Why can’t I create a shipping label?

Some carriers validate address fields very strictly. If the house number is missing or placed incorrectly, the label may fail.

If the combination is invalid, the carrier may reject the shipment data.

If the sender details are incomplete, or if one of the fields exceeds the carrier's character limit, the label may not be created.

Some shipping methods only work when the shipment weight and dimensions are filled in correctly.

Some carriers reject special characters or Non-Latin Scripts in the name or address fields.

If the error message does not specify which field is causing the issue, use the browser Developer Tool to find the exact cause. Open the Network tab, reproduce the error, and check the response of the failed request. It will usually contain the specific field name or validation error. See step 8 for instructions on how to do this.

Once a label is created, the commercial invoice cannot be changed in Sendcloud. If you made a mistake in the item description or declared value, cancel the label and recreate it with the correct details before the shipment is handed to the carrier.

The HS code must be filled in and in the correct format. A code that is too short, too long, or incorrectly formatted will cause label creation to fail. Use the Sendcloud HS Code Finder if you are unsure which code applies to your product.

Every product in the shipment must have a value greater than 0.00. If any item value is missing or set to zero, some carriers will reject the shipment.

For certain destinations, customs or tax numbers are required at the sender level. If they are missing or saved in the wrong place, the label will fail even if the rest of the shipment details are correct.

This usually means the numbers are entered in the shipment form but not saved in your sender address settings. Go to Account Settings Address Business details and save them there. The error should resolve on the next attempt.

For shipments to Switzerland, the total order value is required before you can proceed. Make sure all product details including value and weight are filled in under the customs information section.

Shipments from the EU to the UK are international shipments that require customs clearance, even if you have a shipping rule pointing to a domestic method. Make sure you have a method that supports the UK route and that your GB VAT and EORI numbers are saved in your sender address. See step 4 for customs requirements.

The Canary Islands are treated as a separate destination in Sendcloud with country code IC, not as part of Spain. Not all carriers that ship to Spain will also ship to the Canary Islands. Check availability in Shipping Prices using IC as the destination.

Some shipping methods to the USA are temporarily suspended due to import regulations. Availability changes, so always check the current status in Shipping Prices before creating the label. For the latest updates on carrier suspensions, check our carrier disruptions page.

Monaco uses postal code 98000, which some carriers do not accept. If you encounter a postal code validation error for Monaco, check whether the carrier or shipping method supports the destination. Not all methods available for France will work for Monaco.

This is a generic error returned by the carrier with no specific cause. Wait a few minutes and try again. If it keeps appearing, check the status page for ongoing incidents. If there are none, contact Support and include the shipment ID and a screenshot of the error.

The carrier's system is temporarily unavailable. This is not caused by your shipment details. Wait a few minutes and try again. If it persists, check the status page. If no incident is reported, contact Support.

This error appears during label generation and usually means a temporary issue on the carrier's side or in the Sendcloud system. Check the status page for ongoing incidents and try again after a few minutes. If the error persists, contact Support with the shipment ID.

This error appears when the carrier rejects the label announcement. It can affect both outbound and return labels. Common causes are a temporary carrier issue, a shipping method not supported for that route, or a contract setting that is not configured correctly. Try again after a few minutes. If the error persists for more than a day, contact Support with the shipment ID and the carrier name.

The carrier could not validate the delivery address. This is a carrier-side rejection, not a Sendcloud validation error. Check the street name, house number, postal code, and city carefully. Some carriers also reject addresses that contain special characters or have a postal code that does not match the city. Correct the address and try again.

The carrier rejected the address even though it appears correct. This can happen when the carrier's database does not recognise the street name format. Try adjusting the street name slightly, for example by removing punctuation or abbreviations, and create the label again. If the address is correct and the error persists, contact Support.

The postal code format is not accepted for the selected carrier or destination. Some carriers require specific formats — for example, Latvian postcodes must be entered without the LV- prefix. Check the required format for the destination country and correct the postal code before trying again.

The carrier returned no valid shipping method for the shipment details you entered. This is usually caused by the origin, destination, weight, or parcel dimensions falling outside the carrier's accepted range for that method. Check the available methods in Shipping Shipping Prices and select one that matches your shipment.

The service point selected for this shipment is no longer available. Go back to the shipment and select a different service point. If no service points appear, check that the service point delivery method is still active under Shipping Carriers.

The carrier rejected the contract credentials. Go to Shipping Carriers and check that the credentials for this carrier match exactly what the carrier provided. If you recently changed your password or contract details with the carrier, update them in Sendcloud as well. If the credentials are correct and the error persists, contact Support.

This error appears when using the Sendcloud API without a payment method set up on the account. Go to Account Billing Payment methods and make sure a valid direct debit or card is linked before creating labels via the API.

The carrier's API is receiving too many requests in a short time. Wait a few minutes before trying again. If you are creating labels in bulk, try creating them in smaller batches.

The carrier has already registered a shipment with this reference. This can happen if a label was created but not cancelled correctly before a new attempt. Cancel the existing label first and then try again.

The selected shipping method is not available between the origin and destination. This often appears for GLS shipments when the route is not supported. Check the available methods in Shipping Shipping Prices and select a supported method for that route.

This error appears when a DPD shipping method has lost its connection to the DPD Cloud Service. It cannot be fixed through the panel. Contact Support as this requires manual intervention at the account level.

This error appears when creating a label with a direct Poste Italiane contract and the shipment includes a service that is not covered under that contract, such as a return method. Check that the shipping method you selected is included in your Poste contract. If you are unsure, contact Support with the error details.

SwissPost requires a home post office (Heimatpostamt) to be specified in the recipient address for certain shipments. This field is not standard in Sendcloud. Contact Support as this requires specific configuration for your SwissPost contract.

Shipments to Andorra require the recipient's identity document type and number (DOI and CIF/NIF) to be included in the shipment details. Enter these in the customs or recipient information fields before creating the label.

For InPost locker shipments in Italy, both the sender and the recipient must have a valid Italian mobile phone number registered. If the phone number is missing or incorrect, the locker will not accept the parcel. Check the recipient's phone number in the shipment details and make sure it is a valid Italian mobile number.

If your labels are being created through a connected webshop such as Shopify, WooCommerce, Odoo, or Shopware, the error may originate from the integration rather than from Sendcloud or the carrier directly. In that case, the steps above may not resolve the issue because the root cause is the connection between your webshop and Sendcloud. If you have checked all the steps above and the error only occurs for orders coming through your integration, see the troubleshooting article for your specific integration before contacting Support.

If a shipping method that previously worked is no longer available or is returning errors, check the following:

• Contract credentials: Go to Shipping > Carriers > My contracts and confirm that the credentials for this carrier are still valid. Some carriers (UPS, DHL, Poste Italiane) periodically require re-authentication. If your password or API key has changed on the carrier side, update it in Sendcloud as well.
• Contract status: Check whether the carrier has changed the service levels or routes included in your contract. If a method has been removed from your contract, it will no longer appear in Sendcloud.

If none of the above applies and the method has disappeared without any account changes, contact Support with the carrier name, the method name, and the date it stopped working.
