What Do Zalo's Terms Say About Multiple Accounts, Devices and Third-Party Software?

What do Zalo's terms say about multiple accounts? #

Zalo does not forbid them in one sentence, but it clearly limits them. Its Service Agreement limits both the number of accounts a person may register and the number of devices an account can be signed in on at once, and its community policy repeats that personal accounts per user are limited. None of the pages read on 3 October 2026 states a number.

This article summarises three sources: the Service Agreement (effective 5 September 2026, last updated 28 August 2026), the community policy (the version in force since 13 October 2023) and Help Center pages. It is a summary, not legal advice, and all three are in Vietnamese, so read the full text before making a decision.

What each Zalo document says #

One detail is easy to miss. Zalo's "account does not exist" help page says an account inactive for 45 days is permanently deleted and cannot be restored. Clause 3.2 is softer and says Zalo may take suitable measures. The two pages do not match exactly, so treat 45 days as a hard deadline.

How Zalo checks and what it can do #

Clause 14.1 says Zalo runs two moderation systems side by side: a team of human moderators and automatic moderation using machine learning and artificial intelligence. Clause 14.2 lists measures it may apply, one or several, depending on the nature, severity and consequences of the violation:

• a notice of the violation and a demand to stop;
• a request for identity verification;
• removal of the violating information or content;
• feature limits, a temporary lock or a lock on the account.

The Help page on a temporarily disabled account says you then cannot use Zalo on a computer for the time being and some phone features are limited. It also says you can be locked if you use false or non-owner information.

Using several accounts and still staying inside the rules #

• Only accounts you own or are authorised to manage, registered with lawful phone-number information, which Zalo says its accounts must use.
• Only Zalo's own apps and website. No software that signs in for you, sends messages automatically or emulates a device.
• One sign-in place per account, such as Zalo PC for the main account and a browser profile per Zalo Web account. See two Zalo accounts on one computer.
• No buying, selling or swapping accounts, and no accounts posing as other people.
• No high-frequency posting, sharing or interacting. Zalo prohibits it whether done by hand or automatically.
• Keep accounts active so they never reach the 45-day mark, and link an email and switch on two-layer security.
• Brands and sales teams: use a Zalo Official Account with several admins instead of one shared personal account. See Official Account admins and roles.

If an account is restricted or locked: steps and appeal routes #

1. Read the notice and complete verification if Zalo asks. Zalo describes a face-and-voice check with a result in 2 to 5 working days.
2. If verification fails repeatedly, contact Zalo through the Contact page on help.zalo.me.
3. Send a complaint through an official channel: the hotline 1900 633 155, hotro@zalo.me or feedback@zalo.me, or the support official accounts Zalo Hỗ Trợ Android and Zalo Hỗ Trợ iOS inside the app. Clause 14.3 gives you the right to complain to explain yourself or ask Zalo to reconsider.
4. Include account or contact details, what the complaint is about, when it happened and any evidence.
5. Note the timing: Zalo confirms receipt within 3 working days and normally handles complaints within 30 working days of receiving all the information.

The complaint page describes a process and time limits, and it does not promise any outcome. Do not treat a new account as a way around a restriction: the route Zalo describes is verification first, then contacting support or appealing. The warning screens and verification steps are covered in the article on logouts and unfamiliar-device warnings.

Where ADSSPEED fits #

ADSSPEED is a desktop app for Windows and macOS that manages many browser profiles. Each profile keeps its own cookies, local data and browser settings, and a proxy can be set per profile.

Zalo's rules on third-party software, emulated devices and false accounts apply to every tool, browser profiles included. Operate chat.zalo.me by hand, with no tool that signs in or sends messages automatically. Use only accounts you own or are authorised to manage, and follow Zalo's rules. ADSSPEED is not affiliated with Zalo.
