Quick answer: The fastest way to find out how old your phone is — check the manufacturing date on the original retail box, look in your phone’s Settings under About Phone (or General > About on iPhone), or decode the serial number with your manufacturer’s coverage-check tool. Most people get their answer in under two minutes with one of these methods.
Why does it matter? Your phone’s age determines whether it still gets security updates, how much it’s worth as a trade-in, and whether that dying battery is normal wear or a defect. Here’s every reliable way to find your phone’s age, for both iPhone and Android.
Method 1: Check the Retail Box (Fastest)
If you still have the original box, flip it over and look for the white sticker with barcodes. Most manufacturers print the manufacturing date right on that label, often alongside the serial number and IMEI. This is the most direct answer you’ll get — no decoding required.
No box? The next methods take only slightly longer.
Method 2: Look in Your Phone’s Settings
On iPhone
- Open Settings, then tap General.
- Tap About.
- Note your serial number and model number.
Apple encodes manufacturing info in the serial number. Enter it on Apple’s Check Coverage page (check your service and support coverage) to see the original purchase date and warranty status — which tells you almost exactly how old the device is. As Reolink’s phone-age guide notes, this official lookup is the most reliable route for iPhones.
On Android
- Open Settings, then tap About Phone (sometimes under System first).
- Look for manufacturing date, hardware version, or status entries.
- Some brands (notably Samsung) show the manufacturing date directly here.
Android menus vary by manufacturer — if you don’t see it immediately, check sub-menus like “Version Information” or “Hardware Versions.” The exact location differs between Samsung, Google Pixel, Motorola, and others.
Method 3: Decode the Serial Number
Many manufacturers encode the production date inside the serial number itself. For iPhones, the fourth character of older serial formats indicates the manufacturing year, and other digits encode the production week — though Apple has changed formats over the years, so decoding by hand is unreliable for newer devices.
The practical approach: use a serial-number lookup tool. Your manufacturer’s official coverage checker is the safest option. Third-party decoder sites exist too, but be cautious — as Reolink warns, shady sites that ask for your IMEI may be harvesting personal data. Stick to official tools whenever possible.
Method 4: Dial *#06# for Your IMEI
Open your phone dialer and type *#06#. Your IMEI (International Mobile Equipment Identity) number appears instantly. The IMEI itself doesn’t directly show the age, but it’s the unique identifier that lookup tools use to pull manufacturing records. Never share your IMEI publicly or paste it into random websites.
Method 5: Check the Model’s Release Date
Sometimes “how old is my phone” really means “how old is this model.” Search your exact model name plus “release date.” If you own a phone released in 2021, the device itself can’t be older than that — and if it’s a used purchase, the manufacturing date methods above will narrow it down further.
Knowing your phone’s age also helps you figure out what it’s still worth.

How Long Do Phones Last?
For context, here are typical support lifespans by brand:
- iPhone: 4–8 years of iOS updates and security patches
- Samsung (flagship): 3–6 years
- Google Pixel: 3–5+ years (newer models promise longer)
- Budget Android brands: 2–4 years
Your phone’s “expiration” is really about software support, not hardware failure. Once security updates stop, the device becomes increasingly risky for banking, email, and anything sensitive — even if it still works fine otherwise. Sites like endoflife.date track exactly when manufacturers drop support for specific models, which is worth checking before buying any used phone.
Phone Age FAQs
Can I tell my phone’s age from the serial number alone?
Sometimes. Many manufacturers encode production dates in serial numbers, but the formats differ and change over time. The reliable move is entering the serial number into the manufacturer’s official coverage-check tool rather than decoding it by hand.
Does the manufacturing date differ from the purchase date?
Yes — your phone was built before you bought it, sometimes months earlier. For warranty and support purposes, the purchase date usually matters more; for hardware age (like battery wear), the manufacturing date is the truer number.
Is it safe to enter my IMEI on a lookup website?
Stick to official manufacturer tools. Random third-party IMEI checkers can be data-harvesting operations, and your IMEI is sensitive enough that you shouldn’t broadcast it.
My phone is past its support end date. Should I replace it?
If you use it for anything sensitive — banking, work email, two-factor authentication — yes, it’s time. Without security patches, known vulnerabilities stay open forever. As a secondary device for music or alarms, it’s fine to keep around.
The Bottom Line
To find out how old your phone is, check the retail box first, then your Settings (General > About on iPhone, About Phone on Android), then run the serial number through your manufacturer’s coverage checker. The whole process takes minutes, and knowing your phone’s true age helps you decide whether to keep it, trade it in, or retire it before the security updates run out.
