Renting a virtual number: what you actually get
Quick answer
Renting a virtual number means you use a number you don't own for a set time. Short-term rentals, like Noir SMS's 20-minute numbers, are made to receive one verification code and cost little. Long-term rentals give you a number for weeks or months, usually on a subscription, for ongoing texts and calls. Pick short-term for a one-time sign-up and long-term, or your own number, for accounts that will need the number again.
"Rent" sounds like a lease, but in the virtual number world it can mean anything from twenty minutes to a year. The length decides what the number is good for.
Short-term vs long-term rental
| Short-term (minutes) | Long-term (weeks/months) | |
|---|---|---|
| Best for | One verification code | Ongoing texts, re-verification |
| Cost model | Pay per number | Subscription |
| After it ends | Number is recycled | Kept while you pay |
| Recovery use | Not suitable | Possible while rented |
What a Noir SMS rental includes
- A number reserved for 20 minutes for one service.
- Automatic refund if no SMS arrives, and manual cancel after 2 minutes.
- Free extra SMS from the same service while active. SMS only, no calls.
After a short rental
Add your own number, an email and an authenticator app to the account, so it doesn't depend on a number that will belong to someone else later. Use rentals only for your own legitimate accounts.
