Creating shipping labels: A guide for online retailers
A shipping label is the digital or printed label that carries all relevant shipping information for a package and enables automated transport from sender to recipient. Terms such as Parcel label, parcel stamp Shipping label and shipping label refer to the same document. Anyone wanting to create a shipping label needs correct address data, accurate package dimensions, and the right print settings. Errors in any of these areas cause delays, additional charges, and, in the worst case, returns. This guide shows entrepreneurs and online retailers how the process works in 2026 and where the most common errors occur.
What data is required for a shipping label?
The correct entry of shipping data is the basis of every error-free shipment. Inaccurate information This leads to delays, additional costs, and returns. This applies to individual shipments as well as to large-scale shippers with hundreds of packages daily.
The following data is mandatory for every shipping label:
- Absentee address: Full name, street, house number, postal code, city, country
- Recipient address: The same fields, plus the correct country code for international shipments.
- Package weight: in kilograms, rounded to the nearest carrier-approved unit
- Package dimensions: Length, width, height in centimeters
- Shipping product: Standard parcel, express delivery, bulky goods or other categories
- Additional services: Insurance, preferred delivery date, age verification
Pro tip: Always weigh packages including packaging material. Carriers charge extra fees for discrepancies between the declared and actual weight, which can quickly eat up any shipping profit.
The technical requirements are minimal. An internet connection and a device are all that's needed for data entry. A standard inkjet or laser printer is sufficient for printing. Those without a printer can use the QR code option and print the label directly at a partner station.
| Shipping volume | Recommended method | Technical requirement |
|---|---|---|
| 1–5 packages per week | Web portal, manual | Browser, default printer |
| 6–50 packages per day | Web portal with batch function | Label printer recommended |
| 50+ packages per day | API integration | Own IT infrastructure, label printer |
| No printer available | QR code at partner station | smartphone |
Payment methods for online postage include credit card, PayPal, SEPA direct debit, and digital wallets such as Apple Pay or Google Pay. Most portals save payment details for subsequent orders, which speeds up the process for regular shipments.
How does creating a shipping label work, step by step?
The standard workflow for 2026 is fully digital: data entry via web portal or API, selection of the shipping product, payment, and subsequent output as a PDF or QR code. No step requires any special hardware.
Step-by-step process:
- Access the portal or establish an API connection: Open the carrier's web portal or shipping software that combines multiple carriers.
- Enter sender and recipient details: Please fill in all required fields. For international shipments, please add the country code and any customs information.
- Specify package details: Enter the weight and dimensions. The system will then calculate the price and check whether the package fits into the selected product category.
- Select shipping product and additional services: Choose standard shipping, express shipping, insurance, or delivery on a preferred date.
- Pay: Confirm payment method. The amount will be debited immediately or charged to the business account.
- Download label or save QR code: PDF for home printing or QR code for submission at a partner station.
- Print and stick on the label: Apply to the largest package surface, without creases or overlaps.
QR code-based labels They allow you to frank packages without a home printer. The package is dropped off at a branch or parcel locker, where the label is printed and affixed directly. This is convenient for occasional shippers. However, this method is inefficient for retailers with high shipping volumes.
| Printing method | Suitable for | Costs | Peculiarity |
|---|---|---|---|
| Home printers (inkjet/laser) | Individual shippers, small retailers | Low | Plain paper, protect in a foil pouch |
| Label printer (e.g. Zebra, DYMO) | Retailers from 20 packages/day | Medium | Self-adhesive paper, no cutting required |
| QR code at partner station | Occasional mailer without a printer | No hardware costs | On-site printing, no home printer required |
| On-site printing in branch | Individual shipments | Service fee may apply. | No separate device required |
Pro tip: Merchants who ship more than 20 packages daily should invest in a direct thermal printer. This type of printer prints directly onto thermal paper without ink, reducing operating costs and increasing throughput.
For Batch label creation Merchants upload a CSV file containing all shipment data. The system then generates a single PDF with all labels, which is printed and affixed to the packages. This method saves considerable time compared to manual data entry when processing 100 packages daily.
What errors occur when printing and attaching shipping labels?
Errors in label printing are one of the most common causes of scanning errors in the parcel network. Labels must be on the largest side of the package. They must be applied without folding or overlapping the barcode. Incorrect placement will result in manual rework and additional charges.
An overview of the most common sources of error:
- Incorrect print scaling: Many printers automatically scale PDFs to "fit to page." This distorts the barcode, making it unreadable by machines. Always set the scaling to 100%.
- Labels on edges or seams: A label that runs over an edge or sits on a seam cannot be scanned flat. Always place it on the largest flat surface.
- Transparent tape over the barcode: Light reflections from adhesive tape impair readability. Use self-adhesive label paper or matte document pouches.
- Fading expression: Insufficient ink or an empty toner cartridge will make barcodes unreadable. Print a test page before printing.
- Multiple labels on one package: Remove old labels from pre-packaged items or cover them completely so that scanners do not detect the wrong label.
Important: The shipping label is the digital and physical identification document of a package. Errors in weight, dimensions, or address information cause direct financial losses and delays. A single scanning error can delay a shipment by several days and trigger return costs that exceed the value of the goods.
Those without their own printer can use the QR code method. The package is dropped off at a branch, the label is printed there and affixed directly. This method is reliable because the printing takes place under controlled conditions. Shipping documents International shipping is subject to additional requirements, such as customs documents that must be correctly attached to the package.
Pro tip: Do not laminate labels. Glossy surfaces reflect light and can interfere with barcode scanners just like transparent tape.
How can the creation of shipping labels be automated?
API integrations completely eliminate manual data maintenance and allow batch generation of 50 to 500 or more labels daily. This is the crucial step for online retailers who want to grow without proportionally increasing their staff.
The core of the automation lies in the direct data transfer. An e-commerce system, such as a shop system, automatically transfers order data to the shipping platform. This platform generates the label, sends back the tracking number, and updates the order status. No manual copying, no typos.
Advantages of a central shipping platform with API connectivity:
- Media breaks are eliminated: Data flows directly from the shop to the shipping software, without any manual intermediate steps.
- Multiple carriers in one portal: Merchants choose the cheapest or fastest carrier depending on the destination country and package size, without having to switch between portals.
- Automatic customs forms: For international shipments, the system automatically generates customs documents based on the product data.
- Tracking numbers automatically transmitted: Customers receive their tracking number without manual intervention from the retailer.
| Other specifications | Manual process | Automated process |
|---|---|---|
| Data entry | Manually per package | Automatically from the ordering system |
| Label generation | Individually in the portal | Batch, hundreds of labels at once |
| Customs documents | Create separately | Automatically generated |
| tracking number | Copy manually | Automatically sent to customers |
| Error rate | High in volume | Low through system integration |
For the international shipping Automation is not a convenience, but a necessity. Customs regulations vary depending on the destination country, product category, and value of the goods. A system that understands these rules and automatically generates the necessary documents prevents customs delays and returns from abroad. Paket-international connects e-commerce systems directly with parcel services and customs services, enabling the creation of shipping labels and customs documents in a single step.
