How to create this USPS code128 bar code?

Postby JohnM on Fri Mar 30, 2012 2:39 pm

I bought your US Postal Font Package to create code128 barcode for confirmation service. I am stuck with getting the barcode like the one attached. Your USPS_EAN128 function gives a barcode with 20 digits encoded (scanned to 22 digits). The sample barcode scanned as 30 digits.

Despite that the human readable text displays 22 digits, this is a concatenated UCC/EAN128 barcode which encodes 30 digits.

The data is expressed as (420)00763(91)84969010386135792661, which are two EAN128 combined.


You can use EAN128Ex function to get barcode string, and format with "MRV Post128" font. See KB10049 for details.
