This page provides some random Illinois(United States) telephone numbers and mobile(cellular) phone numbers.

We can generate these telephone numbers because according to the North American Numbering Plan, Illinois has some fixed area codes such as 773537, therefore, we only need some numbers together into a legitimate phone number.

All these generated Illinois phone numbers seem to be true, because they have a completely legal format and conform to the North American Numbering Plan, but these phone numbers absolutely fake, we just generate these phone numbers according to the area code, so please don't try to dial them, perhaps the number is true, but believe me, this is a very low probability event, we are sorry about such a thing and trying our best to avoid that; at the same time, some phone numbers don’t exist for now but we couldn’t predict that whether these numbers are assigned to some company or family in the future.

We couldn’t make sure that all the information we offer are totally correct and complete because of American number rules in constantly update, but we will update as soon as possible, if you have any questions, please don't hesitate to contact us, if you want to learn more rules of US telephone number, please refer to Wikipedia - North American Numbering Plan.
