Pincode API guide

Build PIN Code Autocomplete

Build a responsive PIN code or post office search experience.

Keep search payloads small

The website loads only the small amount of search data needed for the query, helping the search remain responsive on mobile and desktop devices.

Debounce user input

Wait briefly after typing before starting a search, cancel obsolete requests and avoid repeating the same request unnecessarily.

Limit results

Show a small relevant result set first. This reduces rendering work on mobile devices and makes keyboard navigation easier.
