Frequently Asked Questions

What is AsicWarranty.com?

AsicWarranty.com is a bulk ASIC warranty checker that allows you to verify the warranty status of multiple miners serial numbers at once. It supports Bitmain, IceRiver, Elphapex, and Whatsminer devices.

How accurate are the warranty results?

Our results are pulled directly from the official manufacturer APIs, ensuring the highest accuracy possible. We display the exact warranty information as provided by each manufacturer's warranty system.

Is my data secure?

Yes! We don't store any of your serial numbers or warranty data. All information is processed in real-time and immediately discarded. Your serial numbers are only used to query the manufacturer APIs. The only data we store is the total number (count) of serial numbers checked.

Text Input Method (Bitmain Only)

1. Paste your Bitmain serial numbers, one per line
2. Click "Check Warranties" to start processing
3. Wait for all checks to complete (2-second delay between requests)
4. Download results as CSV or view in the table

CSV Upload Method (All Manufacturers)

1. Download the CSV template or create your own
2. First column: Serial Number, Second column: Manufacturer
3. Upload your CSV file
4. Results will process automatically with rate limiting
5. Download the completed results

CSV Format Example

Why is there a 2-second delay between requests?

We implement rate limiting to respect the manufacturer APIs and prevent being blocked. This ensures reliable service for all users and maintains access to warranty data.

How many serial numbers can I check at once?

There's no strict limit, but we recommend batches of 50-100 serial numbers for optimal performance. Larger batches will take longer due to the rate limiting, but will complete successfully.

What happens if a request fails?

Failed requests are marked as "Error" in the results. Common causes include invalid serial numbers, network issues, or temporary API unavailability. You can retry failed checks.

"Serial number not found" error

This usually means the serial number is invalid, doesn't exist in the manufacturer's database, or has never been registered. Double-check the serial number format and try again.

"Network Error" or timeout

This indicates a temporary issue with the manufacturer's API or your internet connection. Wait a few minutes and try again. The system will automatically retry failed requests.

CSV upload not working

Ensure your CSV has the correct format: Serial Number in column A, Manufacturer in column B. Download our template to see the exact format required.

Warranty shows 0 days but status is "success"

This means the serial number was found and is valid, but the warranty has expired. The "success" status indicates the API call was successful, not that warranty is active.
