What Google expects from a number
Before you buy anything, this is what has to be true of the line for Google to accept it.
A real cellular number not already at Google's reuse limit for other accounts.
Clarity on whether the number is filling the recovery-number or the 2FA-number role, since Google's settings treat them separately.
For Workspace, a number that passes the stricter organizational verification, not just a personal-account check.
Ability to receive either an SMS code or an automated call, since Google offers both delivery methods.
Why numbers get rejected on Google
Most failures are one of these, and knowing which one you have hit decides whether retrying helps or wastes another attempt.
Google caps how many different accounts a single phone number can verify within a given period, so a number that's already backed several signups gets rejected regardless of its type.
A recovery number and a 2FA (two-step verification) number serve different purposes in Google's account settings, and confusing the two during setup causes the wrong prompt to appear.
Google Voice numbers are themselves a Google product, but they're VoIP under the hood and can still be rejected as the verification number for a separate new account — being a Google service doesn't exempt it from the VoIP check.
Workspace admin-console verification runs a stricter check than a personal Gmail signup, since it's tied to a paying organization rather than a single free account.

Frequently asked questions
How many Google accounts can I verify with one number?
Google limits how many separate accounts a single phone number can be used to verify within a given period — it doesn't publish the exact figure, and it can vary. If a number that previously worked suddenly gets rejected with no other explanation, reuse across too many accounts is a common, quiet cause.
What's the difference between a recovery number and a 2FA number on Google?
A recovery number is what Google uses to help you regain access if you're locked out — a fallback contact method. A 2FA (two-step verification) number is an active security layer that receives a code at every sign-in from a new device. The same number can technically fill both roles, but they're configured separately in your account's security settings.
Does Google reject its own Google Voice numbers for verification?
It can. Google Voice is a VoIP service, and Google's own verification systems apply the same carrier-type checks to it as they do to any other VoIP number — being a Google product doesn't exempt it. This is a common source of confusion, since it feels like it should be trusted by default.
Can I create a Google account without a phone number at all?
Google generally pushes phone verification during signup, especially for new or higher-risk-looking accounts, and it's not something you can reliably opt out of on request. A real cellular number is the more consistent path through that step than trying to skip it.
Is verification stricter for Google Workspace than for a personal Gmail account?
Yes, generally. Workspace accounts are tied to a paying organization and an admin console, and Google's checks for that tier tend to be more deliberate than a free personal-account signup. A number that sailed through a personal Gmail signup isn't automatically guaranteed to clear a Workspace admin verification the same way.
