To set up shipping carriers in SPL, open the shipping carrier settings, pick the carrier you fulfill with in Shopify from the Select Shopify Carrier dropdown, then choose the matching carrier in the Select TikTok Shipping Provider dropdown, and click Save. If your carrier is not listed, click + Add, choose Add Custom (Other), type your Shopify carrier name, and match it to the same TikTok provider. This mapping is what lets SPL sync tracking to TikTok Shop.
Carrier setup is small but load-bearing. Get it right once and tracking numbers flow to TikTok Shop automatically on every order. Get it wrong, or skip it, and tracking silently fails to sync, which puts your fulfillment metrics at risk.
This guide covers the standard mapping, the custom carrier route for anything not in the list, and why exact matching matters so much.
TikTok Shop Integration — SPL
Maps your Shopify shipping carriers to TikTok's provider names, including custom carriers, so tracking numbers sync cleanly to TikTok Shop on every fulfilled order. Set it once and forget it.

Why carrier mapping matters
When you fulfill an order in Shopify, you attach a shipping carrier to it. For TikTok Shop to accept the tracking, it needs that carrier expressed as one of its own approved providers. Carrier mapping is the translation layer: it tells SPL that your Shopify carrier equals a specific TikTok provider.
Without the mapping, SPL does not know which TikTok provider to report, so the tracking number fails to sync. The order can then look unfulfilled on TikTok Shop even though it has shipped, which affects your late-shipment and fulfillment metrics. One small setup step protects all of that.
Open the shipping carrier settings
In the SPL app, open your Order Settings and find the Shipping Carrier section. This is where you pair each Shopify carrier with its TikTok equivalent.
Map a Shopify carrier to a TikTok provider
Select your Shopify carrier
Click the Select Shopify Carrier dropdown and choose the carrier you use for order fulfillment in Shopify.
Select the matching TikTok provider
Click the Select TikTok Shipping Provider dropdown and choose the carrier that corresponds to your Shopify one.
Match the two as closely as the lists allow. The TikTok provider you pick should be the real-world carrier that actually moves the parcel, so the tracking link works for the buyer.
Add a custom carrier (if yours is not listed)
If your Shopify shipping carrier is not in the dropdown, you can add it manually.
- Click the + Add button below the existing mappings.
- In the Shopify Shipping Carrier dropdown, select Add Custom (Other), which sits at the end of the list.
- In the Shopify Carrier Name field, type the name of your Shopify shipping carrier exactly as it appears on your orders.
- Click the TikTok Shipping Provider dropdown and select the same carrier name from the list.
Save your configuration
Click the Save button to apply your changes. From now on, when you fulfill an order in Shopify with a mapped carrier, SPL reports the matching TikTok provider and the tracking number syncs across automatically.
Revisit this screen whenever you start using a new carrier, or if you notice tracking failing to sync for a particular one, since an unmapped carrier is the usual cause.
Tracking not reaching TikTok Shop? An unmapped carrier is the usual reason. SPL lets you map every Shopify carrier, custom ones included, to its TikTok provider so tracking always syncs. Free to install, plans from $9.99/month.

Shipping carrier setup FAQs
My tracking is not syncing to TikTok Shop. Is it the carrier setup?
Very often, yes. If a Shopify carrier is not mapped to a TikTok shipping provider, SPL does not know which provider to report and the tracking number fails to sync. Open the Shipping Carrier settings, check that the carrier on the affected orders is mapped to a matching TikTok provider, add it with + Add if it is missing, and click Save. That resolves most tracking sync problems tied to carriers.
What if my shipping carrier is not in the dropdown?
Use the custom option. Click + Add, choose Add Custom (Other) at the end of the Shopify Shipping Carrier dropdown, type your carrier's name in the Shopify Carrier Name field, then pick the same carrier from the TikTok Shipping Provider dropdown. Save, and your custom carrier is mapped like any other.
Do I have to match the carriers exactly?
You should match your Shopify carrier to the TikTok provider that genuinely carries the parcel. TikTok accepts tracking against its own list of providers, so choosing the corresponding one is what makes the tracking link valid for the buyer and keeps the order recognised as shipped. A rough or wrong match is a common reason tracking does not sync.
Can I map more than one carrier?
Yes. Add a mapping for every carrier you fulfill with, using + Add for each one. If you ship with several couriers, mapping them all means tracking syncs correctly no matter which carrier a given order goes out with.
Where does this fit with dropshipping suppliers?
If a dropshipping supplier fulfills your orders, the carrier they use still needs to be mapped here so their tracking syncs to TikTok Shop. Confirm which carrier your supplier ships with, then map it. Our dropshipping fulfillment guide covers this in the wider context of supplier apps and SLAs.
Do I need to set this up again for each order?
No. Carrier mapping is a one-time setup per carrier. Once a carrier is mapped and saved, every future order fulfilled with it syncs its tracking automatically. You only return to this screen to add a new carrier or fix a mapping.
