Melissa Is an Enterprise Data-Quality Suite. Veriastra Is an API You Can Start Today.
Melissa focuses on address verification and broad data quality for large organisations. Veriastra is a narrower, developer-first API for phone, email, IP and domain validation with self-serve pricing.
Start in minutes
Self-serve signup, a card-required trial and documented endpoints instead of a procurement cycle.
Priced in the open
Every product's credit cost is on the pricing page, including the bought-per-call add-ons we mark up front.
Focused scope
We do not do postal address verification. What we do cover runs on engines we operate ourselves.
Where Melissa is the better buy
Every product has a job it is built for. These are the jobs where Melissa is the answer and we are not, said plainly so you can tell in two minutes whether the rest of this page applies to you.
Postal address data at a depth we do not carry
Address verification, standardisation and the postal certifications that go with it are decades of their work. We do not verify or standardise a mailing address and are not going to.
Identity and demographic datasets
They license consumer identity data we have chosen not to buy or resell. If your requirement is identity verification against a licensed consumer file, that is theirs.
Global address coverage
Their country coverage on postal data is far wider than anything we hold.
