# 4.3 Address (slug), subdomain and QR

1. In the **Address** card, set the **slug** (2–40 chars, lowercase/hyphens). The page lives at
   `.../p/the-slug`. The editor shows **live availability** and validates the format.
2. **Custom subdomain** (**Pro+** plans): turn it on to also serve the page at `the-slug.rezvy.app`.
   (Needs DNS/TLS on the platform side.)
3. The slug can be changed **once a week** (the editor shows the next allowed date).
4. Each store has a **direct link** and a **QR code** (the **QR** button) with **Download** and
   **Print** options — ideal for the counter, window or cards.
