New and need some major help!!!!!

Question

I have a field (string 150), called RFID. It has a text coded number for RFID tags. I need to chop off the first part of the number, and leave only 8 identifying number at the back. is there a way of doing this, since I have over 2000 RFID tags, and I do not want to do it by hand.

Example

1st Field RFID_Tag (String, 150) 3000000000000000000000000000000000000000BC201001078 (needs to be reduced into field)
2nd field RFID_Code(String, 50)  BC201001078

They are both in the same table. The RFID_Tag comes from a spread sheet imported into ArcMap, them made into a feature class table, then a Feature class. But how do I remove the excess front numbers

Thank you for all your ideas and help.

No detail window is to be found either.

Did you use the Python parser?

You could just do this in field calculator unless you want to make it a script. Your example has more than 8 characters so modify the number you want if it isn't 8.
RFID_Code =!RFID_Tag![-8:]
