I’ve been on a bit of a shopping spree on Amazon Spain lately, and the packages have been piling up. After returning an item the other day, I took a closer look at the return label I had to print out and realized there’s a surprising amount of information packed into Amazon’s package labels! Today, let’s dive into this everyday item that we see but don’t always fully understand, especially how to find the information that’s crucial for returns and exchanges.

Every Amazon package you receive, whether it’s from Amazon directly or a third-party seller, comes with a shipping label. Besides the familiar name and address, this label contains a lot of codes. For instance, that long string of letters and numbers beneath the barcode is usually the package’s tracking number. But what’s more interesting are the internal codes that determine the package’s fate.
Understanding the Label Information
After taking a closer look, I found a few key pieces of information worth paying attention to:
- RMA: This code is essentially the ‘ID card’ for your return. When you request a return on Amazon, the system generates an RMA (Return Merchandise Authorization) number. This number appears on your return label, and it’s what warehouse staff use to identify who the returned package belongs to and which order it corresponds with. So, when printing your [Amazon return label], make sure this code is clearly visible!
- LPN: No, this isn’t a license plate number! In Amazon’s warehouse system, each item has an LPN (License Plate Number) code, used to track its movement within the warehouse. When you return an item, this code helps the warehouse quickly identify what you’ve sent back and process it into their inventory.
- Routing Code / Sort Code: The label often includes codes for sorting, like Posti 710 or SEUR 830. These are for the logistics system, telling machines which regional sorting center the package should go to. As a regular user, you can mostly ignore these, but it’s interesting to know they exist—it’s like deciphering the logistics system’s ‘Morse code’.
Key Points for Return Labels
When it comes to returns, many of us have been there. On Amazon Spain, there are generally two types of ‘labels’ for returns: one that you need to print and attach yourself, and another where you simply show a QR code to the courier for them to scan. If you need to print the label, pay close attention! Here’s a small table I’ve put together comparing the label characteristics for different return methods:
| Return Method | Label Handling | Important Notes |
| Drop-off at a Correos point | Print the label and attach it to the package | Ensure the RMA barcode is clear and securely attached |
| Drop-off at a Celeritas point | In most cases, show the QR code on your phone | No printing needed, but save the code from your email/app |
| SEUR home pickup | The driver brings a label or scans a QR code | Confirm with the driver beforehand to avoid issues with pickup |
Amazon’s package labels might seem complex, but the codes most relevant to us as consumers are RMA and LPN, which relate to return authorization and item identification. Understanding these will give you more confidence when handling returns and exchanges. I once had a return delayed for nearly a week because the ink on my self-printed label was too faint. So, here’s a tip for your next Amazon return label, learned through a painful lesson: always use a good printer and paper when printing labels!
