Area Code 563 — Davenport, Iowa
The code reaches 137 communities and 17 counties across Iowa.
Was this call legitimate?
The area code itself carries no risk signal. 563 is assigned to Davenport, Iowa, so a call from it is consistent with a real caller in that area — but the digits alone prove nothing, because they can be forged.
Caller ID is set by whoever places the call, not verified by the network. That is why neighbour spoofing works: an operation anywhere in the world can display a number that matches the area code — and often the first three digits after it — of the person being called, so the call looks local. Every community in the 563 territory is a plausible-looking origin for a forged 563 number, which is why one can be made to look like a neighbour to so many people.
If you did not recognise the call: let it go to voicemail — a legitimate caller with real business will leave one. Do not return the call using the number shown; look the organisation up independently and call the number you found. Never confirm personal details, card numbers, or one-time codes to someone who called you, however plausible the number looked.
Codes.zone publishes no complaint counts, risk scores, or caller identities. We hold no data on individual numbers and will not estimate what we cannot source.
Local time and when to call back

Reasonable callback window
8:00 AM – 9:00 PM
local time in Central
Federal rules bar telemarketing calls to a residence outside 8:00 AM–9:00 PM in the called party's own time zone. It is a sensible bound for a personal callback too — and a caller who rang you well outside it was not observing it.
Overlay codes
563 is the only area code serving its territory — it has no overlay in the current numbering plan for Iowa. Where a region has no overlay, a number's area code still corresponds to a single geographic area.

Prefixes inside 563
We do not publish the NXX prefixes inside 563. The assignment of prefixes to rate centres comes from LERG routing data, which is proprietary, and we will not estimate it from postal data — ZIP codes and telephone prefixes do not map onto each other. Awaiting a clean-rights NPA-NXX source.
