but cannot be lower than the verified account code length. The verified account code
length defines the number of digits that the system will verify before it accepts an
account code as valid. As well, verified account code length defines the number of valid
account codes that a programmer can store (as shown in the following table). A
programmer should be aware that when he or she changes the verified account code
length, the system automatically empties the list of valid account codes.

Even though a programmer has arranged a system to force users to enter account codes
before making calls, they can always dial certain programmer-defined emergency
numbers without an accompanying account code entry. The system allows a maximum of
10 programmable emergency numbers. The minimum length of an emergency number is
1 digit and the maximum length is 12 digits. Users may dial emergency numbers
manually, through system speed dial, personal speed dial, last-number redial, or
automatic redial—with or without account code entry.
