Barcode scanner reads the wrong value using USPS OneCode

Aspose.BarCode Product Family

Hi,

I’m using Aspose.Barcode version 23.1.0, we generated a barcode for the following value
0027090323734116180477077361580

However when a barcode scanner try to read that, it reads this value
8491090323734116180477077361566

Here the code fragment we use to generate the barcodes:

private Stream GetFirstClassBarcodeStream(string barcodeValue)
{
    MemoryStream bcStream = new MemoryStream();

    if (!string.IsNullOrEmpty(barcodeValue))
    {
        using (BarcodeGenerator bcGen = new BarcodeGenerator(EncodeTypes.OneCode, barcodeValue))
        {
            bcGen.Parameters.Barcode.CodeTextParameters.Location = CodeLocation.None;
            bcGen.Save(bcStream, BarCodeImageFormat.Bmp);
        }
    }

    return bcStream;
}

Attached you can find the generated barcode as well as a photo of the printed envelope.

Is there any setting we are missing to generate the barcodes? Could you provide a solution for this?

Thanks.

@jquijivix,

Thanks for the barcode images and details.

After initial testing, I am able to reproduce the issue as you mentioned by using the following sample code. I found Barcode reader/scanner reads the wrong value using USPS OneCode type.

BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.OneCode, "0027090323734116180477077361580");
gen.Parameters.Barcode.CodeTextParameters.Location = CodeLocation.None;
 using (Bitmap bmp = gen.GenerateBarCodeImage())
     bmp.Save("e:\\test2\\StoreImageAsBitmap.bmp",ImageFormat.Bmp);

using (BarCodeReader reader = new BarCodeReader("e:\\test2\\StoreImageAsBitmap.bmp", DecodeType.OneCode))
{     
     foreach (BarCodeResult result in reader.ReadBarCodes())
     {
         Console.WriteLine(result.CodeType);
         Console.WriteLine(result.CodeText);
     }
}

Console output:

OneCode
8491090323734116180477077361566
