How to Fix Address Errors When Creating Shipping Labels

When creating shipping labels in Ship&co, you may encounter an error message related to the shipping address. Most of these errors are returned by the carrier’s system (FedEx, DHL, UPS, Japan Post, Yamato, etc.), not by Ship&co itself. Use this guide to resolve the most common problems.

1. Address Too Long

Error examples:

• “Address line too long”
• “Invalid field length: Street/City/Province”

Cause: Carriers enforce strict character limits for each address field. If any field exceeds the limit, the label request fails.

How to fix:

• Shorten the text in Address 1 and Address 2.
• Move apartment, suite, or building numbers to Address 2.
• Delete extra instructions, references, or repeated information.
• Remove unnecessary punctuation/symbols.
• Ask an AI agent like Claude or ChatGPT to shorten addresses (ex: Avenue: AVE, Center: CTR...)

2. Invalid City/Province/Postal Code Format

Error examples:

• “City/Province mismatch”
• “Invalid postal code format for destination country”
• “State/Province missing or incorrect”

Cause: The city, state/province, and postal code don’t match the carrier’s database, or the format is incorrect for that country.

How to fix:

• Verify the address against the destination country’s official postal format.
• Use the correct state/province code (e.g., QLD for Queensland, Australia).
• Confirm the postal code is valid for the specified city/province on Google Maps.
• Use carrier address-check tools (Like DHL Capability tool) when unsure.

3. Missing Required Fields

Error examples:

• “Phone number required”
• “Recipient email missing”
• “State/Province required”

Cause: Some carriers require additional fields depending on the route (e.g., phone, email, province/state, company name).

How to fix:

• Always include a valid phone number for the recipient. It might be used by the carrier to contact the consignee.
• Add a valid email address for cross-border shipments. It's often used by carriers to send tracking status.
• Provide state/province for countries such as the US, CA, AU, CN, and MX.

4. Invalid Characters

Error examples:

• “Unsupported characters in address field”
• “Special symbols not allowed”

Cause: Some carriers reject certain symbols, emojis, or non-Latin characters.

How to fix:

• For international shipments, use Roman alphabet characters (A–Z, 0–9) only. JapanPost International accepts also Chinese and Korean characters. But for FedEx, DHL and UPS, only roman alphabet.
• Remove symbols like #, &, /, unusual dashes, or emojis.
• For Japanese domestic labels (Yamato, Japan Post), Japanese is allowed, but avoid mixed full/half-width symbols.

5. Shipper/Warehouse Address Errors

Error examples:

• “Invalid shipper address”
• “Origin address too long”

Cause: The warehouse (shipper) address saved in Ship&co violates a carrier rule (length, format, or characters).

How to fix:

• Open Settings > Warehouses in Ship&co and edit the warehouse used for the label.
• For international shipments, enter the address in Roman characters.
• Leave Address 3 blank (FedEx doesn’t support it).
• Keep each field concise and within character limits.

6. Country/Service Restrictions

Error examples:

• “Service not available to this country”
• “Invalid destination address” (when service is unsupported)

Cause: The selected service doesn’t operate for the chosen route/country or area. Sometimes it's only temporarily, due to a natural disaster or security threats.

How to fix:

• Confirm that the carrier serves the destination country.
• Select a different service (e.g., FedEx International Priority instead of Economy).

Best Practices Checklist

• Keep each address field within carrier character limits.
• Verify city–state/province–postal code consistency.
• Always provide the recipient's phone and email for international shipments.
• Use Roman characters for international labels.
• Review your warehouse address in Ship&co settings (no data in Address 3).
• When in doubt, validate the address with the carrier’s address tools.
