Always Include the Country Code

When addressing international shipments, combine the postal code with the ISO country code for maximum delivery accuracy across borders.

After looking up a postal code, cross-reference with your shipping carrier's own validation tools to confirm deliverability and zone rates.

Use Full Format for International

Validate Customer Addresses

Integrate postal code validation into your checkout flow to catch typos early, reducing failed deliveries and chargebacks.

Map to Customs Zones

Use postal codes to determine the correct customs district or import processing center, especially important for bonded warehouse operations.

Keep Your Database Updated

Postal codes can change. Periodically verify your stored postal data with official postal authority sources to avoid using outdated codes.

Frequently Asked Questions

Everything you need to know about postal codes and how to use this finder tool.

A postal code (also called a ZIP code in the US, postcode in the UK, or postal index number in India) is a series of letters, digits, or both assigned to specific geographic areas. Postal codes help postal services and couriers sort and deliver mail and packages efficiently. They are critical for international shipping, customs clearance, and e-commerce fulfillment.

Our database currently covers 30+ countries including the United States, United Kingdom, Canada, Australia, Germany, France, China, Japan, India, Brazil, Mexico, Italy, Spain, Netherlands, Sweden, Norway, Denmark, Finland, Poland, Russia, South Korea, Singapore, Malaysia, and Thailand. We regularly add more countries based on user demand.

If your search doesn't return results, try broadening your search: remove the country filter, try a nearby major city, or check the spelling. Some rural or newly developed areas may not yet be in our database. In those cases, we recommend checking the official postal authority website for the most up-to-date information.
