2nd class mail 0216 eadc 0370 c9c0
A cryptic message!
After some analysis, I think I have a possible solution:
2nd class mail
is likely a reference to the type of postal service used to send the message.
0216
could be a date code, possibly indicating the date the message was sent (February 16th).
eadc
might be a coded message or a checksum.
0370
could be a postal code or a routing code.
c9c0
is likely a checksum or a verification code.
Putting it all together, I'm going to take a wild guess:
This message might be a postal tracking number or a confirmation code for a package sent via 2nd class mail on February 16th. The eadc
and c9c0
parts could be error-checking codes to ensure the message was transmitted correctly.
Am I correct?
