Tips for a smooth Fastmail verification
- Have Fastmail open on the screen that asks for your number before you buy, so the code window starts when you are ready.
- Wait for the app's resend timer before asking for a new code; repeated requests can get a number turned away.
- If a number is refused or no code comes, tap Cancel & refund and try another number or country. Retrying costs nothing.
Private temporary number vs free public inbox
Free public inboxes are fine for a quick test, but every code sent to them is public. A private number keeps the sign-up code to you; for an account you will log in to again, add your own number or email and turn on two-step verification right after, or rent a number.
Private number
- One buyer per number for that activation
- The code shows only in your dashboard
- Pay only if the code arrives
- For one verification, up to about 20 minutes
Free public inbox
- Shared: anyone can read the messages
- Codes sent to it are public

Fastmail number FAQ
What does a verification number for Fastmail cost?
Fastmail numbers cost from $0.20 to $2.88 today, with a median of $0.40 across 158 countries. The cheapest right now are United Kingdom ($0.20), Australia ($0.20) and Argentina ($0.20). Prices update several times a day, and you only pay if the code arrives.
Which country is best for Fastmail verification?
The cheapest well-stocked countries for Fastmail right now are United Kingdom, Australia and Argentina; if one number is turned away, try another country.
What if my Fastmail OTP never arrives?
Not every number gets a code. If yours does not, you are not charged: the price is only held while you wait, and it goes back to your wallet automatically when the timer ends. You can also tap Cancel & refund after a few minutes and try another number.
How long do I have to receive the Fastmail code?
Up to about 20 minutes per number; the timer on your number shows exactly how long. When a code comes, it usually arrives within a minute or two, but not every number gets one, because some apps turn certain numbers away. If nothing comes, the hold is refunded and you can try another number or country.
Is this a temporary number for Fastmail?
Yes, and a private one: the number is yours alone for one Fastmail verification, for up to about 20 minutes, and the code shows only in your dashboard. Free public inboxes are different: anyone can read the messages there.
Can I receive a second code or log in again later?
The number is meant for one verification within its window, so finish signing up in one go. If you need to log in again later or receive codes over weeks, rent a number instead.
Why does Fastmail say the number is not valid or blocked?
Apps sometimes turn away certain number ranges, even real SIM numbers. If that happens, tap Cancel & refund and get another number or pick a different country. You are not charged for a number that never received a code.
Are these real SIM numbers?
Most of our numbers are real SIM numbers, and a few are virtual. If an app refuses a number, cancel it for a refund and try another country.
How do I pay?
Create a free account, then top up your wallet from $10 by card, crypto or the other methods shown at checkout. Numbers are paid from that balance, and unused balance stays for later numbers: it never expires, but it cannot be withdrawn. The price is held when you take a number and only charged once the Fastmail code arrives.
Is it allowed to use a virtual number for Fastmail?
Use our numbers only for your own accounts, and follow Fastmail's terms and the law where you live. Temp Number is not affiliated with Fastmail.
