Transparency Codes for Seller Fulfilled Prime Orders

By Todd Welch, founder of T-Code Manager. Published October 13, 2026.

Seller Fulfilled Prime orders are still orders you ship yourself. For a Transparency-enrolled product, that means the self-fulfilled rules apply: every unit needs its own valid code, and you give Amazon the codes when you confirm the order.

What changes with Prime is the clock. You're promising fast delivery and Amazon is measuring how often you keep that promise. A missing code that would cost an FBM seller an afternoon can cost an SFP seller a late shipment.

What Amazon says

Amazon's Seller Fulfilled Prime page doesn't list separate Transparency rules, so the standard self-fulfilled process is what applies. If you're unsure about a specific product, ask Transparency support.

For self-fulfilled Transparency products, Amazon's Transparency page says:

Contact Transparency support to start the operational performance review.
Provide your Transparency codes at order confirmation in Seller Central so Amazon can monitor your units.
Protection isn't active until the product passes the review.

On the SFP side, as of October 2026, Amazon's page says you run a 30-day trial and meet the performance requirements before you're enrolled. After that, Amazon reviews performance weekly, and ongoing failures can lead to your Prime offers being disabled. Prequalification looks at late shipment, valid tracking and cancellation rates.

Put those together and the risk is clear. If your code process slows a Prime order down, it shows up in the same metrics that keep you in the program.

Where codes slow down SFP orders

Running out of codes. You can't ship an enrolled unit without one, and a Prime order won't wait for the brand or for Amazon to send more.
Hunting for codes. A packer digging through a CSV file for an unused code is a packer who isn't packing.
Duplicates. Two packers grabbing codes from the same file can put one code on two units.
Confirmation bottlenecks. Every unit needs a code when you confirm, so one missing code holds up the whole order.
Bulk label buying. If you buy shipping labels in bulk, check how codes get entered for those orders before you rely on it. If they go in afterward, for example with a shipping confirmation file, that's another step to remember.

Before you put Transparency products on SFP

Pass the self-fulfilled review first. Get your Transparency process working on regular FBM orders before you take on Prime delivery promises.
Run your SFP trial with real code volume. The 30-day trial is the time to find out whether your code process keeps up on your busiest days.
Mark enrolled SKUs everywhere. In your shipping software, on pick lists and on the shelf. Packers should know before they pick that an order needs codes.
Set a code reorder point for each enrolled product. Base it on your busiest day, not your average one.

Two ways to run the packing station

Option 1: label at pack-out

The packer prints one label per unit on the order, applies them and reports the codes from those labels at confirmation. The codes on the units and the codes you report come from the same print job, so they match as long as nobody mixes up labels between orders.

This is the simplest setup for most SFP sellers. The downside is a print step at the packing station, so the printer has to be fast and reliable.

Option 2: pre-labeled inventory

Units are labeled when they're received or prepped, so packing is just pick, pack and ship. Faster at the packing station.

The catch is that you still have to report the exact code that's on each unit you ship. That means scanning or recording the code on every unit at pack-out. Skip that step and you'll report codes that don't match what went in the box.

If your factory applies codes, you're already in Option 2. See applying codes at the factory.

Keep enough codes on hand

For SFP, think about codes the way you think about inventory with a hard promise attached.

Know how many units of each enrolled product you ship on your busiest day.
Know how long it takes to get more codes. Brands order from Amazon. Resellers wait on the brand.
Keep at least enough codes to cover that lead time on a busy stretch, plus a cushion for Q4 and promotions.

There's a simple formula and a worked example in ordering Transparency codes in bulk.

Entering codes at confirmation

You have the same options as any self-fulfilled order:

Seller Central: enter codes on the confirm shipment page.
Shipping software: tools that connect to Amazon, such as ShipStation, let you enter Transparency codes on enrolled order items.
Shipping confirmation file: upload codes in bulk. Test on a small batch first, especially for orders with several enrolled SKUs or large quantities, and confirm Amazon accepted the codes.

Whichever you use, paste codes instead of typing them. A typo in a code is an invalid code.

Keep a log

Record every code with its order ID and ship date. If Amazon, a customer or the brand asks about a unit later, you want the answer in seconds. It also helps with returns, because you can check whether a returned unit carries the code you shipped on that order.

For the full step-by-step on self-fulfilled orders, read the FBM labeling guide. And if a unit has already gone out without a code, read what happens when units ship without codes.

How T-Code Manager fits SFP

SFP orders go through the same FBM dispensing flow in T-Code Manager:

Scan the product. ASIN, UPC, SKU and FNSKU all work.
Enter the Amazon order ID and the quantity.
T-Code Manager hands you that many unused codes, marks them used right away and logs them with the order ID.
Copy one code at a time, or copy them all one per line or comma separated. There's an option to strip the "AZ:" prefix for pasting into ShipStation.

For units you label ahead of time, label printing works the same way: scan, enter a quantity, print. Dispensing hands out new, unused codes, so don't use it for units that already carry a label. For those, report the codes on the labels. The dashboard shows how many codes every product has left, low-stock emails warn you before an enrolled SKU runs dry, and on the Growth plan and up, forecasting estimates how many days of codes you have left.
