Substitute Checks and Your Rights - Check 21 FAQs

Find the answers to all your questions about Check 21.




  • ​​​Check 21 is a federal law that was designed to improve the efficiency of the nation's check processing system by decreasing processing time and transportation costs. Check 21 accomplished this by allowing original paper checks to be removed from the check collection process, processed in electronic form, and later replaced with a new kind of paper document called a "substitute check." Check 21 provides that "substitute checks" are the legal equivalent of the original check.  

  • These checks are similar in size to original checks, with a slightly reduced front and back image. The front of a substitute check states: "This is a legal copy of your check. You can use it the same way you would use the original check." A substitute check that meets these requirements is generally subject to similar federal and state laws that apply to an original check.

  • ​Check 21 contains a special procedure that allow consumers to file a claim and obtain a refund of certain losses related to a substitute check. These provisions apply only to consumers. However, all customers have the right to pursue the correction of errors under other provisions of Check 21 – as well as under existing law.

  • ​​Federal law provides a special procedure that all a consumer to request a refund for losses you suffer if a substitute check is posted to your account. For example, if you think we withdrew the wrong amount from the account or we withdrew money from the account more than once for the same check. The losses that are attempted to be recovered under this procedure may include the amount that was withdrawn from the account and fees that were charged as a result of the withdrawal:​

    • The amount of your refund under this procedure if limited to the amount of your loss or the amount of the substitute check, whichever is less
    • Up to $2,500 (plus interest if the account is interest bearing) of a refund may be received within 10 business days after we receive a claim and the remainder of the refund not later than 45 calendar day after we receive a claim
    • We may reverse a refund if we later are able to demonstrate that the substitute check was correctly posted to the account
  • Federal law limits a refund to the amount of the consumer's loss, up to the amount of the substitute check plus interest if the account earns any. Consumers could be entitled to additional amounts under other state or federal law.
