[POSTNORD] Unable to allocate id for this basicServiceCode: 18, from country: XX, to country: XX and customer number: XXXXXXX |

The error:

Unable to allocate id for this basicServiceCode: 18
from country: XX
to country: XX
customer number: XXXXXXX

means PostNord does not support that service for the route you are trying.

1️⃣ What service code 18 means

18 = PostNord Parcel (B2B).

This service is mainly used for business shipments within supported PostNord countries (Nordics / Europe).

2️⃣ Why your request fails

Your shipment:

FROM: XX (Different country)
TO:   XX (Europe)
SERVICE: 18

PostNord does not operate shipments from non Europe countries. Their API mainly supports:

• Nordic countries (DK, SE, NO, FI)
• Some EU countries for export agreements.

So the API cannot allocate an ID for that route → hence the error.

3️⃣ Correct service codes (common ones)

But these only work when origin country is supported (DK/SE/NO/FI etc.).

4️⃣ What you should do

Check the sender country in your request:

• If you are shipping from Europe → anywhere
  → 18 can work.
• If you are shipping from Non-Eurpian → Europe
  → PostNord API cannot be used.

Instead you must use a different carrier:

• DHL
• FedEx
• UPS
