BCM 50 3.0 number plan conflict

[7upp]

I have a bcm 50 and I'm trying to add 61 as a destination code. I've looked at all dn's and hunt grps and can not find where in the switch I have 61 being used, but the system doesn't allow me to add dest. code 61. I don't know were else to look in the switch to find were its being used. Looking for suggestions.
Thanks in advance

A destination code will interfere with extension numbers, target line received digits, and line pool codes.

Do you have a T1? If so what are the received digits...any starting with 61???

Thanks for the suggestions. I found a Target line that I had setup a few months ago and for got about it.
Thanks again!
