CQ zones and ITU zones are separate numbering systems with different boundaries and operating contexts. CQ zones are common in contest exchanges and some award references, while ITU zones are used in international operating references and other award workflows. The same station can have one CQ zone number and a different ITU zone number, so always match the overlay to the reference system your task uses.

Zone map FAQ
Use the static view for the fastest broad check and quick CQ-versus-ITU comparisons. Switch to interactive view when you need search, popups, or closer boundary inspection. If your starting point is uncertain, resolve location first in Grid Square Lookup, then return here to confirm zone context.
They solve different problems. Maidenhead grid squares are positional labels for distance, heading, and precise station context. DXCC is an entity and award framework. This map answers a narrower question: which CQ or ITU zone numbering reference applies in this area.
Near borders, islands, and coastal transitions, verify the actual operating position before logging a zone. Static overlays are best for fast visual checks; interactive mode is better for popups, country search, and close boundary reads.
