I received a 1095-B with only the last 4 social security numbers showing, is that acceptable in case of an audit from the IRS?

I am asking because the 2015 1095-B I received last year had all of our social security numbers printed (myself, wife, and child). This year the first 5 numbers are X out and only shows the last 4 of our social security #'s. example XXX-XX-1234. Is this acceptable in case of an audit from the IRS or should I request a new 1095-B form with all of our social security numbers showing.
