Users of the Xiaomi ecosystem often face the need to identify their profile, especially when trying to unlock a device after a reset or when restoring access to cloud data.Mi ID is a unique digital ID that is assigned to each user when you register. Unlike an email address you create yourself, this number is generated automatically by the system and serves as a key to your personal data.
Many people confuse the concept of "account number" with a phone number associated with a profile, or with the IMEI of the smartphone itself. These are different values, and each of them performs its function in the Mi Account security system. If you need to restore access to a blocked gadget or prove ownership of a profile in support, knowing the exact ID becomes critical. In this article, we will discuss in detail all the ways to obtain this information.
There are several methods of obtaining data: through the settings of a working device, through an official website or by analyzing notifications from the system. It is important to understand that access to this information can be limited if the device is lost or in a Factory Reset state. In such cases, alternative methods of verification come to the rescue, which we will also discuss below.
Differences between Mi ID, UID and Phone Number
Before you start searching, you need to clearly distinguish between the concepts, because the terminology can vary between the interfaces of the different versions of MIUI and HyperOS. Mi ID is the main identifier, often a long number or combination of characters, which is used for internal identification in the company's databases.
At the same time, the UID (User ID) can be found in logs or when debugging applications, but for the average user, the main reference is exactly the Mi ID or the associated phone number. The phone number, in turn, is often used as a login, but is not an internal account number in the global system.
⚠️ Note: Never give a confirmation code (SMS), Xiaomi support staff never ask for codes from your number. SMS login.
Understanding these differences will help you navigate the settings menu more quickly, and if you’re looking for information to fill out a support form, you’ll likely be asked to specify the Mi ID or email used to sign up.
Why can numbers differ on different devices?
Search for ID through smartphone settings
The easiest and fastest way to find out your data is to use the Xiaomi smartphone or tablet itself, if you have access to it with a profile login.
For devices based on MIUI 12-14 and HyperOS, follow the following steps:
1. Open the Settings app.
2. At the very top of the list, click on the line with your name and avatar (Mi Account section).
3. In the menu that opens, look for the ID or Mi ID field. It is usually located under the username or in the About section inside the account menu.
☑️ Checking the data in the menu
In some versions of the firmware, the number may be hidden, in which case click on the gear icon in the corner of the screen or select Security → Account Settings, which often displays complete technical information, including the UID and the date of the profile creation.
💡
Take a screenshot of a page with a Mi ID and save it to the cloud or on your computer, which will help you quickly find a number if your phone is lost or locked.
Using the web version of Xiaomi account
If the smartphone is not available, but you remember the username and password, the only option is the official portal i.mi.com. This method allows you not only to see the number, but also to manage the associated devices, find them on the map or remotely erase data.
For information, log in to the site using your email or phone number. Once you have successfully logged in, the system will redirect you to your personal account. The top right corner or the center block of Profile displays basic information. Look for the Mi Account ID line.
The web version may not be as informative as the mobile app, but if you go to Settings → Security, you can see more detailed session and associated device data, which may also feature a unique identifier.
| Access method | Where to find | Required data | Availability |
|---|---|---|---|
| Phone settings | Top menu line | Unlocked screen | Always (at the entrance) |
| I.mi.com | Personal office | Login and password | Any PC. |
| Security Annex | Account tab | Access to the system | Depends on the version. |
| Checks and letters | Email archive | Access to the post office | Historical data |
The web interface is especially useful when checking which devices are currently logged in to your profile, allowing you to identify suspicious activity and, if necessary, terminate other people’s sessions.
Search through email and purchase history
Often users forget that the system automatically sends notifications when registering or important changes to the profile.Inbox search is an effective way to find Mi ID without accessing the phone.
Go to the mail that may have been used to sign up. In the search bar, type in keywords like "Xiaomi", "Mi Account", "Welcome" or "Registration". The greeting letter usually contains a line like "Your ID: 123456789".
It is also worth checking the Spam folder or archive folders if it has been a long time since registration. Emails from the Mi Cloud service or notifications about the purchase of equipment in the official store may also contain the buyer's ID, which often coincides with the account ID.
⚠️ Note: If you are using a third-party email client, make sure the sync works correctly.Sometimes old emails can be deleted when the inbox is overflowing.
This method is especially relevant for those who have registered an account for a long time and did not keep notes in a notebook, the electronic trail remains forever, unless you yourself deleted the correspondence manually.
What to do if access to your account is lost
The situation where the phone is blocked with the message "This device is locked to Mi Account" and access to the data is lost is the most difficult, in which case the standard methods will not work, since the security system requires authorization.
The only legal way to recover is to contact Xiaomi’s official support team, and you’ll need to prove ownership of the device.
- 📄 Original smartphone box (with a sticker containing IMEI and serial number).
- 🧾 Check for purchase of the device (paper or electronic).
- 🆔 Passport data of the owner (must coincide with the data when buying, if they were specified).
- 📱 The locked device itself (for reconciliation) IMEI).
The unlocking process takes anywhere from a few days to two weeks, and employees check documents and, if successful, untie the device from the old account, and then you can create a new profile or restore the old one, if you remember the data.
💡
Without a check and a box, it's almost impossible to restore access to a blocked Mi Account.
Security and protection of personal Mi ID
Knowing where to find your account number is important to know how to protect it, as Mi ID is the key to your digital life: photos, contacts, notes and even bank details (if you have a payment set up), which, when leaked, combined with other data, can lead to hacking.
It is recommended to check the list of trusted devices regularly. If you sell a phone or tablet, be sure to complete the data cleanup and log out before transferring to a new owner. Just resetting is not enough - you need to break communication with the cloud.
Use two-factor authentication. Even if someone learns your password, without the code from an SMS or an authenticator application, they won't be able to log into the profile. This is standard security practice that you can't ignore.
