Stripe Phone, Email & IP Validation Integration
Validate phone, email, and IP data automatically across Stripe, so your team works from clean, verified records.
The 1Lookup Stripe integration validates phone, email, and IP data for Stripe. 1Lookup checks phone line type and carrier, email deliverability, and IP risk (VPN, proxy, and fraud signals), then returns structured results so Stripe acts on verified, lower-risk data instead of guesswork.
Why validate Stripe data with 1Lookup
Checkout is where Stripe is most exposed to fraud and typo'd contact details. 1Lookup verifies the phone, email, and IP behind each order, including VPN/proxy and fraud signals, so you can flag risk and keep delivery and follow-up reachable.
Combine phone, email, and IP validation in Stripe to score order risk and suppress undeliverable contacts, so the post-purchase SMS and email you send through your own tools reach real customers.

Frequently asked questions
What does 1Lookup validate for Stripe?
1Lookup validates phone (validity, line type, carrier), email (deliverability, disposable/role-based), and IP (geolocation, VPN/proxy, risk) data. You choose which fields to store in Stripe.
Do I need to write code to use 1Lookup with Stripe?
Yes, this integration calls the 1Lookup REST API, so it suits developer workflows. You authenticate with an API key and map the JSON response into Stripe.
Can I validate records I already have in Stripe?
Yes. Alongside real-time validation, you can run existing Stripe records through 1Lookup batch validation and write the cleaned results back.
How long does setup take?
Setup is quick for most teams. The exact time depends on how many fields you map and whether you validate in real time, in bulk, or both.
