2.  Use Fastmail without SIM — no physical card needed.
3.  Fast SMS delivery — codes arrive in seconds.
4.  Zero setup — just pick a number and go.

Step-by-Step: How to Use a Free Number for Fastmail

Step 1: Go to the number list and choose any temporary mobile number for Fastmail. Make sure the country matches what Fastmail accepts for verification.

Step 2: Enter that online number for Fastmail registration into the app during sign-up.

Step 3: Wait a few seconds. The message should show up right on the page — no refresh needed.

Step 4: Copy the Fastmail verification code and complete registration.

Optional: Save the number if you plan to reuse it, or go for a temporary SIM Fastmail (paid option) for private use.

Free vs. Paid Numbers: What You Should Know

Free is good. But sometimes, getting OTP for Fastmail just doesn’t work with overused numbers. That’s when you look at paid ones.

Free Numbers

1. Shared by everyone
2. Sometimes blocked
3. Great for one-time use
4. Good for testing or throwaway accounts

Paid Numbers

1. Private & exclusive
2. Rarely blocked
3. More reliable for Fastmail OTP online
4. Ideal if you want to verify Fastmail without SIM or reuse the same line

If you’re trying to create Fastmail account without phone number that you own — this is the way.

What About Safety and Privacy?

You're not giving your real number — that’s already a win. But still:

1. Don’t use temporary numbers for banks or 2FA recovery.
2. Messages are public unless it’s a private paid number.
3. Our system doesn’t track or log your personal data.

You’re using a one-time number for Fastmail that auto-expires. Think of it as a burner phone, but digital.
