Frequently Asked Questions
Got a Question?
Q: What is 2D Transit?
A: 2D Transit is a state-of-the-art Fulfillment By Amazon (FBA) label processing software. It will allow you to create Amazon FBA labels, 2D labels, and FNSKU labels all in one place. 2D Transit allows the user to scan products and automatically print accurate labels for shipping to FBA. Amazon 2D labels get your products checked into FBA faster so you can keep products in stock and make more sales.
Q: What is a 2D label?
A: A 2D label is a QR Code that, when scanned, shows the carton contents of a box. To increase Fulfillment Center efficiency, Amazon has asked FBA sellers to provide carton contents for easier
and faster check-in of inventory and to avoid manual processing fees. Carton contents can be uploaded to Seller Central or encoded in a scannable 2D barcode label on the box.
Q: Does Amazon require 2D Labels?
A: Packages sent to an Amazon fulfillment center without a list of carton contents are subject to a 15-cents-per-unit manual processing fee during the months from January to October or a
30-cents-per-unit manual processing fee during the Christmas season from November to December. Scannable 2D labels list carton contents to expedite receiving and avoid the fees.
Q: Is it better to use a 2D label than to upload my carton contents to Seller Central?
A: Uploading your carton contents to Seller Central will get you around the fees, but it’s prone to mistakes. Inaccuracies in uploaded carton contents may lead Amazon to deny your shipment or
even suspend your account. With 2D Transit, our SafetyNet automatic shipment validation prevents your warehouse team from shipping a package to Amazon with the wrong items in the box. Ship to FBA with complete accuracy and remove a source of stress.
Q: Can I upload an Excel spreadsheet to create the 2D Labels?
A: Yes; 2D Transit accepts .xlsx, .csv, and .tsv files created from our templates. Use file import for quick upload of multiple shipment plans or multi-box shipments
Q: Is there a way to allow another user to do printing only?
A: If your goal is to have someone just do the printing, you still need to install printnode on that user’s PC in order for 2D to detect the printer, you only have to set the permission settings via 2D Transit for this user to be restricted with some features. Do note that printnode is a separate client app that is outside our capabilities for feature updates and permissions as we only manage permissions via 2D Transit.
Creating Shipping Plan
Q: When trying to work through the Seller Central Shipping Plan I got hit with errors such as “prepInstruction error”
A: In some instances, the prepInstruction we add to the template might not be the accepted prepInstruction by Amazon. You may update your template depending on what is being suggested by Amazon in the error response. As for the error saying “prepInstruction not available”, this is because sometimes Amazon cannot determine prepInstruction for certain ASINs at the moment and can be determined later on and this is solely on Amazon’s end. In some cases we leave it blank in order to proceed if NoPrep does not work.
Q: Shipment ID expire after clicking Approve, why?
A: This error is because the shipment ID has expired. This is designed by Amazon that if the shipping plan is created more than 48hours, the shipment ID will expire if there is no shipment created or approved. With this, please try to create another shipping plan and approve them once again.
Take note that you have an option to download the list of the shipping plan you have now before you delete it so that you will know which SKUs to import again. You can safely delete those shipping plans that you were not able to Approve. Thanks!
Q: I did not approve ALL shipments in the shipment plan before importing the SKU list via Seller Central FBA. Is this required?
A: Each shipment ID has 1 SKU List in Seller Central so it is fine not to approve all in 2D. You can only download SKU List in Seller Central if you already approved the shipping plan in 2D. So no it is not required.
Q: I renamed the Shipment, which changed the PO. Will renaming the shipments cause issues in finding the shipment plan?
A: Renaming the Shipment name should not be an issue since we base it on shipping ID when scanning the items.
Scanning and Labelling
Q: Is there a way we can process the PO pack slip from our orders, instead of working off an FBA number?
A: We can already get the shipment ID as soon as you are already done clicking the ‘Approve’ button using our shipping plan creation API workflow (Help -> Creating/Importing Shipment Plans -> Creating Shipping Plan). This will already show up in the Shipping Queue in Amazon seller central. You will still need to download the SKU list from Seller Central as you did in the old workflow, but you can import it into 2D Transit to process your shipment (also found in the guide above) in order for you to work with the shipment. By work with the shipment, I mean scanning, generating, and printing labels if you want. You can also print the shipping label on the Shipping Label page. And in order for you to have access to carrier services, you need to register for Easypost. For a more detailed guide about generating shipping labels, please check our help section: Help -> Generate Shipping Labels
Q: What is an FNSKU label?
A: An FNSKU barcode label is an optional alternative SKU label that ensures that the Amazon warehouse doesn’t commingle your inventory with other sellers’ inventory of the same goods.
With commingled inventory, customers who order from you may get some other seller’s product rather than the one you actually sent to FBA. If the other seller’s product is damaged or counterfeit, your brand could take the blame and the reputational damage in the form of one-star reviews. An FNSKU is a unique identifier for your products that prevents this. Amazon will apply these labels for you at the Amazon Fulfillment Center for 30 cents per unit, or you can save the money with 2D
Transit by applying the labels yourself.
Q: What if I scan the wrong product into a box? How do I ensure my shipment is accurate?
A: With SafetyNet, you will receive a notification when you scan a product that is not meant for the current box. This feature ensures that shipments are accurate, which will prevent loss and delay at the Amazon Fulfillment Center.
Box Pop Up
Q: Is there a way to turn off the reminder that pops up after you hit print for the box being completed?
A: No, and we don’t encourage disabling it if we can. The idea is that this is almost an e-signature situation where the user is verifying/agreeing that they are following all the guidelines.
Q: Amazon includes FBA labels on their printouts, do I need to label over their FBA label? Or can I include their fba label and the 2D Transit label?
A: If you are only using 2D Transit for the 2D barcode label, then yes you would use both labels: Amazon’s generated FBA ID and the 2D Transit 2D barcode label. But do note that we recommend you use our Combined 2D Label. A combined 2D label is the combination of FBA label and 2D carton contents label. In order to save the FBA manual processing fee that Amazon charges, we use 2D transit to generate 2D barcode labels. Originally you are adding a third label to your outbound boxes (shipping + FBA + 2D contents). But using the combined 2D label, the user is eliminating the need for the separate FBA label generated in Seller Central, saving time, eliminating the risk of putting a label on the wrong carton, and the supply cost of another thermal label.
Q: Hello, I’m having a problem printing my label. No labels are printed.
A: If your Default 2D Printer is ‘Browser’ it should display the print preview when you click Print in the screenshot you provided.
In this instance, you need to check your settings for Default Printer. But if you already enabled printnode via Printnode Printers settings, and you set printnode as the default printer instead of Browser, please check if the label is printed successfully using the printer you selected. If you did not set your Printnode up yet, please check the guide here: https://www.2dtransit.com/pages/tutorials/#printnode-guide.
As an additional reference, our clients have been using these printer models: For 2D labels, you may use Zebra GxT or Zebra 450; for FNSKU labels you may use Dyno printer. Technically you would base the sizes of the printers and do some test prints if needed. You can click Print Sample in Default Printer settings to do test prints and adjust sizes if needed. You may also check the guide for setting the default printer here for more info: https://www.2dtransit.com/pages/tutorials/#select-default-printer
If you already followed the 2D Transit guides and still have issues then our last troubleshooting is to check if you properly set up your printnode account via printnode site and printnode app. There is a log for the print command being sent from 2D to printnode in which we can check if the print command was successfully received. One of the common issues we receive is that a wrong printer may be selected on your setup which results in the label not printing.
Q: What type of printer works with 2D Transit?
A: 2D Transit requires a thermal printer. We recommend Zebra printers for 2D labels and Dymo printers for FNSKU labels.
Q: Can I save a partial shipment for later?
A: Yes. You can save a shipment as a draft, see progress to completion, and continue working on it at a future time.
Q: Can I track shipments through 2D Transit?
A: Yes, 2D Transit offers a summary dashboard showing all shipments and your warehouse’s prog- ress toward completion. Once a shipment has been sent, a link from the shipment plans page will take you directly to the Seller Central details page, where transit and receiving progress can be tracked.
Q: Can I prevent partner brands from seeing each other’s shipments?
A: Yes. 2D Transit offers access control at multiple levels. The account is owned at the level of your organization. Within that account, you can have multiple workspaces, corresponding to different warehouses or partner vendors. How many workspaces you can have is determined by the subscription plan you select. While there’s nothing preventing your partners and warehouses from sharing a single workspace, you may find it advantageous to use separate workspaces to avoid confusion and to protect your partners’ proprietary information. You can also control access at the level of the individual user. Each of your employees and each of your partners’ employees will have their own user account, with no upper limit to the number of users allowed. Users will only be able to see workspaces they’ve been invited to. Optionally, you can also limit users’ permissions within a workspace to prevent them from seeing other user’s work.
Q: How many logins can I have?
A: There is no upper limit to the number of users allowed. However, the maximum number of separate vendor-level workspaces you can have is determined by your subscription plan
Q: Is there a monthly contract or sign-up fee?
A: There is no sign-up fee and no penalty to cancel at any time. Try 2D Transit free for 7 days, and then pay month-to-month!
