Problem

I have tried printing a UPS shipping label and am seeing an error returned:

120218: Missing or Invalid ShipTo tax identification. TaxID may not exceed a length of 15 

Solution

The error means the Tax Identification Number in the UPS config: Linnworks.net > Shipping > Integrations > Config is empty or exceeds a length of 15 digits. 

The Tax Identification Number value may not exceed a length of 15 digits.
