What Is a Shopify Order ID and Shopify Order Number?
Shopify Order ID
This is a system-generated numeric identifier that Shopify uses internally. This ID plays a key role in backend operations, helping with API calls, system-level tracking, and integrations with third-party apps. It is not shown to customers and is mainly relevant for developers, support staff, and advanced users managing automation or troubleshooting technical issues.
Shopify Order Number
This is the visible, sequential number assigned to each new order, starting at #1001 by default. This is what customers see in their emails and what they use when asking, “Where’s my order?” You can customize it with prefixes or suffixes (e.g. INV-1001), but you can’t reset or skip numbers. It makes order tracking more user-friendly for both store owners and buyers.
Shopify Order ID vs. Order Number: Key Differences
Feature | Shopify Order ID | Shopify Order ID |
|---|---|---|
Visibility | The Order ID is hidden from customers and only visible in the admin dashboard and APIs. | The Order Number is visible to both customers and store staff on receipts and emails. |
Purpose | It is used for internal order management, automation processes, and integrations. | It is used for external reference, support communication, and customer tracking. |
Format | The Order ID is a long, non-sequential number that cannot be changed or customized. | The Order Number is short, sequential (e.g. #1001), and allows prefixes or suffixes. |
Importance | It ensures system accuracy and is essential for backend reliability and third-party tools. | It improves customer experience by providing a simple, traceable reference point. |

When to Use Shopify Order ID vs. Order Number
Shopify Order ID
- API integrations & automation: If you’re connecting Shopify to third-party apps or automation tools, the Order ID is your best choice. It ensures accurate tracking, avoids duplicate entries, and keeps workflows running smoothly. The Shopify Order ID format is perfect for systems that rely on precision.
- Internal reporting & troubleshooting: When developers or Shopify support need to investigate an issue, they use the Order ID. It’s like a case file number specific, detailed, and unique to each order. If an order disappears or payments don't match, the Order ID is the most reliable way to track it down.
- Bulk data exports & ERP systems: Large businesses that use ERP software or run frequent data exports rely on Order IDs. Since the ID never changes and follows a consistent structure, it helps prevent mismatches when syncing order details.
Shopify Order Number
- Support tickets & customer inquiries: Customers don’t care about system identifiers. They just want to know where their order is. That’s why the order number matters, it’s easy to read, shows up on emails and receipts, and is what customers quote when reaching out for help.
- Invoices & branding: Order numbers can be customized to suit your brand. You can add prefixes or suffixes like “LUX-1001” for a luxury brand or “SOCKS-1001” for something more playful. This gives your invoices and receipts a consistent, branded look.
- Marketing & loyalty programs: Some stores use order numbers creatively in promotions. For example: “Show your last order number for 10% off your next purchase.” This approach works well because order numbers are short and easy for customers to find. You wouldn’t use the long Shopify order ID format for this it's too complex and meant for back-end use only.
Take Note: Shopify’s system is reliable, but things can get strange. During flash sales or when importing data, two different orders might accidentally get the same order number. Test orders can also show up in your data. In both cases, the order ID is the only way to tell them apart.

Three Ways Merchants Can Customize Shopify Order Numbers
Here’s how you can customize order numbers safely while ensuring Shopify’s internal tracking remains accurate.
1. Prefixes & Suffixes: The Easy Route
Shopify lets you add prefixes and suffixes to order numbers via Settings > General > Standards and Formats.
For example, a luxury store might use LUX-1001, while a sneaker shop could choose SNEAKS-1001. The sequence of the numbers remains unchanged, but the added text makes the order numbers more recognizable and aligned with your brand identity.
2. Third-Party Apps: The Advanced Route
If you want full control over your order numbers, including changing their sequence, you’ll need to use a third-party app. Apps like Cleverific Order Editor allow merchants to modify order formats, add custom markers, or create unique numbering systems.
This option is especially useful for businesses migrating from other platforms that want to keep their existing numbering style.

3. Custom Code: The Developer’s Route
For merchants with coding skills or access to a developer, Shopify’s API enables custom order number formatting. This method requires technical expertise but offers the most flexibility. It also helps streamline order management and reporting.
Businesses can create smart order codes that indicate things like:
- Warehouse location
- Shipping method

Best Practices for Managing Order Identifiers
Managing Shopify order ID and order number effectively can improve your internal processes and enhance customer support. Here are some best practices to keep things running smoothly.
- Standardized naming & formatting: Keep order numbers consistent by using prefixes or suffixes that make orders easy to recognize at a glance.
- Clear documentation & team training: Make sure everyone on your team understands the difference between order ID and order number. Creating a quick reference guide or FAQ helps prevent mistakes when responding to customers or dealing with technical issues.
- Automated tracking & reporting: Leverage Shopify’s built-in reports or third-party apps to track order IDs automatically. Automation cuts down human error and improves accuracy in financial reports, inventory management, and customer service.

Order ID vs. Order Number: What Merchants Often Ask
Can I reset the order number sequence in Shopify?
No, Shopify doesn’t let you reset the actual order number sequence. The numbering continues from where it started. You can still add prefixes or suffixes to help organize or separate order types.
What if I’m importing orders from another system with existing numbers?
Shopify lets you assign your old order numbers during the import process by setting them as the order "name." This keeps your order history consistent across platforms.
Can two orders have the same order number?
It’s rare, but duplicate order numbers can occur during data imports or with custom apps. In these cases, the order ID is the only guaranteed way to tell orders apart.
Should I store both order ID and order number in my records?
Yes. Keeping both helps you cross-reference internal systems and customer conversations more easily. It also improves troubleshooting, especially when using third-party integrations.
