Post Tracking number checksum

New Topic

Hello all!

I am working on an open source software project to track packages, including China Post.

One of the things I'd like to do is confirm whether a number is a valid China Post number.

I understand the format, which is 2 alpha, 9 digits, 2 alpha.

Is there any kind of checksum or rule I can use to confirm validity of the number?

Thanks,
-Dan

put your number here http://track-chinapost.com/startairmail.php , if it can show any result other than "parcel has not been received by china post", then it should be valid number.
