Synovus positive pay file format
There is no single fixed layout. You define your own file map in Synovus Gateway.
Independent documentation. Not affiliated with or endorsed by Synovus.
Build a matching file with the free generator: pick a generic layout or use the custom builder, then map it once in Synovus Gateway. Your check data never leaves your computer.
How Synovus check issue files work
- File mapping requirements live in the Appendix of the Positive Pay User Guide, which is available inside Synovus Gateway (behind login).
- You define a file map for your own layout, then upload issue files against it.
- With Payee Positive Pay, the payee name in the file must match the printed check exactly.
Required data: account number, check number, amount, issue date, and payee name when Payee Positive Pay is enabled.

How to create a Synovus positive pay file
Because Synovus reads whatever layout you register in its portal, the simplest approach is a clean CSV. In the generator, choose the generic CSV layout (or build your own in the custom builder), create the file from your check register, then define the matching file map in Synovus Gateway once. After that, every check run is the same two steps: generate the file, upload it. Always verify your first file with a test upload.
