# What is a ZIP Code?

A **ZIP code** (also known as a **postal code, postcode, or PIN**) is a combination of numbers and/or letters used to help sort and deliver mail. But on ZoomBucks, it serves another important purpose.

When you enter your ZIP code in your profile, it helps us — and our survey providers — match you with **relevant surveys** that are targeted to your **location and demographic**.

### Why This Matters:

* Survey walls like **CINT** use your ZIP code to offer surveys that are **more accurate and better suited to your background**.
    
* It increases your chances of **qualifying for surveys**.
    
* You'll receive **more relevant opportunities**, which can mean **higher-paying surveys** and **fewer disqualifications**.

Providing your correct ZIP code helps ensure a smoother, more rewarding survey experience.
