For units it can be a bit tricky as not all apartment blocks follow the same format. The easiest way to find out the format of your block is to type in just the street number and name and see what appears. For example if your apartment is 308 / 90-99 Smith St you can type in 90 – 99 Smith St and be able to see the format (U308 / 90-99 Smith St for example). If you still cannot find your property, please contact us on support@humaniti.com and we will look into it further.
