PrivacyFrequently asked questions
Can I look up a full Canadian postal code or UK postcode?
The provider has partial Canadian coverage. The search uses the first three characters, for example K1A. UK results use the outward code, for example SW1A. These are area-level results.
Why is my city or country missing?
The tool uses the countries and territories listed by Zippopotam.us. City searches require a state or province code and may miss locations without their own postal code records.
Will the CSV keep leading zeros?
The exported text preserves leading zeros. If your spreadsheet changes 00501 to 501, import the postal code column as text.
