Personator Update – Reverse Melissa Address Key (MAK) Lookup

The Melissa Address Key, or more commonly referred to as MAK, is Melissa’s proprietary unique identifier for every unique mailing address in the US. This unique MAK identifier allows for easily indexing address records in your database without the concern of its value possibly changing due to its persistent nature. This is unlike how other primary key values are generated which can change as addresses change over time.

Our Personator API now not only has the ability to produce MAK values given an address, but also vice versa. Given a unique MAK number, Personator can easily do a reverse lookup to provide the address tied to that persistent MAK. This latest update re-works Personator’s Reverse MAK Lookup implementation, so that the information returned is always the latest and most accurate.
