airport). It supports mixed searches in Chinese, English, and codes for highly efficient lookups.
❓ What search methods does airport 3-letter code lookup support?
Airport 3-letter code lookup supports three search methods: first, directly enter a 3-letter code (e.g., LAX) to find airport information; second, enter a city name (e.g., Los Angeles) to find all airport codes in that city; third, enter an airport full name or keyword (e.g., Kennedy) for fuzzy matching. Combined with the continent filter, you can quickly locate target airports across six continents.
❓ Which countries and regions' airports are covered in the airport code reference table?
The airport code reference table covers major international airports in over 90 countries and regions across six continents, including China (including Hong Kong, Macau, and Taiwan), Japan, South Korea, Singapore, Thailand in Asia; the UK, France, Germany, Italy in Europe; the US and Canada in North America; as well as major aviation hubs in Oceania, South America, and Africa. The data is continuously updated to ensure accuracy and timeliness.
