Last updated:
Most information you’ll find online about Samsung’s *#06# not working is outdated.
The issue was mainly reported on Galaxy devices running One UI 6.0 and earlier, where *#06# sometimes did not show the IMEI number even though the device was working normally.
On newer Samsung phones running One UI 7.0 and above, *#06# generally works normally and shows IMEI1 and IMEI2 instantly.
This guide breaks down why *#06# stops working on some Samsung devices and how to check your IMEI quickly when the code doesn’t respond.
Why Is *#06# Not Working on My Samsung Phone?
On some Galaxy devices running One UI 6.0 and earlier, Auto Blocker may stop *#06# from showing the IMEI. When it is enabled, Samsung can restrict certain service and diagnostic codes as part of its security controls.
Auto Blocker is a built-in Samsung security feature used to block risky app installs, unofficial firmware updates, and suspicious USB actions that could affect device security.
In One UI 7.0 and later, Samsung adjusted how these restrictions work, and *#06# generally functions normally even when Auto Blocker is still enabled.
If *#06# does not respond, it is usually due to software behavior or system restrictions, not an issue with the IMEI itself.
How to Find Your IMEI Without *#06#
To get the IMEI1 and IMEI2 on your Samsung phone without using *#06#, you can use the following methods.
1. From The Android Settings Menu
Go to Settings > About phone. Your device’s IMEI1 and IMEI2 will be listed directly on this screen.
2. Check the Back Sticker
Almost every Samsung phone has a sticker on its back that includes the IMEI number. This is also common on older Galaxy models or region-specific variants.
3. Check the Retail Box
The original retail box of your Samsung phone contains a label with important device details, including IMEI1 and IMEI2, serial number, and model information.

Other Samsung USSD Codes That May Not Work
The same restrictions that affect *#06# can also impact other Samsung service or test codes on some devices, especially on older One UI versions.
For example, codes like *#0*# (hardware test menu) may also fail to open on certain Galaxy devices due to system-level security restrictions.
On One UI 7.0 and later, most of these service codes work normally again on supported devices. In testing on a device running a newer One UI version, *#0*# worked as expected even with Auto Blocker enabled. However, behavior may still vary depending on the device model, software build, and region.

Should You Disable Auto Blocker to Fix *#06# Not Working?
Some guides online suggest turning off Samsung’s Auto Blocker to make *#06# work again. In most cases, you should not do this.
Auto Blocker is a built-in security feature on your Samsung phone. Disabling it reduces your phone’s protection for a problem that usually isn’t security-related.
On newer One UI versions, *#06# works normally without changing any settings. If it doesn’t work, it’s usually due to software behavior or version differences, not Auto Blocker alone.
Keep Auto Blocker enabled. Disabling it is not required to fix *#06# in most cases and only adds unnecessary security risks.
Conclusion
If *#06# is not working on your Samsung phone, it is usually due to One UI version behavior or system restrictions, not a missing IMEI.
On One UI 6 or earlier, the most reliable fix is updating the software. On newer versions, the IMEI can be checked directly from Settings > About phone without relying on USSD codes.
Some Samsung service codes may also behave differently depending on the device and software version.
