Section 240-B. Order of support by parent

When the court makes an order of
  support pursuant to section two hundred forty of this article, and where
  permitted under federal law and where  the  record  of  the  proceedings
  contains  such  information, the court shall require the social security
  number of such parent to be affixed to such  order;  provided,  however,
  that  no  such  order  shall  be invalid because of the omission of such
  number. Where the record of the proceedings contains  such  information,
  such  order  shall  also include on its face the name and address of the
  employer, if any,  of  the  person  chargeable  with  support  provided,
  however,  that  failure  to  comply  with  this  requirement  shall  not
  invalidate such order. Where the order  of  child  support  or  combined
  child  and  spouse  support  is  made on behalf of persons in receipt of
  public assistance or in receipt of  services  pursuant  to  section  one
  hundred  eleven-g  of  the  social services law, the court shall require
  each party to  provide,  and  update  upon  any  change,  the  following
  information  to  the  court  by  reporting  such  change  to the support
  collection unit designated by the appropriate social services  district:
  social  security  number,  residential  and mailing addresses, telephone
  number, driver's license number; and name, address and telephone  number
  of  the  parties'  employers.    Due process requirements for notice and
  service of process for subsequent hearings are met, with respect to such
  party, upon sending written notice by  first  class  mail  to  the  most
  recent  residential  address on record with the support collection unit;
  or by sending by first class mail written  notice  to  the  most  recent
  employer  address  on record with the support collection unit, if a true
  copy thereof also is sent  by  first  class  mail  to  the  most  recent
  residential address on record with the support collection unit. Any such
  order  issued  on  or  after  the first day of October, nineteen hundred
  ninety-nine shall also include, where  available,  the  social  security
  number of each child on whose behalf support has been ordered.
