Notes: Huntington maps your file once in Business Online, so field order is up to you. This matches the sample layout in their guide. Create your Issue File Map with these fields in this order (comma separated, date MMDDYY, amount format $$$$$$$.CC). Issue types: IS = issue, CN = void. Check numbers max 10 digits; payee max 80 characters and must match the check exactly; no trailer or total rows. Files upload hourly 6 a.m.–8 p.m. ET.
