Postalcode was seen to be masked since yesterday for FindingService API for operation-name findItemsAdvanced. The postalcode was seen as-is before. Any means of getting the as-is postalcode through eBay FindingService API ?
I've also seen this issue recently when using the ebay API.
Most annoyingly It seems ebay have changed their policy for sharing presale information - possibly due to their interpretation of data protection.
The issue is discussed with reference to the ebay UI here: https://community.ebay.co.uk/t5/Buyer-Central/Buyers-can-no-longer-see-sellers-postcode-on-any-item-WHY/td-p/6249678
