# Customer Details
Collection and Delivery services use the **Customer Database** for **faster customer lookup**.
## Existing Customers
When entering the **phone number**, it provides you **suggestions** based on customer information currently in the database. The more you type, the narrower the search results are.
For Delivery orders, as you enter the phone number, it also shows you address suggestions that are associated with the customers. Clicking on the address **automatically fills in the fields**.
If an existing customer wants to use a **new address**, you can select the **customer's name and phone number**, then **add the new address** in the address tab.
## New Customers
If information is not in the customer database yet, you can **enter the details manually**. You can click between the **Phone**, **Name**, and **Address** tabs at the top.
After entering the customer details, click on **Save** on the upper right-hand corner.
