Different collectors, not affiliated with one another, have sent bills to me, inside plain envelopes, which only have the mailing date in the upper right corner of envelope, along with the zip code 46068 which is located in Royal Oak, MI. Is there a mass mailing center for bill collectors at this location? The correspondence and return envelopes included, all have the same style, and the only difference, is the contact information for each individual creditor and/or collector. None of which are actually located in Royal Oak, MI. If anyone notices the above in the future, please post. Thanks, Sun
