What is a Checkbook

A checkbook is a folder or small book containing preprinted paper instruments issued to checking account holders and used to pay for goods or services. A checkbook contains sequentially numbered checks that account holders can use as a bill of exchange. The checks are usually preprinted with the account holder's name, address and other identifying information. In addition, each check will also include the bank's routing number, the account number and the check number.


A checkbook is comprised of a series of checks that can be used to make purchases, pay bills, etc. With the advent of online commerce and banking, more people are making purchases and paying bills online, thereby reducing or eliminating the need for paper checkbooks. Checkbooks include a set quantity of numbered checks, and, in addition, usually contain some type of register in which users can keep track of check details and balance account statements.

Checkbook Example

For example, Bob went to his local bank and opened a checking account. He made a starting deposit into the account of $3,000. Bob was issued a checkbook with 100 checks which he can use to pay funds from the account to providers of goods and services. After Bob fills out the check with the payee's information, the payee must then deposit the check into their own bank account. The receiving bank will contact Bob's bank to verify funds are available and clear the check.
