In which record do you find the Block Count?

The Block Count is found in the File Control Record. This record plays a key role in summarizing the contents of the ACH file, including critical elements like the total number of blocks and records within the file. The File Control Record acts as a verification mechanism, ensuring that the total block count matches the sum of blocks contained in all the batches and entry detail segments of the file. This is essential for maintaining the integrity and accuracy of the data transmitted in ACH processing.

The other records, such as the File Header Record, Batch Header Record, and Entry Detail Record, serve different purposes within the ACH format. The File Header Record introduces the file and includes metadata such as the originator's information. The Batch Header Record contains details about the batch, like its identification and type, while the Entry Detail Record pertains to individual transactions. However, none of these records encapsulate the overall summary metrics like the Block Count that are specifically included in the File Control Record.
