ELT 406 MHz Registration question

[LB 408A]

I'm filling out the form for NOAA and it is asking for a checksum number. The AKC E-04 has two labels stuck on it and each label has a different serial number one label has a unique 15 digit hex code on it the other does not. It is new and factory programmed for USA, my supplier didn't know the answer when I called.

it is asking for a checksum number.

That is not a required field as not all ELT mfg'r provide a checksum value. Here's a couple references:

Just looked at the past 2 registration forms for my ACK E04. No entries in the Checksum field.

Thanks for your replies since the website says it's not required I'm going to register without checksum and wait and see what happen if anything.
