FBA Label: Everything You Need to Know to Avoid Shipping Nightmares

2025-07-10

1.Why FBA Label Matter More Than You Think

Let’s start with the question on every Amazon seller’s mind: Do labels really matter that much? Short answer yes, they absolutely do. Whether you are a primary-time supplier or going for walks a six-parent Amazon shop, getting your FBA label setup wrong can absolutely derail your business.

When shipping to Amazon’s achievement centers, you are not simply placing a decal on a container. You're sending a signal to their system about what’s inner, in which it must move, and who it's from. One small misprint can cause your inventory to be delayed, misdirected, or even rejected. Imagine spending hundreds on shipping just for your items to be sent back. That’s why using the correct Amazon FBA labels is non-negotiable.

The thing is, many sellers overlook the FBA label template requirements. They either resize, reposition, or reprint incorrectly. Or worse use a random sticker sheet they picked up from a local store without checking compatibility. This is how small labeling errors snowball into massive fulfillment nightmares.

Another hidden pain point? Not using proper FBA label service options. Some sellers think it’s cheaper to print labels themselves. That’s fine if you’re using the right printer, right template, and right materials. But if not, it might be worth outsourcing. Amazon offers a FBA labels service where they print and apply your labels for a per-item fee. Think of it as paying for peace of mind.

So yes, labels might seem like a small part of the process, but they’re a massive deal in the eyes of Amazon. If your labels don’t scan correctly or aren’t readable by their systems, your product won’t move and that means you don’t earn.
