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 reassures Gus that if he can't find out anything about him from before 1989 (the year Fring emigrated to Mexico, and subsequently the United States), then it is unlikely that the DEA will either. In the late 80's, Gus and his partner, Max Arciniega, started a chain of Los Pollos Hermanos restaurants in Mexico. This, however, was a cover for their true intentions: to manufacture methamphetamine.
