How to add Custom Random Order Number in Magento 2
- By default, Magento 2 generates order numbers sequentially, based on the time of the order. However, in some cases, you may want to use custom random order numbers instead. For example, you may want to use a different numbering system for your orders, or you may want to prevent customers from being able to predict the next order number. In this article, we will show you how to add a custom random order number in Magento 2.
- To add a custom order number in Magento 2, you can follow these steps.
Step 1 : Register your module
Create a custom module in Magento 2.
Step 2 : Create Configuration
- Create system.xml file at
app/code/Dolphin/CustomOrderNumber/etc/adminhtml/ folder
<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
<system>
<tab id="dolphin" sortOrder="200" translate="label">
<label>Dolphin</label>
</tab>
<section id="custom_order_number" showInDefault="1" showInStore="1" showInWebsite="1" sortOrder="210" translate="label">
<label>Custom Order Number</label>
<tab>dolphin</tab>
<resource>Dolphin_CustomOrderNumber::config</resource>
<group id="general" showInDefault="1" showInStore="1" showInWebsite="1" sortOrder="10" translate="label">
<label>General</label>
<field id="order" showInDefault="1" showInStore="1" showInWebsite="1" sortOrder="10" translate="label" type="text">
<label>Order Number</label>
<comment/>
</field>
<field id="invoice" showInDefault="1" showInStore="1" showInWebsite="1" sortOrder="10" translate="label" type="text">
<label>Invoice Number</label>
<comment/>
</field>
<field id="shipment" showInDefault="1" showInStore="1" showInWebsite="1" sortOrder="10" translate="label" type="text">
<label>Shipment Number</label>
<comment/>
</field>
<field id="creditmemo" showInDefault="1" showInStore="1" showInWebsite="1" sortOrder="10" translate="label" type="text">
<label>Credit Memo Number</label>

Leave blank for default increment number.<br/>
<b>Sample Format</b><br/>
ABC_{str3}{num3}{increment_id}<br/>
<br/>
<b>The Following variables can be used.</b><br/>
{increment_id} - Default increment id.<br/>
{str3} - Random string with 3 characters.<br/>
{num3} - Random number with 3 digits.<br/>
<b>If the number is greater than 9 then take 9 static.</b><br/>]]>
</comment>
</field>
</group>
</section>
</system>
</config>
Here is the screenshot of configuration.
Leave blank for Magento default increment number.
The Following variables can be used.
- {increment_id} – Default increment id.
- {strX} – Random string with X characters.
- {numX} – Random number with X digits.
- If the number is greater than 9 then it’ll consider 9 only.
Sample Format
- ABC_{str3}{num3}{increment_id}
Step 3 : Override the Sequence.php file
Create di.xml at app/code/Dolphin/CustomOrderNumber/etc folder
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Magento\SalesSequence\Model\Sequence" type="Dolphin\CustomOrderNumber\Model\Sequence" />
</config>
Step 4 : Create Sequence.php for apply custom number
Create a file Sequence.php at app/code/Dolphin/CustomOrderNumber/Model folder for extend class from Magento\SalesSequence\Model\Sequence.
<?php
namespace Dolphin\CustomOrderNumber\Model;
use Magento\Framework\App\ResourceConnection as AppResource;

The generateIncrementId() method generates a unique increment ID based on the specified pattern and type.
If the increment ID is not unique, it generates a new one and checks again until a unique increment ID is found.
Implementing a custom random order number can be a useful feature for your Magento 2 store to enhance the security and uniqueness of your order numbers. With the right steps and guidance, you can successfully implement this feature and provide a more personalized experience for your customers.
