P#'s are the numbers that determine placement on 123notary.com. The higher your p#, the higher you show up in search results. The highest p# is 20. An N# is a sequential number that identifies your listing on 123notary.com. More recent n#'s are in the 16000's, but the original n# is 1. We still have many notaries on board from when we first started a decade ago.
If there are more than one notary with the same p# in a given area, the one with the lowest n# gets to be placed a notch higher than the other one. There is often overlap with zip searches, so it pays to have seniority with us.
