Phone validation, on the credits you already use

You already clean your emails with Truelist. The phone numbers on the same list are usually in worse shape: typos, landlines in your SMS list, disconnected numbers your reps keep dialing.

We're adding phone validation to Truelist: upload a list or call the API, and find out which numbers are real, live, and textable before you spend on them. Join the waitlist and you'll be first in.

cell_tower Live line checks: Know whether a number is connected, not just correctly formatted.
smartphone Line type and carrier: Mobile, landline, or VoIP, plus which carrier the number is on.
payments Same credits: One balance for email and phone. Credits never expire.

Who it's for

Every list has phone numbers. Most of them go unchecked.

sms

SMS campaigns

Drop landlines and dead numbers before you send, so you stop paying for texts that never arrive and keep your carrier delivery rates healthy.

call

Sales and outbound

Validate the phone column on your prospect list along with the emails, so reps spend their time on numbers that actually ring.

dynamic_form

Signup forms

Check numbers in real time at signup. Block fakes and risky VoIP numbers, and store everything in a clean E.164 format.

How it will work

The same flow as email validation, for the phone numbers on your list.

upload_file 1. Upload or call the API: Upload a CSV with a phone column, or check numbers one at a time from your app.
verified 2. We check each number: Format, country, line type, carrier, and whether the line is live.
download 3. Export a clean list: Get every number back in E.164 with its result, ready for your CRM, dialer, or SMS tool.

Frequently asked questions

Have a question that's not here? Email our team.

What's the difference between this and the free Phone Validator?: The free tool checks a number against its country's numbering plan. That catches typos and fake numbers, but it can't tell you whether a line is connected or who the carrier is today. Phone validation adds live carrier network data, in bulk and through the API.
How much will it cost?: It will run on the same credits as email validation. We're setting the per-number rate now. Join the waitlist and tell us your volume to help us set it right.
Which countries will you support?: Format and line-type checks work worldwide. Live line and carrier checks will start with the countries our waitlist needs most, so let us know where your numbers are.
When will it be available?: We're building it now. Waitlist members get first access and early-tester pricing. In the meantime, the free Phone Validator handles single checks.
