Validate Indian Postcodes API

Hosted on ApyHub

What it does

The Pincode API checks whether an Indian PIN code is real. Send a six-digit pincode and get back true or false. Spaces are ignored, so 110 001 and 110001 both work.

Use it to stop bad addresses at the point of entry. Checkout forms. Signup flows. CRM imports. Bulk address cleanup on data you inherited. Catching a wrong pincode before an order ships saves a failed delivery and a support ticket.

The response is deliberately small. One boolean, nothing to parse. That makes it cheap to call on every keystroke or on form submit, and easy to drop into a validation chain next to your email and phone checks.

It tells you the pincode exists. It does not tell you which city or state it belongs to, or whether the rest of the address matches it. If you need the full address verified, use the Address Validation API. Shipping outside India too? The UK Postcode API works the same way.
