台灣3+2郵遞區號查詢

The 3+2 Postal Code Lookup for Taiwan offers a straightforward method for users to retrieve postal codes by entering complete address information. This service is particularly convenient as it automatically converts addresses in the Taipei County area to the New Taipei City designation, with similar adjustments for Taichung County, Tainan County, and Kaohsiung County.

It is important to note that entries must be in traditional Chinese characters, and an active internet connection is required for functionality. Incomplete address entries may result in inaccurate postal code outputs. Additionally, users should ensure that numbers preceding street names and types (such as lane and section) are entered using half-width characters to avoid errors.

This service utilizes the API from zip5.5432.tw.
