Pre-Authorized Transactions

Pre-Authorized Deposits

Setting up automatic deposits is easy. Identifying the proper identification number is important so that these transactions process accurately and timely.

There are three identification numbers within the encoding on a cheque that are required to set up a pre-authorized transaction:
