Melissa Data Lookups runs its Lookups API on a cloud backbone that spans three AWS availability zones across the United States, delivering geographic redundancy and automatic fail‑over. Internal logs for Q4 2023 show an average uptime of 99.92 %, with occasional maintenance windows causing brief pauses. The service draws from more than 150 million verified address records, 85 million name‑phone‑email combinations, and a continually refreshed postal‑code database sourced from national postal services. Each response is filtered through automated validation rules and manual quality checks, though Melissa does not guarantee error‑free data and disclaims liability for downstream use.
Melissa Data Lookups also powers a verification platform that ingests legacy datasets, real‑time commerce feeds, and public records to deliver a unified view of contact information for 34 supported countries. The engine processes more than 30 billion address lookups each year and cross‑references 12 million nightly‑updated phone‑number reputation scores. Clients such as a national retailer and a major insurance carrier report mail‑return reductions of up to 18 % and identity‑risk flags generated in under two seconds per request. The Personator engine enriches a name with gender, age range, and fraud likelihood, while the mobile app—downloaded over 420 000 times and rated 4.7 stars—offers offline ZIP‑code maps, real‑time property‑tax estimates, and one‑tap email verification that checks MX records and SMTP responses.

Melissa operates the Lookups API on a cloud infrastructure that spans three AWS availability zones in the United States, providing geographic redundancy and automatic fail‑over. In the fourth quarter of 2023 the service recorded an average uptime of 99.92 % according to internal logs, though occasional maintenance windows may cause brief interruptions. The API draws from more than 150 million verified address records, 85 million name‑phone‑email combinations, and a continually refreshed postal code database sourced from national postal services. While the company applies automated validation rules and manual quality checks to each response, it does not guarantee that any single data element is error‑free, and it disclaims liability for downstream use of the information.

Search Lookups | Melissa Lookups
The Search Lookups endpoint extends the core API by allowing Boolean operators, wildcard queries, and pagination up to 10,000 results per call. In Q3 2024 the endpoint handled 12 million distinct search sessions, with an average latency of 215 ms measured from a West Coast data center. The service leverages a proprietary phonetic matching algorithm that returns relevant results even when input contains typographical errors, a feature that helped a logistics firm decrease address correction time from 4 minutes to 12 seconds per shipment. All returned records include a confidence score calculated from source reliability, timestamp freshness, and historical match success rate.

Salesforce Lightning Lookups – Melissa Wiki
To add a Melissa Lightning Lookup field in Salesforce, administrators navigate to Setup → Object Manager, select the target object (for example, Contact), and click Fields & Relationships → New. The field type chosen is “Lookup (Lightning)” and the external service is identified from the drop‑down menu; selecting “Clean Suite Personator Result” directs Salesforce to call Melissa’s Personator API with the Contact’s email address. After mapping the API response fields to custom Salesforce fields (such as PersonatorGender and PersonatorRiskScore), the wizard prompts a field‑level security review, ensuring that only profiles with “Read” permission can view the enriched data. Once deployed, the lookup refreshes asynchronously every 24 hours to keep the enriched attributes current.

Property V4 LookupProperty – Melissa Wiki
The Property V4 service introduces the Melissa Address Key (MAK), a ten‑digit alphanumeric code that uniquely identifies a single dwelling unit across the United States. MAK replaces the legacy AddressKey and is generated by concatenating the base ZIP + four‑digit delivery point with a checksum derived from the street‑name hash. For multi‑unit complexes, the BaseMAK represents the shared address (for example, 123 Main St Apt 0) while each individual unit receives its own MAK suffix (e.g., 123 Main St Apt 5 → MAK = 1234567890). API responses are delivered in JSON format, for example: {“MAK”:”1234567890″,”BaseMAK”:”1234500000″,”Latitude”:38.8977,”Longitude”:-77.0365}. The service also returns construction year, occupancy status, and parcel ID when queried against county assessor datasets.

Melissa Data Phone Number Lookup – August 2022
The August 2022 release of Melissa Data Phone Number Lookup added support for over 250 carrier prefixes in North America and integrated a new carrier‑ownership database sourced from the Federal Communications Commission. Each lookup now returns the carrier name, line type (mobile, landline, VoIP), and a risk indicator based on historical spam complaints, enabling call‑center supervisors to flag high‑risk inbound calls in real time. The service also provides international dialing‑code validation for more than 100 countries, pulling data from the International Telecommunication Union’s numbering plan repository. Clients reported a 22 % reduction in fraudulent call‑back incidents after implementing the API within their IVR systems.

MelissaData Phone Lookup – August 2022
The August 2022 MelissaData Phone Lookup update introduced batch processing that can handle up to 50 000 numbers per request, returning a CSV file with columns for phone number, carrier, line type, and fraud score. The fraud score is calculated from a machine‑learning model that weighs factors such as call‑frequency spikes, user‑reported spam tags, and SIM‑swap activity, achieving a 93 % precision rate in internal testing. The API also includes a reverse‑lookup feature that returns the registered owner’s name when publicly available, drawing from state‑issued telecom licensing records. Early adopters in the e‑commerce sector used the service to verify order‑time contact numbers, decreasing order‑cancel rates by 7 %.
