It means: “What all do I need to say about my street, city, etc.?” In a mail- delivery context, it’s asking what address details are required.

What to include

Usually you should provide:

  • Your full name.
  • Street name and house number.
  • Apartment/unit number, if you have one.
  • City or town.
  • Postal code.
  • Country, if it’s an international shipment.

Why it matters

Mail services use those details to route and deliver the item correctly, and incomplete or incorrect address information can delay or prevent delivery. Some systems also ask for extra contact details like a phone number or email, especially for delivery updates or if the courier needs to reach you.

Simple example

A typical format looks like:

  • Name
  • Street 123
  • Apt. 4B
  • City, ZIP code
  • Country

In plain Czech

A natural paraphrase would be: “Co všechno mám napsat o své ulici, městě a podobně pro doručení pošty?” The key idea is just “address details.”

TL;DR: It’s asking for the full delivery address, not just the street or city alone.
