Since Ibanag is spoken in various areas of Northeastern Region of the Philippines (namely within Isabela and Cagayan), there are also minor differences in the way that it is spoken in these areas.
For example, Ibanags from towns in Northern Cagayan, which includes Abulug, Aparri, Camalaniugan, Pamplona and Lallo, tend to replace their "p's" with more "f's".
