What is the difference between a GCP region and a zone?

A region is a specific geographic location, such as europe-west1 in Belgium. A zone is an isolated deployment area inside a region, named as the region code plus a letter, like europe-west1-b. Spreading resources across zones protects against single-zone failures.

What are GCP multi-regions?

Multi-regions such as us, eu and asia are large geographic areas that span several regions on the same continent. Storage services like Cloud Storage and BigQuery can use a multi-region to replicate data across regions for higher availability and lower cross-region latency.

Why are some regions marked low CO2?

Google publishes a carbon-free energy percentage for each region. Regions flagged low CO2 here run on a high share of carbon-free energy, which lets you reduce the carbon footprint of your workloads by choosing them. These figures change over time.

How do I list available zones with gcloud?

Run gcloud compute zones list to see every zone your project can use, or gcloud compute regions list for regions. This reference is a quick offline lookup; the live CLI is authoritative for quotas and availability.

Does this tool fetch data from Google?

No. All region data is bundled into the page and searched locally in your browser. Nothing is sent to Google or any server.

Look up any Google Cloud region or zone

Google Cloud organises infrastructure into regions (geographic locations), zones (isolated areas inside a region), and multi-regions (continent-scale groupings for replicated storage). This reference maps every commercial GCP region code to its city, continent, zone naming and multi-region membership, with a search box and continent filter so you can find the right region or zone value fast.

How it works

Each region has a code like europe-west1. Its zones are formed by appending a letter suffix, so the Belgium region exposes europe-west1-b, europe-west1-c and europe-west1-d. When you create most resources you specify a region or a single zone:

gcloud compute instances create vm-1 \
  --zone=europe-west1-b \
  --machine-type=e2-standard-2

Storage services instead accept a location, which may be a single region (europe-west1) or a multi-region (eu, us, asia). Multi-regions replicate data across regions on the same continent for durability and lower read latency.

Tips and notes

Use the search box for a city or code; the continent dropdown narrows by geography.
Pick a zone for compute, but a region or multi-region for buckets and datasets.
Spread instances across at least two zones in a region for higher availability.
The Low CO2 column follows Google’s published carbon-free-energy data and changes over time — always confirm with the live console for current figures.
