Why Steam verification rejects so many numbers
Steam requires phone verification to protect high-value game libraries, combat cheating, and secure trading. But many numbers are rejected:
- •VoIP Hard Block: Steam explicitly states VoIP numbers "do not meet security requirements" and cannot be used for Steam Guard Mobile Authenticator setup
- •"Number Already Used" Errors: Steam flags numbers previously used on multiple accounts, preventing signup with shared temporary services
- •CS2 Prime Requirements: Counter-Strike 2 Prime Status ($14.99) requires phone verification to combat cheating—VoIP numbers are rejected to maintain competitive integrity
- •Trading & Marketplace Locks: Steam Guard Mobile Authenticator requires a valid phone for trading confirmations and marketplace access—without it, you face 15-day trade holds
- •SMS Delivery Failures: Users report Steam verification codes not arriving on virtual numbers, leaving accounts unprotected
- •Account Recovery Risk: Without a verified phone number, recovering a hacked Steam account with thousands in games becomes nearly impossible
Your Steam library represents years of purchases—$500, $1,000, even $5,000+ in games. If you can't verify your phone for Steam Guard or CS2 Prime, you risk account theft, trade restrictions, and competitive disadvantages.

Important notes for Steam verification
Not affiliated with Steam or Valve Corporation. JoltSMS provides phone numbers for legitimate account verification only—not for circumventing Steam account suspensions or VAC bans.
Best practices:
- Set up your JoltSMS number BEFORE purchasing CS2 Prime or enabling trading to avoid delays
- Enable Email, Slack, Telegram, and Microsoft Teams notifications so verification codes reach you instantly even when away from your computer
- Keep your number active long-term—Steam may require re-verification during device changes or account recovery
- Test your number with a non-Steam SMS first to confirm delivery is working properly
- Use a fresh dedicated number per Steam account to avoid "number already used" errors
- For high-value inventories (expensive CS2 skins, rare items), dedicate one JoltSMS number exclusively to that account
- JoltSMS numbers are US-based; Steam may have regional verification requirements for non-US accounts
- Numbers are for legitimate account verification only—not for circumventing Steam account suspensions or VAC bans
- Steam limits how many accounts can use the same phone number—use one JoltSMS number per Steam account
- Initial number provisioning takes 24-48 hours—plan ahead before purchasing CS2 Prime or enabling trading
- While real-SIM numbers have the highest acceptance rate for Steam, we cannot guarantee acceptance on any platform
- Steam Guard Mobile Authenticator requires the Steam mobile app in addition to phone verification
- Also works for <a href="/platforms/epic-games-verification-number" class="text-blue-600 hover:text-blue-800 underline">Epic Games verification</a> and <a href="/platforms/riot-games-verification-number" class="text-blue-600 hover:text-blue-800 underline">Riot Games verification</a>
Steam verification FAQ
Yes. JoltSMS provides real-SIM, non-VoIP US numbers from major carriers (T-Mobile/AT&T). Steam explicitly blocks VoIP numbers but accepts real mobile numbers. Our Real-SIM numbers pass Steam's verification checks because they're physical SIM cards from legitimate carriers, not virtual/VoIP services like Google Voice.
