Purchasing a second-hand Samsung phone can be a cost-effective way to enjoy the latest technology without breaking the bank. Whether you are buying a Refurbished Samsung S20 FE 5G, Refurbished Samsung S21 Plus 5G, or any other model, knowing the manufacturing date of the device is crucial. The manufacturing date provides insights into the phone’s age, potential battery life, and warranty validity. In this blog, we’ll explore various methods to determine the manufacturing date of a second-hand Samsung phone and give you practical tips for ensuring that your purchase is safe and reliable.
Why Knowing the Manufacturing Date is Important
Before diving into the methods, it’s essential to understand why the manufacturing date matters when buying a second-hand Samsung phone:
-
Battery Health: Lithium-ion batteries degrade over time. A phone manufactured several years ago might have a battery that has lost a significant portion of its original capacity, even if the device looks new.
-
Warranty and Support: Samsung typically provides a one-year limited warranty from the date of purchase. Knowing the manufacturing date helps you understand whether the device is still covered or if you need to invest in additional warranty options.
-
Software Compatibility: Older devices may not support the latest Android updates or security patches. Checking the manufacturing date ensures your phone can receive necessary updates.
-
Avoiding Scams: When buying second-hand or refurbished devices, sellers sometimes misrepresent the age of the phone. Verifying the manufacturing date can protect you from overpaying for an older model.
Method 1: Check the IMEI Number
One of the most reliable ways to determine the manufacturing date of a Samsung phone is through the IMEI (International Mobile Equipment Identity) number. Every mobile phone has a unique IMEI, which contains information about the device, including its origin and manufacturing date.
Steps to Check the IMEI:
-
Dial
*#06#on your Samsung phone to display the IMEI number. -
Note down the 15-digit IMEI number.
-
Visit a trusted IMEI checking website, such as IMEI.info, and enter the IMEI number.
-
The website will display details about your device, including the manufacturing date or production week.
This method works for almost all Samsung models, including Refurbished Samsung S20 Plus, Refurbished Samsung Galaxy Note 20 Ultra 5G, and Refurbished Samsung S21 FE 5G.
Method 2: Using Samsung’s Secret Code
Samsung phones have a hidden diagnostic menu accessible via a secret code. This menu can reveal detailed information about your phone, including its manufacturing date.
Steps:
-
Open the Phone app on your Samsung device.
-
Dial
*#12580*369#. -
You will see a menu displaying firmware, hardware, and manufacturing details. Look for fields like “Manufacture Date” or “Production Date.”
This method is quick and does not require any third-party websites. It’s especially helpful when buying second-hand or refurbished phones from local sellers.
Method 3: Check the Box or Warranty Card
If the second-hand Samsung phone comes with its original packaging or warranty card, the manufacturing date is often printed on it. Look for labels that include terms like:
-
“Manufactured on”
-
“Made in” followed by a date or code
Even refurbished phones, such as Refurbished Samsung S20 FE 5G, often retain their original manufacturing labels, which can give you accurate information about the device’s age.
Method 4: Decode the Serial Number
Samsung devices have a serial number that also contains manufacturing information. While the serial number might look random, it follows a specific format that encodes the production week and year.
Steps to Decode:
-
Locate your phone’s serial number in Settings → About Phone → Status → Serial Number.
-
The third, fourth, and fifth characters of the serial number often indicate the year and month of manufacture. For example, if the characters are “1A3”, it might indicate that the phone was manufactured in the 1st year of a decade and in March.
Different Samsung models may use slightly different encoding systems, so cross-referencing with an official guide or Samsung support can help you decode it accurately.
Method 5: Use Samsung Members App
Samsung offers an official app called Samsung Members, which provides comprehensive details about your device.
Steps:
-
Download and install Samsung Members from the Google Play Store if it’s not already on your phone.
-
Open the app and navigate to “Phone Information” or “Device Diagnostics”.
-
Look for manufacturing date, warranty status, and other useful details.
This method is particularly useful for refurbished phones, as it ensures that you are getting verified information directly from Samsung.
Additional Tips for Buying Second-Hand Samsung Phones

-
