Benefits of a temporary number for Zalo
- Privacy: keep your personal SIM off Zalo and away from data leaks.
- No SIM card: receive the SMS in your browser.

Activation or rental
A one-time activation keeps the number for about 20 minutes, which is enough for one Zalo code. If you expect Zalo to ask for verification again, for example when you log in on a new device, a rented number is safer because it stays assigned to you for days or months. Read more in renting vs one-time numbers.
If the Zalo code does not come
Wait 1 to 2 minutes before requesting again, check that the country code is not entered twice, and try another number or country if Zalo refuses the first one. See 10 fixes for codes that do not arrive.
Use it responsibly
Temporary numbers are a privacy and testing tool. Follow Zalo’s terms of service, do not use numbers for spam, fraud or impersonation, and keep your own SIM on accounts you must be able to recover long term.
