Here at Auto Trader, we have a database of UK postcodes which get updated regularly. This allows us to calculate search distances.
When you are creating an advert, you may come across issues in entering your postcode if the following applies:
- You live in a new build and the new postcode is not on our system yet
- The postcode is not in the UK
If this is the case, you will see an error in red saying, 'Please enter a valid UK postcode'
How to fix this
- If you live in a new build we would advise that you chose another postcode close by. As a private seller, we do not show your exact location on the advert so this will be fine.
- We cannot post an advert without a valid UK postcode, if you live outside the UK you will need to use the postcode of the person selling your car in the UK.
