Uniqueness of EFT Payment File number with regards to other file numbers generated in AP & AR module

We have implemented both Payables and Receivables modules from Oracle for our client. Currently implementing the PAD process of acknowledgement, need to understand if the AP Payments File Number and AR O2C Settlement batch number will ever overlap ? Also further in case of AP modules, will the EFT Payment File Number ever overlap or be same as the Positive Pay File number generated. This is because we are currently receiving all AP and AR PAIN files in a single location from the Bank. There is a requirement to distinctly identify each file.
