Dear Master Robert Lee,
Re: house numbers, I read a reply to a similar question where you had mentioned that for e.g., if the unit number is 01-22, then means 01 is the floor level, while 22 is the unique apartment number.
Where I live, house numbers usually have the floor level included, e.g., if house no. is 501, the 5 is the floor level.
So, should I enter the numbers as 05-501, or just 501 in the second box?
Because the interpretations vary greatly.
Please do advise.
Many thanks!

Dear Anon,

Yes, since 5 represents the floor level, you should enter it as #05-xxx. If your unit happens to be#05-01 (where 5 represents the level) and each of the units in a block are : 01, 02, 03, 04, 05, 06, 07 then should enter the numbers thus as #05-01. Alternatively, if your unit does not follow the above number arrangements then you may have to enter it as #05-501.

Warmest Regards,
Cecil
