help with query

I need to do a join on two fields but only part of the data in the fields.
the field is 18 digits long but I need the join to be dependent on only the first ten digits.

I need them to match by the first ten digits so the two above referenced accounts would result in a match

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
