We understand you concern, and there is no need to panic. it's just a typo error in the BLUE DART website, it tend to happens while they are making 1000+ entries in a day.
It will be a problem if pin-code is wrongly mentioned in the site, but in our case only the first letter was mis typed. We are doing absolutely fine.
Adding to it, the package will be delivered today.
Any further clarification kindly revert to us.
