Google verification can be stricter than other services, so the safest workflow is to test live numbers and switch quickly when a number is rejected.
Browse temporary phone numbers and live SMS inbox pages for Google verification flows and one-time code checks.
Some temporary numbers can work, but Google applies stricter checks than many other services.
Google often filters shared, recycled, or overused numbers more aggressively.
Try a different active number or switch to another country page instead of reusing the same failed number.
