A shipping label is the printed sticker fixed to the outside of every parcel that tells the courier where to deliver the package, who to return it to, and how to identify the shipment in the carrier's system. A complete label includes the sender's return address, the recipient's delivery address, a tracking number (often as a barcode), the service type (Standard, Express, Priority), the parcel weight, and the order or reference number. Most ecommerce sellers print labels in the standard 4 x 6 inch (100 x 150 mm) thermal format using a Zebra, Munbyn, or Rollo printer, but plain A4 paper works fine for low-volume shipments.
These three documents travel with every shipment but serve different purposes. A shipping label goes on the outside of the box and tells the courier where to deliver it. A packing slip goes inside the box and lists the items so the customer can verify the contents. A commercial invoice is required for cross-border shipments and declares the value, origin, and HS code of goods for customs clearance. For freight shipments by sea or land, you also need a bill of lading. Domestic ecommerce orders typically need only a shipping label and a packing slip; international orders need all four documents.
A complete ecommerce shipping label should always include: sender name and return address (so couriers can return undeliverable packages), recipient name, full delivery address, and phone number (the most prominent block on the label), the tracking number as both human-readable text and a scannable barcode, the service level (Standard, Express, Priority — affects routing and SLA), the parcel weight in kilograms (used for billing and dimensional weight checks), the order or reference number for warehouse cross-checking, and any special handling flags such as Fragile, This Side Up, or Cash on Delivery. Marketplaces such as Shopee, Lazada, and TikTok Shop also require their marketplace order ID printed on the label so first-mile staff can route the parcel to the correct sortation lane.
The 4 x 6 inch (100 x 150 mm) format is the global ecommerce standard — it is what Shopee SPX, Ninja Van, J&T, DHL eCommerce, FedEx, and most marketplace label generators output by default. Other common sizes include 4 x 4 inch (used by USPS for some priority products), 6 x 4 inch landscape, and A4 (210 x 297 mm) sheets with 1, 2, 4, 6, or 10 labels per page. This generator outputs a 4 x 6 portrait label that prints cleanly on a thermal label printer or scales to fit a single A4 page in your browser's print dialog. Your data stays in your browser and is never sent to any server.
For volumes under 30 parcels per day, an A4 inkjet or laser printer with adhesive label sheets is the cheapest setup — expect to pay around S$0.05-0.10 per label in materials. Above that volume, a dedicated thermal label printer (Zebra ZD220, Munbyn ITPP941, Rollo, or the local SPX/Ninja Van branded units) is faster, uses no ink, and produces sharper barcodes — expect S$200-450 upfront and S$0.02-0.04 per label in thermal media. Always test the barcode with the carrier's scanning app before shipping a batch. Many marketplaces such as Shopee and Lazada provide their own pre-formatted labels in seller centre, so use this generator only for orders that come from your own website, manual orders, or marketplaces that do not auto-generate labels (such as some Temu semi-managed shipments and direct B2B orders).
Manually pasting addresses into a label template works for a handful of orders per day. Once you scale past 20-30 orders per day across multiple sales channels, the manual approach becomes the bottleneck — copy-paste errors, wrong tracking numbers, and labels printed for the wrong parcel start eating into margin. Multi-channel order management tools like OneCart pull orders from Shopify, Shopee, Lazada, Amazon, TikTok Shop, WooCommerce, and other platforms into a single dashboard, then auto-generate shipping labels and packing slips with the correct carrier, tracking number, and marketplace ID for every order. This eliminates the manual step entirely and means every parcel leaves your warehouse with the right label on the first try.
OneCart auto-generates shipping labels, packing slips, and tracking updates for every order — across Shopee, Lazada, TikTok Shop, Shopify, Amazon, and more.
