Keep your personal number private
Your real phone number never touches Backblaze. Use a virtual number for full privacy.
Need to get a Backblaze SMS verification code without giving up your personal number? You can use a temporary virtual number from platforms like SMSPin to receive codes instantly and securely. This guide explains how to get your code, troubleshoot delivery issues, and maintain privacy during account setup and two-factor authentication. Keep your personal SIM off marketing lists and protect your backup data.
Backblaze SMS verification confirms you control a phone number by sending a 6-digit OTP to that number during signup or login. With SMSPin you receive that code on a temporary virtual number online โ no physical SIM card needed and your production workflows stay separate.

Four steps โ from picking a number to a verified Backblaze account.
Choose a temporary number from a provider like SMSPin. Ensure it's from a country supported by Backblaze, such as the USA or UK.
Enter the chosen virtual number into Backblaze's phone field when prompted for verification or 2FA.
Request the SMS code from Backblaze.
Refresh the inbox of your temporary number provider. Most codes arrive within 30 seconds.
Use the received code to complete your Backblaze verification. If no code arrives, use a fresh number from a different country.
SMSPin is provided for legitimate privacy and convenience use cases only. Please review Backblaze's terms before use.
Need a specific country code for your Backblaze verification? We've got you covered.
Every SMSPin number is a legitimate, carrier-registered mobile number โ not a VoIP range. Backblaze accepts them reliably.
Sign up with email only. Your real number and identity stay private.
The moment Backblaze sends your OTP, it appears in your dashboard โ pushed, not polled.
If a code doesn't appear, try a new, unused temporary number. Numbers previously used for Backblaze might be slower or blocked.
Allow up to 60 seconds before resending the code, as Backblaze limits resend intervals to prevent spam.
Temporarily disable any VPN or proxy services, as they can interfere with SMS delivery.
Consider using a number from a different country, like the USA or UK, which often have higher success rates.
Feature | Free Number | Pay-Per-Code (Activation) | Rental Number |
Backblaze SMS | High failure rate, often blacklisted | Pay only if code arrives | Continuous access, fixed fee |
Best For | Casual testing | One-time verification | Ongoing 2FA, long-term access |
Privacy | Lower, numbers overused | Higher than free | Highest for sustained use |
SMSPin Price | Free | Starts at $0.01 | Starts at $0.01 per day |
Always include the correct country code when entering the temporary number into Backblaze.
USA numbers typically require a +1 prefix, while UK numbers often use +44.
Ensure the virtual number format matches what Backblaze expects to avoid rejection.
Yes, as long as you're using it for legitimate account setup or recovery. SMSPin is not affiliated with any app or website. Please follow each app's terms and local regulations.
The number may have been reused too many times, Backblaze may have blocked short codes from that carrier, or you entered the wrong country code. Try a fresh temporary number from a different region.
You can, but for ongoing 2FA you'll need a rental number that stays active. One-time numbers expire after the code arrives, so you'll need to re-verify each time.
Avoid temporary numbers for banking, government services, or any account where you need guaranteed long-term SMS recovery. Stick to disposable services for apps like Backblaze with fallback recovery options.
Wait 60 seconds and resend. Then switch to a new temporary number from a different country. Finally, turn off VPNs or proxies that might interfere with SMS routing.
Free numbers often fail because they're overshared. Paid numbers from SMSPin have higher acceptance rates since they're less likely to be blocked by Backblaze.
Use Backblaze's backup codes or email recovery to regain access. Always save backup codes during setup when using a disposable SMS solution.
Backblaze sends a 6-digit numeric SMS code when you create an account, reset your password, or set up two-factor authentication. It's their way of making sure you're really you before unlocking your cloud storage. Without entering that code, you're stuck outside your dashboard with no way to restore files or manage backups.
The SMS prompt appears immediately after you enter your email and password; a new code is required each session.
No phone verification? No dashboard access. Simple as that.
You can use a Backblaze SMS verification temporary number to get that code while keeping your real number hidden.
Codes usually arrive within 10โ60 seconds, though short-code filtering can occasionally slow things down.
Grab a temporary number from SMSPin to receive your Backblaze code without exposing your personal SIM.
If the code doesn't show, try a fresh number from a different country; USA numbers tend to work best.
For ongoing 2FA, rent a number for a week or month so you don't have to re-verify every time.
Always save those backup codes during setup. Trust me, you'll thank yourself later.
Getting a Backblaze SMS verification code with a temporary number is almost too easy. Pick a virtual number from a platform like SMSPin, drop it into Backblaze's phone field, and wait for the code to land in the platform's inbox. Your personal number stays completely out of it.
Choose a temporary number from a country where Backblaze supports SMS verification (e.g., the USA, the UK, or many others).
Copy that number into Backblaze's SMS prompt and hit "send code."
Refresh the temporary inbox; most codes show up within 30 seconds.
Use a pay-per-code service so you only spend money when a code actually arrives.
If your code isn't showing up, first double-check the number you entered. Sometimes Backblaze blocks numbers that have been reused too often. Other times, your carrier or VPN is blocking short codes. A fresh temporary number from SMSPin usually solves this instantly.
Make sure the temporary number hasn't been flagged by Backblaze before use a newly issued one.
Wait 60 seconds before requesting again; Backblaze limits resend intervals to reduce spam.
Disable your VPN or switch servers if you're using one; it can interfere with SMS routing.
Still stuck? Try a number from a different country, like the UK instead of the USA.
Backblaze lets you use SMS for two-factor authentication, sending a code every time you log in from a new device. You can enable this in your account security settings using a virtual number. It adds a nice layer of privacy since the code goes to a disposable line instead of your personal SIM.
Head to Backblaze's Account Security page, enable 2FA, and pick SMS as your delivery method.
Enter a temporary number from SMSPin, confirm with the code, and keep the session active.
For ongoing 2FA, consider renting a number that stays active for a week or longer.
After setup, Backblaze gives you backup codes; save them somewhere safe in case SMS fails down the road.
SMSPin is not affiliated with any app or website. Please follow each app's terms and local regulations.
SMS verification ties your backup access to a phone number. Backup codes give you a recovery path without needing a SIM at all. If you don't want your real number linked to Backblaze, using a virtual number for SMS is the cleaner play. Backup codes are a fallback, not a replacement.
SMS verification is mandatory during initial setup; backup codes are optional for later recovery.
A virtual number limits how much personal data Backblaze has on you.
Backblaze recommends backup codes for recovery but won't let you skip SMS entirely.
Pairing a temporary SMS number with backup codes gives you the strongest privacy setup.
Want your code fast? Use a freshly issued temporary number from a country Backblaze recognizes, and request the code during off-peak hours. SMSPin auto-refreshes the inbox, so you'll usually see the code within 15โ30 seconds. Avoid numbers that have already been used for Backblaze; they're slower.
Start with a USA number; it has the highest success rate for Backblaze.
Hit SMSPin's "Get SMS" button to trigger a fresh request, and keep the inbox open until the code arrives.
If it's delayed, cancel the number and pick a new one. Virgin numbers get faster responses.
For ongoing needs, rent a number so you don't deal with repeated activation delays.
If you need more than a one-time code, renting a number for a day, week, or month gives you continuous access. This is great for maintaining 2FA on a backup account or for repeatedly testing Backblaze integrations. SMSPin offers rentals starting at $0.01 per day, with automatic refunds if no code is received.
Rent a number from SMSPin's "Rent" section and use it for Backblaze across multiple sessions.
Rental numbers keep the same identity throughout, so no re-verification headaches.
Perfect for developers testing Backblaze's API or anyone needing a steady 2FA line.
Way cheaper than buying a separate prepaid SIM for a single use case.
Disposable SMS is great for initial verification and casual recovery but not for an account you plan to use for years. Once you toss the number, you can't receive password reset codes months later. For long-term accounts, rent a number or lean on backup codes.
Disposable SMS works well for one-time Backblaze setup or testing without commitment.
Lose access to the disposable number? Recovery gets harder; Backblaze may fall back to email.
Keep those backup codes handy to skip SMS later.
For ongoing recovery, a rental is safer than a pure disposable option.
Backblaze supports phone verification from many countries, but there are gaps in parts of Africa and Southeast Asia. A virtual number from a covered country like the USA, UK, or India avoids those gaps entirely. SMSPin offers numbers from 25+ countries so you can verify even if your local carrier isn't supported.
Check Backblaze's list of supported countries; it often excludes smaller markets for SMS verification.
Temporary numbers from the USA or the UK usually work, no matter where you are physically located.
Use SMSPin's country filter to pick a covered region before starting verification.
If the first country fails, try another. Freshness matters more than location.
Using a temporary number means your real phone number never ends up in Backblaze's database or gets shared with third parties. That matters because Backblaze may use phone data for account recovery prompts. A virtual number keeps that exposure contained.
A virtual number stops Backblaze from linking your personal SIM to your backup files.
Privacy-conscious users should avoid tying real numbers to any cloud storage provider.
SMSPin's numbers aren't tied to your identity, so no personal data leaks through SMS.
A disposable setup also blocks SMS-based phishing aimed at your personal line.
