In India, millions of people buy new or used smartphones every year. Knowing your phone’s manufacturing date (also called production date) is very useful. It helps you:
- Check warranty validity (most brands give 1-year warranty from manufacturing or purchase).
- Verify if a used phone is genuinely new or too old.
- Avoid refurbished or fake phones when buying second-hand on OLX, Cashify, or local shops.
- Understand device age for resale value or software update support.
- Check quality — older stock might have battery or hardware issues.
Whether you’re buying a used phone, checking warranty details, or verifying device age, this guide shows how to find your phone’s manufacturing date quickly and accurately.
1. Check the Original Box (Easiest Method)
The phone’s packaging often has the manufacturing date printed on it.
- Flip the box and look for a white sticker with barcodes.
- You’ll usually see a date like “MFD: MM/YYYY” or “Manufactured: Week 45, 2025”.
- Also check the serial number on the box.
Tip: Always keep the original box, especially for warranty claims at service centers in India.
2. Check in Phone Settings (No Dialing Needed)
On Android Phones
- Open Settings (gear icon).
- Scroll to About phone (or About device).
- Tap Status or All specs.
- Look for Manufacturing date, Build date, or similar info.
Some brands show it directly; others show only the build number (which contains date clues).
On iPhone (iOS)
- Go to Settings > General > About.
- Note the Serial Number.
- For newer iPhones (iOS 17+), check Settings > Battery > Battery Health & Charging — some models show manufacturing date directly.
3. Use Secret USSD/Dialer Codes (Fastest for Android)
These hidden codes work on many Android phones:
- Common Code: Dial *#*#4636#*#* (This opens Testing menu → Phone information).
- Samsung: Dial *#12580*369# → Look for RF Cal or manufacturing date (often shown in reverse like YYMMDD).
- Many Android phones: Dial *#197328640# or *#*#197328640#*#* → Go to Menu Version Information > Hardware Versions > Read Manufacturing Date.
- Some models: Dial *#0000# for version and manufacturing info.
Note: Codes may not work on all phones or after certain updates. Try them one by one.
4. Check Using IMEI or Serial Number
Find IMEI/Serial Number
- Dial *#06# — IMEI and sometimes Serial Number appear instantly.
- Or go to Settings > About phone > Status.
Decode or Check Online
- Samsung: The serial number contains manufacturing info (e.g., 4th-5th characters often indicate year/week).
- iPhone: Use the serial number on Apple’s official coverage checker (support.apple.com) or sites like chipmunk.nl to decode the date.
- Other brands: Visit trusted sites like imei.info or imei24.com. Enter IMEI and check for production date or warranty info.
Warning: Use only trusted websites. Avoid suspicious sites that ask for too much information.
5. Brand-Specific Easy Methods (Popular in India)
- Samsung Galaxy: Use the *#12580*369# code or check serial number on Samsung Members app.
- Xiaomi / Redmi / Poco: Settings > About phone > All specs. Sometimes use service menu codes.
- OnePlus / Realme / Oppo / Vivo: Check box or use IMEI on brand’s official website.
- Google Pixel: Settings > About phone > Device identifiers.
- iPhone: Serial number decoding is most reliable.
6. Other Helpful Ways
- Apps: Search Play Store for “Phone Info” or “Device Info” apps. They often show manufacturing details (choose highly-rated apps only).
- Service Center: Take your phone to an authorized center — they can check exact manufacturing date.
- Router or Connected Devices: Not reliable for manufacturing date.
Important Tips for Users
- When Buying Used Phones: Always check manufacturing date + IMEI for blacklist status (use ceir.gov.in in India).
- Warranty: In India, warranty usually starts from the date of purchase, but manufacturing date helps verify age.
- Battery Health: Older phones (more than 2-3 years) may have degraded batteries. Check in settings.
- Software Updates: Brands stop updates after 3-7 years from manufacturing.
- Refurbished Check: If manufacturing date is much older than purchase date, be careful.
- Dual SIM Phones: Manufacturing date is for the device, not per SIM.
- After Factory Reset: The date remains the same as it’s hardware-based.
Common Problems & Solutions
- No date in settings? Try dialer codes or IMEI check.
- Code not working? Your phone model may not support it. Use settings or box method.
- Buying online? Ask seller for clear photos of box, IMEI, and serial number.
- iPhone not showing? Use Apple’s official serial number checker.
- Still confused? Search Google with your exact model, e.g., “Redmi Note 13 manufacturing date check”.
