FAQ: Adding Shipper Reference Numbers to Stamps.com Labels Using Shipstore


What is a Shipper Reference Number?

A shipper reference number is a custom identifier that you can add to your shipping labels to help track and organize your shipments. This could be:

  • Your internal order number
  • Customer reference number
  • Invoice number
  • Product SKU
  • Any other identifier relevant to your business

How to Add a Shipper Reference Number in Shipstore

Step 1: When creating a shipment in Shipstore, locate the "Memo 1" field in the shipping form.

Step 2: Enter your desired reference number in the Memo 1 field. This information will be transmitted to Stamps.com as your shipper reference.

Step 3: Complete the rest of your shipping details and process the label as normal.

Step 4: The reference number will appear on your printed Stamps.com shipping label.

Frequently Asked Questions

Q: Where does the reference number appear on the Stamps.com label?

A: The shipper reference number entered in Memo 1 will typically appear in the reference section of your Stamps.com shipping label, usually near the tracking number or in a designated reference field.

Q: Is there a character limit for the reference number?

A: Yes, most carriers have character limits for reference numbers (typically 24-35 characters). Keep your reference numbers concise to ensure they display properly on the label.

Q: Can I use special characters in the reference number?

A: It's recommended to use only alphanumeric characters, hyphens, and underscores. Avoid special symbols that might cause processing issues.

Q: Will the reference number help with tracking?

A: While the reference number appears on the label and can help you identify packages, the primary tracking is still done through the carrier's tracking number. The reference number is mainly for your internal organization.

Q: What if I forget to add a reference number?

A: You'll need to create a new label if you want to include a reference number. Once a label is printed, you cannot modify the reference information.

Q: Can I use the same reference number for multiple shipments?

A: Yes, but using unique reference numbers for each shipment will make tracking and organization much easier.

Q: Does the reference number affect shipping costs?

A: No, adding a reference number does not impact shipping rates or fees.

Best Practices

  1. Use a consistent format for your reference numbers (e.g., ORD-12345, INV-2024-001)
  2. Keep them short but descriptive to ensure full visibility on the label
  3. Avoid spaces - use hyphens or underscores instead
  4. Test with a sample shipment to see how your reference numbers appear on the actual label
  5. Document your reference number system for team consistency
