Instantly Validate Email Adresses & Phone Numbers
Boost the quality of your contact information by validating email addresses and phone numbers from around the world, in real time. Send up to 100 requests per second using our Pay-As-You-Go plan, with no upfront costs or commitments required. Billing is seamlessly integrated with your regular AWS invoices.
How It Works:
- Our email address validation bypasses AWS port 25 (SMTP) blocking by providing an easy-to-use API endpoint to verify the validity of any given email. Our API returns a "Valid Email" response or "Error" responses in case of AddressFormatError or DNSError.
- With our phone validation API, you can verify the validity of any phone number worldwide, as well as obtain additional information such as area description, phone carrier, and time zone, if these informations are available.

Dimensions summary
This listing uses a single usage-based dimension. You pay for every request sent to the API, with no tiers or instance sizes to choose from. Pricing scales directly with your call volume — send more requests, pay more. There are no upfront costs, monthly fees, or long-term contracts. Both email address and phone number validation share this same per-request charge. Your usage-based charges appear directly on your AWS bill, so you do not set up a separate billing account. If your project exceeds 100,000 requests, you can contact the vendor for volume pricing.
Top-of-mind questions for buyers
Each call you send to the email-address or phone-number endpoint counts as one request. Both endpoints use the same per-request charge. Every submission is metered, whether the result comes back valid or invalid. The count is based on calls made, not on how many pass validation.
Yes. Charges apply to each request you send, regardless of outcome. A response marking an email as invalid or a phone number as unverifiable still counts as one billed request. Cost scales with the number of calls you make, not with successful validations only.
View your latest 1,000 requests in the online usage dashboard, or download your full request history as a CSV. For actual costs, use the AWS Cost Management console and filter by the vendor under Legal entity. Records begin from April 2025.
