Nobody needs the house number three weeks early.
Publishing an address weeks ahead invites people to knock on the door, peer in windows, or worse. Pickerty never shows the full address right away. You decide who eventually sees it, and when.
This article covers the Address step on an in-person sale.
On the Address step, under Address visibility, you pick one of two:

Neither is selected on a new sale, so this is a choice you have to make rather than one you can skip past.
That tag is not a suggestion. If nobody can find the address without signing up, nobody can walk up on the day either. Choosing Private rules out walk-in days for the whole sale — see How people attend your sale.
Set the Date and Time the full address should appear. Until then the sale page shows the city, state, and zip only.
Pickerty suggests 9:00 a.m. the day before your first sale day. That is a sensible default: people can plan their morning, but nobody has a week to wander past.
The text underneath shows exactly what your customers will see — Everyone sees Miami, FL until September 17 at 9:00 AM. After that, the full address is shown. Double check it before you move on. It is the fastest way to catch a wrong date.

Private sales still let you control the timing, with two options:

Gated communities. HOA restrictions. Buildings with a doorman. Estates where the family has asked you to keep it quiet. High-value contents. Anywhere a stream of curious strangers would be a problem.
Hiding the address does no good if one of your photos shows the house number on the front door, or a letter with the address on the kitchen counter. Take a quick look before you publish.
