Free Shipping Label Generator — USPS, UPS, FedEx, DHL & Royal Mail

How to Create a Shipping Label

Enter the sender name, address, city, state, postcode and country in the From section. Furthermore, add a phone number if the carrier or customs authority requires one for delivery notifications.

Fill in the recipient details in the To section using the same fields. Furthermore, use Address Line 2 for apartment numbers, suite numbers, floor designations or building names that do not fit on the first line.

Select your shipping carrier from USPS, UPS, FedEx, DHL or Royal Mail. Furthermore, the carrier name appears as a header on the generated label. Choose Generic if you are using a local or regional carrier.

Pick a service level to indicate the speed of delivery. Furthermore, Standard, Express, Overnight, Economy and Freight options cover the full range of shipping speeds from next-day to multi-week transit.

Add handling instructions if your package requires special care. Furthermore, FRAGILE, PERISHABLE, DO NOT STACK, THIS SIDE UP, KEEP DRY and HANDLE WITH CARE are all available as bold label banners.

Enter the package weight with your preferred unit and the dimensions in centimetres or inches. Furthermore, these details help the carrier calculate volumetric weight and apply the correct shipping rate.

Click Generate Label to see a live preview inside the widget. Furthermore, the preview updates every time you change any field. Click Print Label to send the label directly to your printer using the browser print dialog.

Competitor Analysis: How This Tool Compares

We analysed the top five shipping label generators ranking on Google to identify feature gaps. Furthermore, this analysis informed the design of every feature in this tool.

Invoicer.ai is the current market leader with the most features. Furthermore, LazyTools matches every Invoicer.ai feature except barcode generation and industry presets. The key advantage of LazyTools is zero JavaScript dependencies, faster loading and fully offline capability.

What Information Does a Shipping Label Need?

A valid shipping label requires the sender full name and complete mailing address. Furthermore, the Universal Postal Union S42 standard mandates that the destination country appears on the last line of the address block in uppercase letters.

Carrier-specific requirements add tracking numbers, barcodes and service indicators. Furthermore, USPS requires a ZIP+4 code for automated processing, while Royal Mail uses postcodes formatted as two groups separated by a space.

Weight and dimensions determine shipping costs through actual weight or volumetric weight calculations. Furthermore, carriers charge whichever is higher. The volumetric formula is length times width times height divided by a dimensional factor, typically 5000 for metric or 139 for imperial.

Handling instructions communicate special requirements to warehouse and delivery staff. Furthermore, the International Safe Transit Association recommends standardised markings that this tool follows.

Label Sizes and Printer Compatibility

The 4x6 inch label is the global standard for thermal shipping printers. Furthermore, Dymo 4XL, Zebra ZP450, Brother QL-1100 and ROLLO printers all accept this format natively with no driver configuration.

A6 at 105 by 148 millimetres is the international standard used by Royal Mail, DPD, Hermes and PostNL in Europe. Furthermore, A6 labels can be printed on A4 sheets with two labels per page and cut along the midline.

Inkjet and laser printers work for occasional shipping. Furthermore, use matte sticker paper for adhesive labels or plain paper inserted into a clear shipping pouch attached to the package exterior.

Carrier-Specific Label Requirements

USPS Requirements

USPS labels must include ZIP+4 codes for automated sorting. Furthermore, the Intelligent Mail barcode encodes delivery point, service type and mailer ID. USPS Publication 28 at pe.usps.com governs all addressing standards.

UPS Requirements

UPS labels use the MaxiCode 2D barcode containing the tracking number and delivery address. Furthermore, UPS requires a service indicator showing Ground, Next Day Air or other service level selections.

FedEx Requirements

FedEx uses a PDF417 barcode on its labels encoding routing and tracking data. Furthermore, residential versus commercial delivery designation affects pricing and delivery expectations.

DHL Requirements

DHL Express labels include a waybill number and piece count for multi-box shipments. Furthermore, international DHL shipments require an electronic customs declaration linked to the waybill.

Royal Mail Requirements

Royal Mail uses the UK postcode as the primary sort key. Furthermore, machine-readable labels require the postcode in the penultimate line with the country on the final line for international items.

International Shipping Label Rules

International shipments require customs declarations listing the contents, value and country of origin. Furthermore, a CN22 customs form is required for packages under 2 kilograms and a CN23 for heavier items.

The destination country name must appear in English and optionally in the language of the destination country. Furthermore, the UPU recommends printing the country in uppercase bold letters on the final line of the address.

Harmonised System codes classify goods for customs purposes. Furthermore, incorrect HS codes cause delays, additional duties and potential seizure at the destination border.

Prohibited and restricted items vary by country. Furthermore, the UPU publishes a country-by-country guide to postal prohibitions at upu.int that every international shipper should consult.

Packaging Best Practices

Place the label on the largest flat surface of the package. Furthermore, avoid placing labels on seams, edges, tape lines or over box closures where they may peel or tear during transit.

Cover the label with clear packing tape to protect against moisture, abrasion and handling damage. Furthermore, ensure the tape does not obscure text, barcodes or any carrier-specific markings.

Remove or completely cover any old labels, barcodes or addresses from reused boxes. Furthermore, conflicting labels cause automated sorting errors, misrouting and delivery failures.

Use double-walled corrugated boxes for fragile items. Furthermore, the International Safe Transit Association testing protocols at ista.org define packaging standards for different product categories and shipping environments.

Creating Return Labels

Click the Swap button between the From and To sections to instantly reverse sender and recipient addresses. Furthermore, this creates a return label from the same shipment data without re-entering any information.

Print a return label and include it inside the outgoing package for customer convenience. Furthermore, pre-printed return labels significantly increase return compliance rates according to UPS research.

Some carriers offer pre-paid return labels where postage is charged only if the label is used. Furthermore, USPS Pay-on-Use Return Labels and UPS Returns Technology both offer this capability through their commercial shipping portals.
