To ensure that we're able to deliver samples successfully, we verify the address that you enter against our database. However, sometimes there are cases where your address may fail to be recognised. The most common reason for this is if your postal or ZIP code is relatively new.

We do regularly update our database to ensure as many people's addresses can be verified. However, if you're still struggling to request your sample, we recommend entering a work address as an alternative delivery location.
