How do I check my SanDisk memory card warranty?

A memory card warranty provides assurance that your SanDisk memory card will be free from defects in materials and workmanship for a specified period of time. Having a valid warranty gives you certain rights if your memory card fails prematurely. It’s important to check your memory card’s warranty status so you know if it’s still covered. An active warranty allows you to get a replacement card if yours malfunctions from a manufacturing defect. Knowing the coverage period also helps you understand how long your card is designed to last based on the manufacturer’s estimates. Checking your warranty status is easy and only takes a few minutes.

Locate Your Model Number

The first step in checking the warranty status of your SanDisk memory card is locating the model number. This is a unique identifier that specifies the exact type of memory card you have. The model number is required when using SanDisk’s online warranty checker tool.

You can find the model number printed on the back or bottom of your SanDisk memory card. It may be very small text or in a sticker label. For SD cards, the model number will be 5 or 6 digits, such as “SDSDQXL-064G”. For microSD cards, the model number is on the back of the adapter and will be 8 digits, like “SDSQUNC-064G-AN6IA”.

If you no longer have the physical card, you may be able to find the model number on the receipt or invoice from when you originally purchased it. You can also look it up if you registered your product at the time of purchase.

Knowing the exact model number will ensure you get accurate warranty information from SanDisk when you use the warranty checker. So take a moment to locate it before proceeding.

Find Your Serial Number

The serial number uniquely identifies your SanDisk device and is required to check the warranty status. You can find the serial number printed on the product label or packaging.

For memory cards, the serial number is typically located on the back or side of the card. Look for a long string of letters and numbers etched or printed on the card. The serial number may be next to a barcode.1, 2, 3

For flash drives, the serial number is usually printed on the back or underside of the drive. Look for a sticker with the serial number and other details.

For SSDs, the serial number can be found on the label on the back or underside of the device. It may be next to a barcode or product code.

Make sure to copy the serial number exactly as it appears, including any letters and symbols. Having the correct serial number is crucial for checking the warranty status online or with SanDisk support.

Use the Online Warranty Checker

The easiest way to check your SanDisk warranty status is by using their online warranty checker tool on the SanDisk website. This tool allows you to enter your product’s serial number or model number and instantly retrieve the warranty information.

To use the SanDisk warranty checker:

  1. Go to
  2. Select your product type (such as USB drive, memory card, etc.)
  3. Enter the serial number or model number for your SanDisk product
  4. Click “Check Warranty” to view the warranty status, coverage dates, and other details

The online warranty checker provides an instant way to validate if your SanDisk product is still under warranty. It also allows you to register your product and extend the warranty if desired.

Check Physical Documents

The warranty information for your SanDisk product may be printed on the receipt or packaging you received when originally purchasing the item. Carefully check the receipt and any materials that came in the original packaging, as they often contain details about the warranty coverage and period.

For example, most SanDisk memory cards come with a lifetime limited warranty that warrants the memory card against defects in materials and workmanship according to SanDisk’s warranty policy. This lifetime limited warranty information is typically printed on the packaging or documentation included with the memory card when purchased new.

If you no longer have the original receipt or packaging, you may need to proceed with locating the serial number or model number instead to check the warranty status online or by contacting SanDisk support. But if you still have the original documentation, this can provide you with immediate clarity on the coverage and duration of the warranty for your specific product.

Contact SanDisk Support

If you need help checking or understanding your SanDisk warranty, you can contact SanDisk customer support directly by phone or email. According to Western Digital’s website, SanDisk’s customer service phone number for U.S. customers is 1-866-270-1452. You can call this toll-free number 24/7 and speak to a representative who can look up your warranty status or answer any other questions you may have.

You can also contact SanDisk customer support by email. Fill out the email form on the Western Digital support site and select SanDisk as the product brand. A representative will respond to your email inquiry as soon as possible.

Understand the Warranty Coverage

SanDisk memory cards come with a limited warranty that covers defects in materials and workmanship. The warranty period varies by product, but is typically 1-2 years for SanDisk memory cards according to SanDisk’s warranty page. The warranty starts on the date of purchase.

The SanDisk limited warranty covers issues like the card not being readable or becoming corrupted during normal use. It will provide a replacement card if there is a defect. The warranty also covers failures due to natural causes like an accidental drop or liquid spill.

However, the warranty does not cover normal wear and tear, damage from misuse or improper installation, or issues caused by unauthorized disassembly or modification. The warranty is also voided if the product label or date code has been removed or damaged. Regular maintenance, data recovery, software issues, and any damage caused by the user are not covered.

It’s important to note that the warranty only applies to the memory card itself. It does not cover any data stored on the card, accessories, or indirect damages. Users are responsible for properly backing up their data.

Extend Your Warranty

SanDisk offers options for extending your warranty coverage beyond the default warranty period after purchasing your memory card or storage device. You can extend coverage by upgrading to a premium warranty or purchasing their extended warranty program.

SanDisk’s premium warranty provides up to 5 years of coverage for most products depending on which tier you choose, covering defects in workmanship and replacement in case of failure. You can upgrade to a premium warranty within 90 days of your original purchase date. More details can be found at

SanDisk also offers extended limited warranty plans that allow you to purchase additional years of coverage after your original warranty has expired. You can choose 1-3 years of additional coverage. Extended warranties must be purchased within 90 days once the original warranty has ended. See for more information.

Troubleshooting Tips

If you have issues checking your SanDisk warranty status, here are some tips that may help:

Double check that you have the correct serial number and model number. Referencing the original packaging or documentation that came with your SanDisk product can ensure you have the right details.

Try entering the serial number manually instead of copying and pasting if using the online warranty checker. Sometimes pasting can input incorrect characters.

If the online checker is not working, try again later as the website may be temporarily down. You can also try on a different device incase of any browser issues.

Call SanDisk support if you still cannot get the warranty checker to work. Provide the representative your product details and they can look up and verify the warranty status for you.

As a last resort, register your product for warranty if you have not already done so. This will associate your serial number with your warranty coverage in SanDisk’s system.

If you purchased your SanDisk product from a retailer, you may also contact the retailer for assistance with warranty validation.
