consideration   for   CMFs   are   Pensacola,   Florida;   and Puget   Sound,   Washington. REDUCING  POSTAGE  COSTS Activities   not   served   through   a   CMF   can   reduce postage   costs   through   proper   mail   piece   preparation, class/service   selection,   and   selecting   the   appropriate medium  by  which  information  is  transmitted. Do   not   use   U.S.   Government   messenger   (guard mail)   envelopes   for   the   consolidation   of   USPS mailings. When   less   expensive,   communicate   by   e-mail, Defense   Switched   Network   (DSN)   Telephone,   or FAX. Update    mailing    lists    regularly.    Incorrect    or incomplete   addresses   cause   mail   to   be   delayed   or returned   and   wastes   postage.   Incorrect   or   incomplete addresses   require   rework   to   properly   prepare   the article   for   re-mailing.   In   addition,   it   reduces   the amount   of   mail   subjected   to   Second   Destination Transportation   (SDT)   charges. Use   guard   mail   courier   service   for   delivery   to military   activities   or   executive   board   agencies,   (VA, GSA,  IRS,  etc.)  within  the  same  area  to  avoid  postage. Consolidate   individual   pieces   of   correspondence addressed  to  the  same  location  in  one  envelope.  If unable   to   consolidate   the   pieces,   use   the   smallest possible   envelope.   USPS   assesses   a   surcharge   on envelopes  weighing  one  ounce  or  less  when  the  length exceeds  11  1/2  inches,  the  height  exceeds  6  1/8  inches, or  the  thickness  exceeds  1/4  of  an  inch. Reduce   mailing   weights   by   printing   on   both   sides of   the   paper,   selecting   the   lightest   weight   paper,   using the   smallest   envelope   or   package,   and   promoting computer   output   formats   that   allow   the   maximum   use of   available   print   space. Ensure   all   items   mailed   pertain   exclusively   to   U.S. Government   business   and   contain   no   personal   matter. Limit   the   use   of   expensive   special   services (registered,   certified,   and   insured)   except   when required. To  meet  the  Required  Delivery  Date  (RDD),  use  a less   costly   class   of   mail.   As   a   general   rule,   Standard Mail   (A)   or   Standard   Mail   (B)   weighing   over   one pound   is   less   expensive   than   First-Class   or   priority mail.   Consider   a   carrier   other   than   USPS   to   ship   at lower   rates   if   security   requirements   are   met.   Before using  commercial  carriers,  ensure  items  being  mailed are  not  required  to  be  sent  by  USPS. Use   presorted   First-Class   and   Standard   Mail   (A) bulk   rates   when   the   mail   qualifies.   First-Class mailings  that  contain  500  or  more  pieces  and  Standard Mail  (A)  mailings  that  contain  200  pieces  or  more  can qualify   for   a   less   expensive   presorted   rate.   Details about   other   discount   rates   can   be   obtained   from   your local  CMF  or  USPS  account  representative. Do   not   affix   postage   to   courtesy   reply   return   mail that   is   normally   used   when   mailing   RSVPs   for retirements,   change   of   commands,   commissioning, and  so  forth.  Allow  the  addressee  to  affix  the  required postage. Obtain   priority   and   Express   Mail   envelopes, mailing  containers,  and  labels  from  the  USPS.  These i t e m s    a r e    f r e e    a n d    c l e a r l y    i d e n t i f y    m a i l i ng classifications. Type   or   print   addresses   by   mechanical   means   in uppercase   letters   without   punctuation,   except   for   the hyphen   in   the   ZIP+4   Code.   Include   the   street   address or   post   office   box   number   on   the   delivery   line   of   the address.   Mail   that   is   addressed   properly   can   be   sorted by  machine  and  barcoded.  If  your  mail  is  processed  by automated   equipment   through   a   CMF   or   other   mail center,   your   command   can   share   in   discounts   offered by   the   U.S.   Postal   Service. Q5.  Envelopes  larger  than  11  1/2  inches  and  6  1/8 inches  wide,  or  1/4  of  an  inch  thick  are  assessed a  surcharge  if  the  weight  is  less  than  how  many ounces? SECURITY   OF   POSTAGE   STAMPS To   prevent   unauthorized   use,   in   addition   to   the security   measures   listed   in   OPNAVINST   5218.7, enclosure   (1),   chapter   5,   Paragraph   B3,   the   OMM   will ensure: Records   reflecting   the   number   and   cost   of commercial   postage   stamps,   stamped   envelopes, and  stamped  cards  procured,  used,  and  on  hand are   maintained.   Figure   1-1   shows   the   Daily Record   of   Stamps,   Stamped   Paper,   and Nonpostal  Stamps  on  Hand,  PS  Form  3295. A   locally   generated   daily   stamp   sales   worksheet is  shown  in  figure  1-2. A   monthly   audit   of   the   official   stamp   stock   is conducted   and   recorded   on   an   audit   form   (fig. 1-3) . 1-4
