R21 ACH Return Code: Invalid Company Identification

What Causes ACH Return Code R21?

The R21 ACH return code means "Invalid Company Identification" and indicates that the company ID number provided in your ACH transaction doesn't match the receiving bank's records or is formatted incorrectly. This most commonly occurs with Customer Initiated Entry (CIE) transactions where businesses need to provide valid company identification for the receiving bank to process the payment.

Company identification numbers are used by receiving banks to validate the legitimacy of business transactions and ensure proper routing of funds. When the provided company ID is missing, contains typos, is outdated, or simply doesn't exist in the bank's database, the transaction will be returned with an R21 code. This serves as a security measure to prevent unauthorized or fraudulent business transactions.

Can You Retry R21 Payments?

You can retry R21 payments after verifying and correcting the company identification information. Contact the customer to confirm their correct company ID number, check for any typos in your records, and ensure you're using the most current identification information before resubmitting the transaction.
