Experian Phone Validation supports two ways to validate phone numbers. Choose the model that matches what you're trying to do today.
Use this when you need an instant response while someone is entering a phone number, helping you stop bad data at the point of capture and keep forms running smoothly.
When to use real‑time validation
How real‑time validation works
Ready to try it?
Make a real‑time test call to validate a single a phone number and see a response straight away, or explore the real‑time API reference to understand the available endpoints and how requests and responses are structured.
Use this when you want to validate a large list of phone numbers without anyone waiting for an immediate response. The service runs validation as an asynchronous, job‑based process, making it well suited to tasks like list cleansing, ongoing database maintenance, and pre‑campaign checks.
When to use bulk validation
How bulk validation works
Ready to try it?
Create a bulk validation batch using a small test set to see how the process works end to end, or explore the bulk API reference to understand the batch lifecycle, available endpoints, and how results are returned.
Real‑time validation is the right choice when someone needs an answer immediately while entering a phone number. It works one address at a time and returns a response straight away, making it ideal for forms, sign‑ups, and any flow where the user experience depends on instant feedback.
Bulk validation is the better option when you're working with large sets of existing phone numbers and don't need an immediate response. It processes addresses asynchronously in the background and lets you retrieve the results later, which suits list cleansing, database maintenance, and pre‑campaign checks.
