Routing Number is a nine-digit numeric code printed on the bottom of checks that is used to facilitate the electronic routing of funds (ACH transfer) from one bank account to another.
Answer Wiki. Gus Fring might have been based on Eugenio Berrios, a biochemist who worked for General Pinochet and was a prominent figure in DINA, the Chilean intelligence agency during the dictator's rule. During his rule, Pinochet supplemented his personal income by producing cocaine and selling it on to Europe and the United States.
Mike Ehrmentraut, Gus Fring's enforcer and de facto underboss, claimed that he was unable to locate any details of Gus Fring's life prior to 1989. If Fring's family was important in Chile or Fring had been part of the Pinochet regime, this seems unlikely.
