Content (please ensure you mask any confidential information):

In 25B, we observed that V2 address block will be defaulted and we have to run OSCS scheduled process before this. We ran the process and while testing address block we are selecting address line 1 from auto suggestions which inturns city, county and postcode also auto populated based on the address line 1 selection.

However, when candidate is trying to submit the application, system is restricing stating postcode should be in correct format.

Do we need to do any additional setup for addresses in Core to magage postcode issue or candidate has to look into postcode and manally correct the same. Customer is UK based.
