SafeUM Phone Validation Integration
The 1Lookup SafeUM integration validates phone numbers inside SafeUM. 1Lookup checks each number's line type, carrier, and live reachability and flags spam-reported numbers, then writes the result back so SafeUM only works numbers that can actually connect instead of wasting calls and texts.
Why validate SafeUM data with 1Lookup
In SafeUM, every call and message routed to an invalid or spam-risk number is wasted capacity. 1Lookup checks line type, carrier, portability, and spam reputation so your SafeUM routing is based on how a number really behaves on the network.
Use validated line type and carrier to route SMS versus voice correctly in SafeUM, screen out high-risk and spam-flagged numbers, and prioritise reachable mobile contacts.
What you can do
Phone validation
Confirm a number is real and see its line type (mobile/landline/VoIP) and carrier inside SafeUM.
Live HLR reachability
Run a live HLR check so SafeUM only works mobile numbers that are active and reachable.
Spam & scam screening
Flag spam-reported and high-risk numbers before SafeUM dials or texts them.
Number portability (MNP)
See whether a number has been ported so SafeUM routes to the correct carrier.
How to connect 1Lookup to SafeUM
Create a 1Lookup account and API key
Sign up at app.1lookup.io and start the 7-day free trial, then create an API key on the API Keys page. Test on a few records before rolling out.
Store the key securely
Keep the 1Lookup API key in your backend's secrets store (e.g. environment variables), not in client code.
Call the 1Lookup REST API
From your SafeUM workflow, send the phone number to validate and read the clean JSON response.
Map and persist
Write the validated fields back into SafeUM for reporting and automation.
You can connect SafeUM to 1Lookup without code through Zapier, Make or n8n.
Each one is a native 1Lookup app: search for 1Lookup, paste your API key once, and add a lookup step to any workflow.
Use cases
Smarter call/SMS routing
Route SafeUM traffic by real line type and carrier, sending SMS only to mobile lines and skipping unreachable numbers.
Spam and fraud screening
Flag spam-reported and high-risk numbers before SafeUM dials or texts them.
