Google Tests Reduced Free Cloud Storage for New Accounts, Ties Access to Phone Verification

Google has begun a limited‑region trial that trims the free storage quota for brand‑new accounts from the historic 15 GB down to 5 GB. The restriction is lifted only after the user links and verifies a phone number, at which point the full 15 GB becomes available.

What the rollout looks like

• Initial allocation: 5 GB of Google Drive, Gmail, and Photos storage.
• Unlock condition: Verification of a mobile number via SMS or voice call.
• Final allocation: 15 GB once the number is confirmed.
• Geographic scope: Currently limited to a handful of markets where Google reports high rates of disposable‑account abuse.

The change was first reported by a Reddit user who received the notice during the account‑creation flow. Google’s public support pages still list the 15 GB figure, indicating the test is not yet reflected in official documentation.

Why tie storage to phone verification?

1. Spam and abuse mitigation – Disposable accounts are a common vector for phishing, comment spam, and automated scraping. Requiring a phone number adds a friction point that raises the cost of mass‑account creation.
2. Recovery and security – A verified number serves as a two‑factor recovery channel, reducing the likelihood of permanent loss of access and limiting the value of stolen credentials.
3. Data‑policy enforcement – With a verified identity, Google can more reliably enforce its terms of service, especially around content that violates policy.

Potential revenue implications

The 15 GB free tier has been static for years, while average user data footprints have grown dramatically. A 5 GB cap makes the storage ceiling visible much sooner:

• Average smartphone photo library (2024): ~25 GB.
• Typical backup size for a family of four: 40‑60 GB.
• Conversion threshold: Users hitting the 5 GB limit are likely to encounter “storage full” warnings within weeks, prompting a click‑through to Google One plans that start at 100 GB for $1.99/month.

If the test shows a measurable uptick in paid conversions, Google may roll the policy out globally, effectively shifting a larger portion of its free‑user base into the paid tier.

Regional testing strategy

Targeting regions with known high rates of fake accounts (e.g., parts of Southeast Asia and Eastern Europe) lets Google collect data on:

• Verification completion rate – How many users actually provide a phone number.
• Abuse reduction – Change in spam‑related incidents per million accounts.
• Paid‑plan uptake – Incremental revenue per user compared to a control group with the traditional 15 GB free tier.

By isolating these variables, Google can model the trade‑off between user friction and revenue gain without exposing the entire ecosystem to a potentially unpopular change.

User experience considerations

• Transparency: Users see a clear prompt that linking a phone number unlocks the remaining 10 GB. The messaging emphasizes security and recovery benefits, which may soften resistance.
• Privacy concerns: Some users may balk at sharing a phone number due to tracking fears. Google will need to assure that the number is used solely for verification and recovery, not for ad targeting.
• Alternative verification: The current test does not appear to offer backup options such as hardware security keys or email‑only recovery, which could limit accessibility for users without reliable mobile service.

Outlook

If the metrics from the pilot indicate a net positive—lower abuse rates, higher paid‑plan conversion, and acceptable user satisfaction—Google is likely to extend the policy worldwide. Existing users will retain their 15 GB, but new sign‑ups will face a two‑step onboarding process that could become the new baseline for free cloud storage.

Key numbers to watch:

• Verification completion percentage (target >70 %).
• Reduction in disposable‑account creation (target >30 % drop).
• Incremental Google One subscriptions per 1,000 new accounts (target >5 %).

For now, the change remains a regional experiment, but the combination of security hardening and revenue potential makes it a significant development for anyone relying on Google’s free cloud ecosystem.
