PostNord returns specific error codes when a booking fails. Here are the most common ones and how to resolve them.
"Service is not available for this destination"
The selected service code (e.g. MyPack Collect) is not available for the destination country or postal zone. Solutions:
- Try a different service (e.g. switch from MyPack Collect to Parcel)
- Check that the destination country is supported by your PostNord agreement
"Invalid service point"
The selected service point ID is not valid for the destination. This can happen if a service point has been removed since you selected it. Go back and choose a different service point.
"Weight exceeds maximum"
The parcel weight exceeds the service limit (typically 20 kg for domestic services, 30 kg for some business services). Options:
- Split into multiple packages if possible
- Choose a heavy-parcel service if available in your agreement
- Contact PostNord to arrange a custom booking for oversize items
"Missing mandatory field"
A required field for the service was not provided. Common missing fields include phone number (required for home delivery notifications) and email. Check the form and fill in the missing fields.
"Customer number not found" / "Unauthorized"
The API key or customer number is incorrect or the API key does not have access to the Shipping API. Go to Settings → Integrations and verify your PostNord credentials.
"API temporarily unavailable"
PostNord's API is experiencing downtime. Check the PostNord status page or try again in a few minutes. If the issue persists for more than 30 minutes, contact PostNord support.
