# Types of QR codes & barcodes.

## Not all QR codes are the same—each type serves a different purpose and provides unique advantages. On Delivr, you can select the QR code type that best aligns with your campaign goals, tracking needs, and long-term plans. Understanding these differences will help you maximize our platform and your marketing efforts.

## The Two Main Types of QR Codes in Delivr.

### **1. Dynamic QR Codes** (Trackable & Editable)

- **Best for** marketing campaigns, product packaging, labels, DOOH, or any situation where you may need to update the destination or measure engagement.
- **Key Features**  
  - Change the destination URL at any time without reprinting the QR code.  
  - Track scans in real-time (location, time, device type, etc.).  
  - Add campaign names, notes, and tags to make organization easier.
- **Benefits**. Flexible, measurable, and future-proof.
- **Design.** Standard & Custom Design

### **2. Static QR Codes** (Fixed & Non-Editable)

- **Best for** permanent uses where the destination will never change.
- **Key Features**  
  - Directly encodes the destination into the QR code.  
  - No tracking or analytics available.  
  - Cannot be updated after creation.
- **Benefits**. Simple, cost-free, and doesn’t require an ongoing subscription.
- **Design.** Standard & Custom Design

## **Choosing the Right Type for Your Needs**

|     |     |
| --- | --- |
| **If You Need To…** | **Choose** |
| Track scans and engagement | Dynamic |
| Update the destination after printing | Dynamic |
| Use once with no changes or tracking | Static |
| Link to content that will never change | Static |
| Run time-sensitive marketing campaigns | Dynamic |

## **How to Select a QR Code Type in Delivr**

- When creating a **new campaign**, you’ll be prompted to choose between **Dynamic** and **Static**.  
- You can also edit an existing **Dynamic** campaign’s destination anytime from your dashboard—but Static codes cannot be changed once generated.

## **Pro Tip**

If in doubt, start with **Dynamic QR Codes**. Even if you don’t need analytics today, having the flexibility to update your destination later can save you time, money, and reprints.
