Which ESN #?
 

Guys....
I am filling out the rebate from for the PPC-6700 for UTSTARCOM....
It is asking me for the ESN #.... there are 2 ESN #s...
1. ESN HEX...
2. ESN DEC...
which one do I put?

The field will take 11 digits, which is exactly the number of digits in the ESN DEC (HEX is 8 digits long), so it looks like they want the DEC.

Technically you should be able to give them either one since it's the same number just expressed in two different bases.
